Factors of acclimatization of European animals in Algeria and in other 

 ■warm countries, T. Monod (Dcs Factciirs de UAccUnuitation clu h^tail 

 Enropeen en Algerie et dans les Pays Chauds. Etampes, France: Assoc. Sci. 

 Internat. Agron. Colon., 1909, pp. 27 ) .—Besides a general consideration of the 

 effect of climatic factors and the change of food, results are reported which 

 have already been obtained in introducing European breeds of live stocl^ into 

 Algeria. 



Essential factors in the acclimatization of European animals in Tonkin, 

 E. DouAKCHE (Les Faoteurs Essentiels de L'Acclimatement du detail Europeen 

 au Tonkin. Etampes, France: Assoc. Sen. Internat. Agron. Colon., 1910, pp. 



23). This is chiefly a description of the climatic factors in Tonkin which un- 



faA-orahly affect the European breeds of live stocli. 



Physiology of man and mammals, R. du Bois-Reymond (Physiologie des 

 Mensclicn nnd der Sdugetliicrc. Berlin, 1910, 2. ed.. pp. XII+6U, figs. 139).— 

 A revised edition of a treatise written for students who wish to get a general 

 outline of the comparative physiology of man and higher animals. 



Plasm and cells. — A general anatomy of living matter, M. Heidenhain 

 (Plasma nnd Zelle. — Allgemeine Anatomic der Lehendigen Masse. Jena, 1907, 

 vol. 1, pt. 1, pp. VIII+506, figs. 276; 1911, pt. 2, pp. VI+507-1110, pi. 1, figs. 

 395), — This work is intended to serve as a foundation for the study of micro- 

 scopical anatomy. The first part of volume 1 treats of the general properties 

 of the cell and its parts, while the second part discusses in detail muscular 

 tissue and the physiology of contractilitj'. 



Each chapter is accompanied with an extensive bibliography. 



Cultivation of adult tissues and organs outside of the body, A. Carrel 

 and M. T. Burrows (Jour. Amer. Med. Assoc, 55 {1910), No. 16, pp. 1379- 

 1381). — Experiments ai'e reported on the successful cultivation of connective 

 tissue, cartilage, bone, and other tissues from various organs of dogs, cats, and 

 frogs on artificial media in a way similar to the cultivation of bacteria. The 

 importance of these results to the study of biology and pathology is pointed out. 



Tissues and organs cultivated outside the body, J. B. Huber (Sci. Amer., 

 103 (1910), No. 19, p. 359). — A popular summary of the work of Harrison ** 

 on embryonic transplantation and that of Carrel and Burrows (noted above). 



The stability of life. — A study of energetics as applied to the evolution 

 of species, F. le Dantec (La Stahilite de la vie; etude encrgctique de Vecolu- 

 tion des esp^ces. Paris, 1910, pp. 300; rev. in Ztschr. Indnktivc Abstam. u. 

 Vererbungslehre, 4 (1911), No. 3-4, pp. 293, 294). — ^A physico-chemical view of 

 life that is in accord with the transformism of Lamarck. 



" Fatness " as a cause of sterility, F. H. A. Marshall and W. R. Peel 

 {Jour. Agr. »Sc/., 3 (1910), No. J,, pp. 383-389, pi. 1).—A histological study of the 

 generative organs of 7 fat heifers. Next to the presence of lipochrome the most 

 noteworthy characteristic of the ovaries was the number of degenerative fol- 

 licles in various stages of atrophy. 



" Conclusions reached are that the derangement of the estrous cycle in fat 

 animals is caused by a disturbance of the ovarian metabolism as manifested 

 especially by a considerable deposition of pigmented fat or lipochrome in the 

 interstitial tissue, and that this process is accompanied by an unusually ex- 

 tensive degeneration of follicles which may lead to a prolonged state of steril- 

 ity. However, since the degeneration does not usually occur to any especially 

 great extent in the smaller or less mature follicles, it may be inferred that 

 the sterility so induced is commonly of a transient nature, and can be reme-
