were stained by the Fink-Heimer technique. Two main olfactory pathways are observed, tractus olfactorius lateralis and tractus olfactorius medialis. Degenerating axonic terminals are shown in two fields, one in the ipsilateral and the other in the contralateral posterior hemisphere. Histochemistry Histochemistry of the First Stages of Mineralization of Carcinus maenas Cuticle. Attempt of Localization of Carbonic Anhydrase, by Marie-Madeleine Giraud 1541 The calcification of the cuticle occurs a short time after the molt. It spreads in depth along the septae limiting a system of prisms. These septae contain acid mucopolysaccharide, and show a strong affinity for carbonates. Carbonic anhydrase could also be localized in these septae. Insect Physiology Synergistic Action of Carbohydrate and Terpene Components in the Secondary Attraction Process and the Mechanism of Pheromone Elaboration in Scolytidae Conifer Parasites, by Constantin Chararas... 1545 The author describes the results of experiments in primary and secondary attraction in Scolytidae species of genus Ips, Pityophthorus, Pityogenes and Orthotomicus. Pheromone production by males is influenced by nutritional factors (carbohydrates of host sap) and terpene component. Bacterial conversion of ingested monoterpens is possible but not essential in the pheromones elaboration. Independence of Food Yield and Weight at Emergence with and Without Under Nourishment in Acanthoscelides obtectus Say on Phaseolus Vulgaris, by Jacques Lerin 1549 The heterogeneity of adult's weight at emergence when larvae are crowded in Acanthoscelides obtectus Say is caused by the variability of the amount of space and food at the disposal of competing larvae and not by a modification of the "ecological efficiency". A correlation coefficient of 0.93 appears between larval consumption and adult's weight at emergence. This adaptation to crowding allows the survival of a great number of individuals and the persistence of a diversified gene pool. Invertebrate Physiology Oviposition of Drosophila Melanogaster Under LD 12:12 Light Conditions: Effects of Light Intensity Upon The Expression of the Daily Rhythm, by Roland Allemand 1553 Under photoperiodic conditions LD 12: 12, the oviposition rhythm is dependent on the light intensity received during the photophase.

Invertebrate Physiology Oviposition of Drosophila Melanogaster Under LD 12:12 Light Conditions: Effects of Light Intensity Upon The Expression of the Daily Rhythm, by Roland Allemand 1553 Under photoperiodic conditions LD 12: 12, the oviposition rhythm is dependent on the light intensity received during the photophase. With a low intensity (under 60 lux) a bimodal rhythm was observed whereas with higher intensities, it became unimodal. The oviposition peak at the beginning of the darkness increased with light intensity while egg production during the last hours of the photophase decreased. These data demonstrate the preponderance of external conditions upon oviposition rhythmicity in D. melanogaster. Comparative Physiology Absence of Correlation Between Oxygen Content of External Medium and Sodium Efflux Across the Gills of Carassius auratus in Fresh Water and of Mugil capito in Sea Water, by Jean Maetz, Pierre Pic and Pierre Lahitte 1557 Considerable variations in the oxygen content of the external medium inducing important alterations in gill ventilation and blood flow but compatible with survival of the Fish (partial oxygen pressure range: 30 to 600 torr) are not followed by any significant changes in the branchial sodium efflux. Biology Peritoneal Exudate with Mononuclear Leukocytes Observed During Normal Pregnancy in Various Species, by Jeanna Schwartz, Andre Evquien and Stephane Chaux 1561 A peritoneal, cell-rich fluid, containing mononuclear leukocytes, macrophages, monocytes, mast cells and lymphocytes, was observed during normal pregnancy in animals belonging to various species. These cells might be concerned in a homograft-like, mother-foetus, relationship.

Experimental Biology Effects of Radio-Frequency Lesions at Different Loci of the Encephalon on the Mitotic Rate in the Glandular Epithelium of the Small Intestine in the Rat, by Mauro Bindoni, Antonio Bava, Stefania Stanzani, Caterina Campione and Innocenzo Nicotra 1565 Radio-frequency lesions of tubero-infundibular region of the hypothalamus are followed by a significant increase of the mitotic rate in the small intestine glandular epithelium in Rats. This increase does not occur when radio-frequency lesions are located in the anterior and posterior hypothalamus, in the dorsomedial thalamus and in the cerebral hemispheres. Ecology Estimation of Specific Diversity of Phytoplankton from the Number of Cells Determined by a Scale of Classes, by Jean Devaux and Guy Millerioux 1569 The authors used the scale of classes proposed by Frontier for the estimation of specific diversity. This index is calculated with the upper limits of the classes where each species is placed. A good agreement is found with specific diversity calculated with the classical enumeration. Ecophysiology Manganese Accumulation by Plants on Ultrabasic Rocks in New Caledonia, by Tanguy Jaffre 1573 Alyxia rubricaulis (Apocynaceae) and several species of Maytenus (Celastraceae) accumulate manganese in their leaves to very high concentrations, over 3,2 % in Maytenus bureaviana on basic hypermagnesian soils. The concentration of manganese in Alyxia is only high for plants growing on acid soils, while

