II.—On some Specimens of Dithyrocaris from the Carboniferous Limestone series, East Kilbride, and from the Old Red Sandstone of Lanarkshire
Authors: Woodward Henry , Etheridge Robert 
Published: May 2009

Dithyrocaris ovalis. W. and E. (Pl. V. Fig. 1), Mems. Geol. Survey, Expl. Sheet 23, Scotland, 1873, p. 100.This species most nearly resembles D. Colei in outline, but is little more than half its size, and is quite destitute of the strong median and lateral ridges which mark Portlock's species.
II.—On the Origin of the Loess
Authors: Wood Searles V. 
Published: May 2009

Various theories have been advanced to explain the origin of the Loëss of Europe, Asia, and North America, the latest having been that of Mr. Howorth, in the pages of this Magazine.Although possessing no knowledge of this formation, outside of England, beyond that derived from the descriptions of those personally acquainted with it, I have for some time thought that the Loëss has originated from an agency of which I detect evidences unong those phenomena of the Newer Pliocene period in England which I have endeavoured to trace in detail in a memoir on that subject laid before the Geological Society of London; but as the loëss in general is not discussed by me in that memoir, I venture to offer a few observations on the subject of it for the consideration of the readers of the Geological Magazine.
IV.—Additional Note on Homalonotus from the Devonian
Authors: Woodward Henry 
Published: May 2009

In the Geological Magazine, November, 1881, I published a brief description, accompanied by a Plate, of a new species of spinose Homalonotus, which I named after its discoverer, H. Champernownei.On the accompanying Plate IV. Fig. 3, 1 have given an illustration, of the tail probably referable to the above-named species.
III.—On the Detection of Mural Pores in thin Sections of the Favositidæ
Authors: Nicholson H. Alleyne 
Published: May 2009

As a text for the following brief remarks on the recognition of mural pores in thin sections of the Favositoid Corals, I may quote a note appended by Mr. James Thomson, F.G.S., to a recent paper on the genus Lithostrotion (Trans. Edin. Geol. Soc. vol. v. part iii. p. 381). The note in question is subjoined, the quotation being verbatim, and, I may add, literatim also:—“We may, however, attach an undue importance to microscopic examinations. Need I refer to the point raised recently by that erratic and energetic worker, Prof. Alleyne Nicholson, regarding mural pores in the genus Alveolites, the type of which is also in Dr. Fleming's collection. If he had detected mural pores in microscopic sections, we would have regarded such as being one of the greatest discoveries of modern times.
VIII.—Notes upon Ice Action in High Latitudes
Authors: Spencer J. W. 
Published: May 2009

These notes are intended as an appendix to “Notes on the Erosive Power of Glaciers, as seen in Norway” (vide this Magazine, Decade III. 1887, Vol. IV. No. 4, p. 167).1. The object of my visit to Norway and the Alps was to leave closet-geology in America, in order to make personal observations of the phenomena associated with modern glaciers,—for comparison with those in the region of our Great Lakes, often attributed to land-ice.
V.—The “Great Submergence” Again: Clava
Authors: Bell Dugald 
Published: May 2009

A Few years ago, in one of three or four papers treating of the “high-level shelly clays” of Scotland, I referred at some length to the interesting section at Clava, near Inverness, first described by Mr. Jas. Fraser, C.E., and inquired—Is it part of an old sea-shore or bottom, laid down by the sea where we now find it, and therefore proving a submergence of at least 500 feet ?I submitted a number of facts and considerations which, I thought, tended to show that this instance at Clava cannot be received as a satisfactory proof of submergence.
V.—On a Mode of Using the Quartz Wedge for Estimating the Strength of the Double-Refracton of Minerals in Thin Slices of Rock
Authors: McMahon C. A. 
Published: May 2009

In some cases it is of practical importance to petrologists to estimate the strength of the double-refraction exhibited by doubly-refracting minerals in thin slices of rock under the microscope.Babinet's compensator, a description of which will be found in Rosenbusch's Microskopische Physiographic der Mineralien und Gesteine, affords a means of accurately calculating the refractive indices of the rays into which light is divided in its passage through doublyrefracting crystals. Michael-Lévy also devised another exact method based on observations made on the tints presented by slices of doublyrefracting minerals, an account of which appeared in the Bulletin de la Societe Mineralogique de France, and which is discussed in a work recently published by Michael-Lévy and Lacroix.
VI.—On a Remarkable Dyke in the Serpentine of the Lizard
Authors: Somervail Alex 
Published: May 2009

