 SCIENTIFIC MISCELLANY

origin in man is believed to have occurr.A | recently in Paris.
 A number of travelling juries have been created by the French government to yis;, foreign lands and collect information us.4,, to science, commerce and navigation.
 The eye of a rabbit has been success. fully transplanted to a human subject Tb. movement and appearance of the natural eve was excellently secured, vision not being e,. pected.
 The schools of Austria have been for. bidden using paper ruled in square or diago. nal lines, as such paper has been found ia injure the eyesight of pupils. In future oplv paper plain or ruled straight across is ,o he employed.
 Attention has been called to the fact tha, the streams in certain cultivated portion, of northern Texas now run during the part of the year when they were formerly dry. rbis IS not attributed to any change in the rainfall but to more even absorption of water over the cultivated areas.
 The curious and remarkable discoverv is reported that South American sbruh called "aliza," exudes juice which acts SO powerfully in stopping flows of blood tha, when knife is smeared with it and used for surgical operations, the largest vessels may be severed without any hemorrhage.
 in span, according to a government report, s53 earthquakes occurred during the nine and half years proceeding December. ISs+. The record is evidently incomplete. however, as Prof. Milne has been able to trace an average of an earthquake a day in Nagasaki, ia the extreme south of Japan.
 A Mechanical Observatory.-A me. neurological station is about to be established among he highest mour tains of Mexico, at an elevation of nearly 20 900 f. ct above sea-level
 AS access to such place is difficult and often impossible, the recording apparatus will have to be made almost independent of human at tention, and, as far as possible, all the instru- Rents will be made to run a year withou, stopping.
 The Plant for Banks.-Experience on French railways has shown that the double poppy is the best plant at present known for consolidating, by tbe interlacng of its roots, the loose soil of an embankment The usual grasses and clovers develop slowly, bu, the double poppy grows enough in two weeks to give some protection to the slope, and within three or four months its roots, ten or twelve inches long, retaia the earth far more firmly than those of any grass or grain.
 The Microscope in Business.-A mem- Der of the London Microscopical Society has described case illustrating the value of the microscope as detective agent. Fraudu. lent additions were made to bond, and the ink being darker than the original the fcrser traced over the whole writing to give it a un- form shade. Under the microscope the diff ference between the original and the added portion was clearly discernible, and the for gery was established.
 Use of the Power at a Distance.- French experiments on the transmission of power by electricity have resulted less sue cessfully than was hoped. theoretically the plan is feasible, but it is found to be more economical and practicable for mauufactur- ing purposes to use the power directly at the source of supply. Modern railway facilities make it cheaper to transport goods than power, with it's attendant loss of fifty per cent-not to mention its uncertainties.
 Arctic Coal-Commenting on Lieuten- ant Greely's discovery of ceal within the Arc tic circle in Greenland, Mir. W. Mattieu Will Hams expresses himself as dissati. fled with the prevailing notion which demands a sub tFOnical clima fa fOrS Sh fop ofo~ erous deposits. He has himself described the deposition of coal that is in actual pro- sress at the present time in Norway, within four degrees of the Arctic circle, and believes that similar deposits may be found farther north. No very violent alteration of climate, therefore, need be assumed to explain the Greenland coal.
 Forest h rfuence on Climate.-In a pa per read before the Royal Meteorological Society of London, Dr. Woeikof stated that the first step towards a scientific investigation of the influence of forests upon climate was taken by the establishment of the Bavarian forest meteorological stations. This exam pie was followed by Germany, France, Switz- erland, Italy, and other countries. In general it has been found that during the warmer sea- son the air and earth temperatures are lower in the forests than in neighboring woodiess places; that their variations are less, and that the relative humidity is greater. dis cussion of this question shows that in the western portions of the old world extensive forests materially influence the temperature of neighboring localities, and that the normal increase of temperature from the Atlantic ocean towards the interior of the continent is not only interrupted by their agency, but they cause the summer to be CT o'er n regions situated further in the interior than those nearer the sea. Hence, forests exert an in influence on climate which does not cease at their borders, but is felt over greater or less district according to the size, kind, and posi- tions of the forests. It follS~s from this that |