The concentration of manganese in Alyxia is only high for plants growing on acid soils, while in Maytenus it depends mainly on the manganese concentration in the soil and is independent of pH. This raises the problem of manganese absorption by the roots from poorly soluble compounds. Seasonal Changes in Plasma Levels of Testosterone and Thyroxine in the Male European Badger, by Daniel Maurel, Janie Joffre and Jean Boissin 1577 In the male European Badger there are important variations in the plasma testosterone and thyroxine levels during the annual cycle. During the summer, plasma testosterone concentrations are low while plasma thyroxine rises to a very high level. In winter, when the thyroid activity is minimal, testicular activity increases. From February to May, the plasma testosterone remains at a high level, and then, after a sudden fall, a second peak occurs in June at which time the concentration of thyroxine is low. Population Dynamics Morphometric Study of Populations with and without Diapause of a Cricket from Algeria, by Jacques Rouault and Suzel Fuzeau-Braesch 1581 The morphometric study concerns 15 characters treated by multivariate analysis with principal component analyses. The populations of the Cricket in Hauts-Plateaux of Algeria with and without "diffuse" diapause differ only in their size. This difference is related to the increase in the number

Split Dose Effect on Survival of Axillary Buds From Haploid and Diploid Nicotiana Sylvestris, by Jean Mousseau and Monique Delbos 1585 An irradiation effect, measured as survival percentage, has generally less consequences when given as split dose than continuously. When split doses are separated by a long enough time, 2 or 3 hrs, a protective effect from the first irradiation against those following may appear. Study of the Microwaves of the Tanning Process in Tenebrio molitor L., by You Hing Tchao, Claude Huel and Jean-Jacques Lenoir-Rousseaux The anterior part of Tenebrio molitor releases enzymatic substances inducing the tanning process of the adult cuticle. These substances would be released before larval-pupal ecdysis. Their presence at a low rate enables the tanning process to occur normally although later. Plant Biochemistry Studies on the Composition of Grindelia squarrosa and Grindelia aphanactis (Compositae), by Madeleine Pinkas, Monique Torek and Lucienne Bezanger-Beauquesne The authors have identified kempferol-3-methylether, quercetol-3,3'-dimethylether, kempferol-3,7-dimethylether in the flowers of Grindelia squarrosa, kempeferol-3-methylether and quercetol-3,3'-dimethylether in the flowers of Grindelia aphanactis.

Biochemistry Report of a N-acetyl-galactosaminyltransferase Activity During the Murine YC8-Lymphoma, by Framboise Raimond-Pironneau, Nicole Achy-Sachot, Maximilienne Turpin and Evelyne Morel The N-acetyl-galactosaminyltransferase activity has been studied in the biological fluids of YC8-lymphoma bearing Balb/c mice. It is enhanced during tumor development from 1 to 30 times in peritoneal fluids and from 1 to 10 times in sera. This activity is nil in urines. Optimal requirements for activity have been determined. Results suggest the existence, during tumor process not only of an enhancement of enzymatic activity, but also of a new molecule synthesis, molecules which are endogenous acceptors for the enzyme. Pharmacology Study of the Antagonism Between Corticoadrenal Extract and Prostaglandin E2, by Pham-Huu-Chanh and Pham-Huu-Chanh Corticoadrenal extract has been shown to antagonize the action of prostaglandin E2 (Pg E2) on smooth muscle: this effect is noteworthy. It could partly elucidate the mechanism of the antihypotensive action of corticoadrenal extract.

Immunology Hemopoietic Stem Cells Preferential Differentiation After Transfer Into Lethally Irradiated Mice Previously Infected With BCG, by Gilles Marchal and Geneviève Milon Following injection of bone marrow cells in lethally irradiated mice, previously infected with BCG regenerating hemopoietic cell populations differentiate along the leucocyte pathway to the detriment of erythroid lineage. Such a phenomenon persisting even if anemia of infected mice is increased by bleeding just before irradiation and reconstitution supports the hypothesis of preferential differentiation of stem cells. Immunochemistry Immunochemical Studies of the Hemolymph Proteins of Sacculina carcini Thompson, by Charmaine Herberts The hemolymph proteins of Sacculina carcini, a parasite of Carcinus mediterraneus, are compared with those of the host. The immunochemical analysis revealed ten antigenic components. The absence of reaction of one fraction separated by electrophoresis is discussed. Immunobiology Radioprotection Induced by Corynebacterium Parvum Against Lethality Provoked by Irradiation X at Sublethal and Lethal Doses in Mice, by Bernard Halpern and Simonne Andre Intraperitoneal injection of Corynebacterium parvum (C. parvum) into Balb/c Mice produces a protection against toxicity or lethality provoked by ionizing radiation (750 R and 950 R). Survivals reaching nearly 90 days have been recorded. Cette hypothèse est confirmée par la présence éparse de disthène et de feldspaths très perthitiques relictuels au sein de la trame anatectique.