The dyke in question occurs at the extreme north end of Pentreath Beach, which is about a quarter of a mile to the south-east of Kynance Cove.The dyke forms a portion of the “granulitic group” of Prof. Bonney, which is now known to be of igneous origin, and consists of banded gneissic rocks, some of which are like a granite, other portions like a diorite, the latter always more or less porphyritic.
V.—Catalogue of the known Foraminifera from the Chalk and Chalkmarl of the South and South-Eastern Counties of England

The sources of information are given below.D. From T. Rupert Jones's Catalogue of the Foraminifera from the Chalk and Chalkmarl in the Second Edition of Dixon's “Geology and Fossils of Sussex,” 1878, pp. 284 and 285.
III.—Notes on British Geological Photographs
Authors: Watts W. W. 
Published: May 2009

As promised last month, we now add a brief note on Plates III and IV of this series, given in this number.Plate III is one of a beautiful set prepared by Mr. Godfrey Bingley for insertion in the Proceedings of the Yorkshire Geological and Polytechnic Society, from which the plate is borrowed by the kind permission of the editor, the Rev. W. L. Carter. A full description by Mr. G. W. Lamplugh will shortly appear in the “Proceedings” of that Society, and from the manuscript of this I have been permitted to extract the following:—The cliff to the left is the most easterly point of Flamborough Head; it is formed of the lowermost beds of the flintless Upper Chalk, resting on the uppermost beds of the flinty Middle Chalk, which are seen just above sea-level. In the Chalk a steep-sided valley has been eroded which is now filled with drift.
VI.—The Culm-measures at Bude, North Cornwall
Authors: McMahon C. A. 
Published: May 2009

My paper on the Culm-measures at Bude has elicited two communications, from Messrs W. Maynard Hutchings and Alfred Harker, on which I desire to offer a few comments.I take this opportunity of saying that I am extremely glad to find that the conclusion at which I arrived regarding the impotence of pressure alone to produce metamorphism is in accord with the published views of my friend Mr. J. J. Harris Teall. “Pressure” alone, he states, in a footnote at p. 410 of his valuable work, British Petrography, “produces no effects on rocks—work must be done upon rocks before change takes place.” This footnote escaped my memory at the time of writing my paper, or I should have called attention to it.
IV.—On some Fossil Entomostraca from South America
Authors: Jones T. Rupert 
Published: May 2009

There are now in the British Museum (Natural History Branch) several specimens of fossil Estheriæ from South America, beside those described and figured in the “Monograph of Fossil Estheriæ” (Palæontographical Society), 1862, pp. 109–111, pi. iv, figs. 8–11.1. There are some from the same locality as those already dealt with, namely, Estheria Forbesii, Jones, from Cacheuta in the province of Mendoza, Argentine Republic.2. Others collected by David Forbes at another place, namely, Arica, Department of Arequipa, in Southern Peru.3. An interesting series from Brazil; partly described and illustrated in the Geological Magazine for May, 1897, pp. 195–202, PI. VIII.
II.—On some Recent Contributions to Precambrian Geology
Authors: Blake J. F. 
Published: May 2009

The last two numbers of the Quarterly Journal of the Geological Society contain three communications concerning rocks which are, or are thought to be, Precambrian. Two of them are in direct attack on work of mine, and the third incidentally opposes some portion of it. The materials of any reply I may have to make are, for the most part, already published in my papers, but the bearing of these facts seems to require to be pointed out.Taking the communications in order, the first is the Anniversary Address of the President. In this he deals, so far as my work is concerned, first with Anglesey. Sir A. Geikie states that he was not prepared by previous writings for certain results he obtained. He was much astonished to find in central Anglesey so striking a counterpart to portions of the old gneiss of the north-west of Sutherland and Ross.
II.—On the Superimposed Draninage of the English Lake District
Authors: Marr J. E. 
Published: May 2009

“What was the condition of our present mountain tract during the great Carboniferous period? Was it wholly submerged after the elevation and denudation to which we have already seen it subject, or was there always a nucleus of dry land—an embryo of Cumbria—around which the Carboniferous deposits were laid down? I do not think this is a question that can ever be decidedly answered.”It is a question which has frequently been asked, and the answer given are various. In the present communication I intend to loo at it from a somewhat different point of view from that in which has usually been approached, though the view here adopted in man respects resembles that taken by the late Mr. Hopkins.
IV.—On Soda-Microcline from Kilimandscharo
Authors: Hyland J. S. 
Published: May 2009

The material, in which this felspar occurs, was collected by Dr Hans Meyer during his visit in 1887 to the East-African “snowmountain,” the Kilimandscharo, and kindly entrusted to me for description by Prof. F. Zirkel of Leipzig, to whom I desire to express my indebtedness for assistance and advice supplied me whilst working in his laboratory.The rocks which possess this mineral as felspathic constituent are Nepheline- and Leucite-basanites, and were found in sitû on the south and south-east flanks of the Kibo peak. As rock-constituent this felspar is presumably confined to the outflows from the higher peak—the Kibo4—as no trace of it is to be found in the large series of rock-specimens, which represent the materials of which the other and lower peak—the Kimawenzi—is formed.
V.—On some Physical Changes in the Earth's Crust
Authors: Ricketts Charles 
Published: May 2009

On the western flanks of the Malverns, the Upper Silurians are folded in several great anticlinals and synclinals, formed parallel to the axis of the Hill itself. To the west of Ledbury and again near Woolhope these contorted strata dip beneath the Old Red Sandstone, which, as computed by Phillips, has a maximum thickness of 8000 feet, that of the Upper Silurians being 2690 feet.The thickness of the strata of which the Longmynd is formed has been estimated by the Government Surveyors at not less than 26,000 feet, as exposed in their highly inclined edges; the beds dipping at an average inclination of 60° to the W.N.W. They thus appear as if they had been tilted by pressure against the more ancient rocks of the Caer Caradoc Range.
IV.—Comparison of the Principal Forms of Dinosauria of Europe and America
Authors: Marsh O. C. 
Published: May 2009

The remains of Dinosaurian reptiles are very abundant in the Rocky Mountain region, especially in deposits of Jurassic age, and during the past ten years the author has made extensive collections of these fossils, as a basis for investigating the entire group. The results of this work will be included in several volumes, two of which are now well advanced towards completion, and will soon be published by the United States Geological Survey.In the study of these reptiles, it was necessary to examine the European forms, and the author has now seen nearly every known specimen of importance. The object of the present paper is to give, in few words, some of the more obvious results of a comparison between these forms and those of America which he has investigated.
III.—On the Origin of the Stone-Rivers of the Falkland Islands
Authors: Davison Charles 
Published: May 2009

The stone-rivers of the Falkland Islands have been described by Mr. Darwin, Sir Wyville Thomson, Dr. Coppinger, and other naturalists who have visited those regions. The accounts given by the two first-named are well-known and easily accessible, and render a full description here unnecessary. But it may not be out of place to summarise the principal features of the stone-rivers, which must find an explanation in any satisfactory theory of their origin.They consist of angular blocks of quartzite, “arranged,” according to Pernéty, “as if they had been accumulated carelessly to fill the ravines.” The blocks are from two to twenty feet long, and rest “irregularly one upon the other, supported in all positions by the angles and edges of those beneath” (Thomson).
VIII.—Notes on the Lower Palæozoic Rocks of the Fichtelegebirge, Frankenwald, and Thüringerwald
Authors: Marr J. E. 
Published: May 2009

During the summer I visited Hof with Professor Nicholson, mainly in order to examine the Graptolite-bearing shales of the surrounding region. These we found to be far from rich in fossils, and the principal fossil-bearing localities were remote from one another. Under such circumstances little could have been accomplished, but for the kindness of Herr Glass, of Hof, who allowed us to examine his fine collection of fossils from the district. To him I would tender my best thanks, as also to Prof. Geinitz, who not only permitted me to examine his rich collection of Graptolites from the Thüringerwald preserved in the Dresden Museum, but also devoted some of his valuable time to me.For a full account of the Lower Palæozoic rocks of the region under consideration, I may refer to Prof. Gümbel's exhaustive “Geognostiche Beschreibung des Fichtelgebirges mit dem Frankenwalde und dem Westlichen Vorlande.”
I.—On the Discovery of the Larval Stage of a Cockroach, Etoblattina Peachii, H. Woodw., from the Coal-Measures of Kilmaurs, Ayrshire
Authors: Woodward Henry 
Published: May 2009