DÉFORMATION. — Nos observations microtectoniques ont porté essentiellement sur la série leptyno-amphibolique où la présence de nombreux bancs compétants d'amphibolites et de leptynites permet d'observer les phases superposées. Nous avons pu mettre en évidence trois grandes phases de déformation : la première phase déjà mentionnée par F. Carme correspond à la foliation majeure, et sans doute à des plis isoclinaux dont la direction n'a pas été reconnue pour l'instant. On n'observe pas de linéation d'allongement liée à cette phase. Les axes de boudins sont également dispersés ce qui laisse supposer une composante d'aplatissement importante. Néanmoins, il est difficile de séparer les boudins des phases 1 et 2; — la deuxième phase donne des plis déversés à couchés vers le sud-ouest, d'ampleur métrique à kilométrique. Ces plis replissent la foliation S 1. Ils ont une schistosité de type « strain slip » passant localement dans les pélites à une foliation S 2 à biotite-sillimanite. À la phase 2 est associée une linéation minérale très marquée, parallèle aux axes des plis (NW-SE) ainsi que du boudinage de direction N 20° à N 30°. Cette phase est sans doute liée à la tectonique tangentielle de grande ampleur (chevauchement majeur vers le sud) présente par F. Carme. — la troisième phase est à l'origine de nombreux

Cette phase est sans doute liée à la tectonique tangentielle de grande ampleur (chevauchement majeur vers le sud) présente par F. Carme. — la troisième phase est à l'origine de nombreux plis en chevron, centimétriques et, selon la région, de plis NS ou EW, sans schistosité, donnant, en particulier dans le Haut-Ailier, une structure en dômes et cuvettes. RELATIONS DÉFORMATIONS-CRISTALLISATIONS. — Dans la série leptyno-amphibolique. — Les relations entre ces déformations et l'histoire métamorphique complexe de cette région n'avaient pas jusqu'à maintenant été clairement établies. Nos observations, en particulier dans la vallée de la Truyère, ont permis de montrer que l'amphibolitisation des éclogites et des gabbros est contemporaine de la phase 2. Dans ces roches basiques on observe les réactions suivantes : omphacite → diopside + plagioclase acide, hornblende brune → plagioclase laitu → hornblende verte + plagioclase 2. Les minéraux résultants cristallisent en couronnes caractéristiques autour des minéraux primaires. Ces couronnes ont une forme d'ellipsoïde dont les axes principaux sont parallèles aux axes géométriques des plis postfoliaux de phase 2. Ces ellipsoïdes sont bien reconnaissables en particulier dans les gabbros avec X parallèle à B, de direction 120-130°, Y parallèle à A et Z perpendiculaire à (A, B). Dans les gneiss pélitiques on observe également des ellipsoïdes à quartz-sillimanite ayant des rapports d'axes comparables et des relations identiques avec les plis de la phase 2. Dans les anatexites à cordiérite.

Dans les anatexites à cordiérite. — La complexité microtectonique de cette série est due principalement à une anatexie diffuse qui efface les marqueurs de la déformation. On peut, néanmoins, reconnaître une succession de déformations identique à celle établie dans la ceinture leptyno-amphibolique. L'anatexie se développe au cours de la phase 2 et persiste après celle-ci pour s'achever entre cette phase et la phase 3. Les plis de phase 2 s'accompagnent de cisaillements chauds, injectés de filonnets de granité. La blastèse de la cordiérite est contemporaine de l'anatexie; elle se présente en taches non déformées. Nous n'avons pas retrouvé de cordiérite « ancienne » déformée signalée par F. Carme. La phase 3, postérieure à l'anatexie, se fait encore dans des conditions de température élevée (arcs polygonaux de biotite). C'est elle qui déforme tous les minéraux antérieurs et, en particulier, les taches de cordiérite. CONCLUSION. — Dans les régions du Haut-Ailier et de la Truyère, les observations microtectoniques permettent de montrer que les séries chevauchantes ont subi une rétromorphose généralisée comme le supposait F. H. Forestier et coll. La amphibolitisation est contemporaine de la phase 2, elle-même postérieure à une première foliation. Les relations entre les assemblages granulitiques de haute pression et les déformations successives ne sont