By the kindness of Mr. B. N. Peach, F.R.S.E., F.G.S., of the Geological Survey of Scotland, I have been permitted to examine a very interesting insect-remain enclosed in a light-brown nodule of Clay-Ironstone, obtained fram Kilmaurs, Ayrshire.In February last I had the pleasure to describe three new forms of British Carboniferous Cockroaches, viz.:—1. Etoblattina Johnsoni, H. Woodw., Coal-Measures, Coseley, near Dudley.2. Leptoblattina exilis, H. Woodw. do. do.3. Lithomylacris Kirkbyi, H. Woodw., U. Coal-Measures, Meithil, Fife.Mr. S. H. Scudder, of Boston, has described no fewer than 30 species from the Coal-Measures of N. America, whilst 41 species have been described by Goldenberg, Heer, Germar, Scudder, and others from the Coal-Measures of Europe, so that this group of Orthopterous insects was perhaps almost as well represented in the Coal-period as at the present day, and nearly as widely distributed geographically.
VIII.—Bursting Rock Surfaces
Authors: Hughes T. McKenny 
Published: May 2009

The interesting note by Mr. Strahan in the Geol. Mag. for September, 1887, on explosive slickensides, reminded me of some similar phenomena which were not of unfrequent occurrence near Dent Head and Ribble Head in Yorkshire.In the limestone quarry from which the black marble of Dent is procured the workmen found that, when they were quarrying the lower beds and struck the rock with a pick or bar, fragments flew up into the air with greater force than, could be due to their blow and in an unexpected direction.
I.—Eocystis, I. Eocystites primævus Hartt
Authors: Bather F. A. 
Published: May 2009

The second edition of J. W. Dawson's Acadian Geology (1868) contains some notes communicated by C. F. Hartt. One of these, on p. 643, runs as follows:“Eocystites primçvus, Billings, Coll. Hartt (Fig. 220). The little plate with radiating sculpture, represented somewhat enlarged in the figure, is regarded by Mr. Billings, to whom the specimens have been submitted, as indicating anew genus of Cystideans.”In this perfunctory manner, without diagnosis or description, was the genus Eocystites founded. Since a named species was mentioned, that species, E. primçvus, must be taken as genotype, and the generic name is thereby validated.
III.—The Lower Cretaceous Series of the Vale of Wardour
Authors: Jukes-Browne A. J. , Andrews W. R. 
Published: May 2009

It has long been known that certain deposits of Lower Cretaceous age lay between the Gault and the Purbeck group in the Vale of Wardour, but the absence of any good open sections, along the tracts where they reach the surface, has hitherto prevented geologists from ascertaining the exact nature and succession of the beds.Dr. Fitton, whose account of the Vale of Wardour is wonderfully good and accurate, distinctly recognized the existence both of Wealden and Vectian (Lower Greensand), stating that certain sands, containing traces of marine shells, occurred beneath the Gault and above the clays which he regarded as Wealden.
VII.—On the British Earthquakes of 1889
Authors: Davison Charles 
Published: May 2009

Time of occurrence, 22h. 36 m.: Intensity, VI. Epicentrum about two miles N.N.E. of Bolton, half a mile west of the village of Bradshaw.This interesting earthquake affected a district for the most part thickly populated, and the accounts of it are consequently numerous. In the newspapers mentioned below, records are given of observations from 156 towns and villages, situated within a nearly circular area about 55 miles in diameter. Considering the smallness of this area, I suppose that but few previous earthquakes have afforded materials so abundant for the seismologist.
I.—Fossil Fishes in the Devonian Rocks of North Devon
Authors: Rogers Inkermann 
Published: May 2009

The Devonian rocks in Devon, like those of the Old Red Sandstone of which they are the equivalents, have been divided into three groups. Mr. T. M. Hall, writing in 1879, quoted no less than five separate classifications suggested for the beds of North Devon, nor has uncertainty been removed by the conclusions arrived at by geologists since that date. But we may for present purposes take the following as the nearest approach to a generally accepted succession:—While examining the rocks of the Middle and Upper series for fossil plants during the past eleven years (1907–18), the results of which have already in part been published, other discoveries were made incidental to the work of collection of plant remains. Among these the discovery of fossil fish remains seems worthy of special notice.
I.—On the relative Ages of the Coast Boulder-clay of the Eastern Counties, and that on the Higher Ground
Authors: Maw George 
Published: May 2009

The discussion on Mr. Boyd Dawkins's paper, “ On the age of the Lower Brick-earths of the Thames valley,” at the meeting of the Geological Society of London, 9th of January, induces me to submit a view of the relative ages of the Boulder-clays of the east of England, which seems to bring into harmony the views of Mr. Dawkins, and the physical evidence suggested in the discussion that seemed to conflict with them.Mr. Dawkins' opinion that the lower deposits of Brick-earth at Grays' Thurrock, Crayford, and Erith were super-imposed by a Glacial deposit containing transported materials, was objected to on the grounds that they occur in a valley apparently excavated after the deposition of the Boulder-clay capping the high land to the north of London—implying an interval between the Muswell Hill Boulder-clay, and the supposed Glacial deposits of the Thames Valley, represented by the entire excavation of the valley, and the deposition of the Brick-earths and gravels, containing mammalian remains, underlying the Glacial beds.
IV.—On the New Species Olenus Nuneatonensis and Obolella granulata, from the Lower Silurian (‘Cambrian,’ Lapworth), near Nuneaton
Authors: Sharman George 
Published: May 2009

Locality.—West end of the Midland Railway cutting, between Nuneaton and Stockingford.Several fragmentary specimens of this Trilobite, differing in size, yet exhibiting similar characters, have been collected from this locality. The most perfect, although one of the smallest, is best fitted for description.
Decadent truncation: liberated Eros in Arthur Vincent Lourié's The Blackamoor of Peter the Great
Authors: MÓRICZ KLÁRA 
Published: May 2009

AbstractRussian composer Arthur Vincent Lourié (1881/2–1966) dedicated his The Blackamoor of Peter the Great (1948–1961), an opera based on Pushkin's story about the poet's African great-grandfather, to ‘Russian culture, the Russian people and Russian history.’ Neoclassical in its subject matter, reliance on conventional musical forms, and adherence to tonality, Lourié's Blackamoor is nevertheless also an exemplary symbolist opera. This article explains three symbolist aspects of the work: the sources of its libretto (Lourié's librettist Irina Graham interspersed the libretto with symbolist texts), its multi-layered cultural associations, and Lourié's decision to liberate and embody the erotic drive of the main character Ibrahim by representing it as the figure of Eros. Eradicated during the years of Stalinist terror, the culture of Silver Age Russia thus continued to find a voice in the emigrant Lourié's last opera.
Hysteroscopic female sterilization with Essure® in an outpatient setting
Authors: ANDERSSON SONIA , ERIKSSON SOFIE , MINTS MIRIAM 
Published: May 2009

AbstractThe aim of this study is to evaluate the short and long‐term results of hysteroscopic sterilization in an outpatient setting. Sixty‐one women underwent hysteroscopic sterilization. At follow‐up, all of the women were asked to complete a questionnaire concerning possible pregnancy, bleeding patterns, side‐effects, or need for further therapy after sterilization. Technical feasibility, complications, patient satisfaction, and tubal occlusion based on X‐ray or ultrasound were measured. Fifty‐eight (95%) women were sterilized according to this method. Successful bilateral device placement was achieved in 52 women (85%) during the first attempt and in six (9.8%) during the second. A total of 50 (81.9%) women submitted completed outcome questionnaires. The mean follow‐up period was 23 (range 7–67) months. No pregnancies were reported. All questionnaire respondents expressed overall satisfaction with the procedure. To conclude, Essure® sterilization is a safe effective method for female sterilization that is feasible in the outpatient setting.
Germination of Wheat: A Functional Proteomics Analysis of the Embryo
Authors: Mak Yunxian , Willows Robert D. , Roberts Thomas H. , Wrigley Colin W. , Sharp Peter J. , Copeland Les 
Published: May 2009

ABSTRACTGermination in the soft wheat (Triticum aestivum L.) cultivar Rosella was followed for three days after imbibition by proteomic analysis of the germ tissue. Two‐dimensional electrophoresis was performed in triplicate for proteins extracted from embryos dissected from mature grain and from grains germinated for 1, 2, and 3 days. For this period, 63 proteins (in 86 spots) in the germ were identified as decreasing in abundance, 35 proteins (in 60 spots) as increasing in abundance, and 28 proteins (in 39 spots) as exhibiting no significant abundance change. Proteins with significant abundance changes are discussed in relation to physiology; these include proteases, amylases and amylase inhibitors, enzymes in lipid metabolism, proteins related to water stress, cell wall hydrolases, oxalate oxidase, and H+‐ATPases. Functions associated with proteins synthesized during the germination period are inconsistent with the embryo of mature grain being fully primed for germination.
