anaphylactic. This was, however, not the case when a reinjeotion of alkali or 

 acid albumin was given. When the guinea pigs were sensitized with acid 

 albumin and reinjected with all^ali albumin and dialized serum, 100 per cent of 

 them became anaphylactic. Only 50 per cent became anaphylactic when acid 

 albumin was reinjected. 



The work is being continued. 



Is eclampsia the result of anaphylaxis, J. Fellandee {Ztschr. Geburtsh. ti. 

 GynakoL, 68 (1911). No. 1, pp. 26~.'t6; abs. in Zentbl. Blochem. u. Biophys., 11 

 {1911), No. 23, p. 95If). — Guinea pigs could not be sensitized with placental or 

 fetal extracts or with milk from the same animal. It was also not possible to 

 sensitize passively a guinea pig with eclampsia serum against the amniotic 

 fluid of placental extract of man. # 



Pure cultures of aniebae parasitic in mammals, Anna W. Williams {Jour. 

 Med. Research, 25 {1911), No. 2, pp. 263-283). — "Successive pure cultures of 

 certain strains of parasitic amebse may be easily obtained by using as food 

 sterile brain, liver, or kidney tissue freshly removed from the normal guinea 

 pig, rabbit, or dog. Morphologically the individual amebae in these cultures do 

 not differ essentially from those of the same species growing in the intestines of 

 mammals. Certain characteristics, namely, large size, marked motility, clearly 

 differentiated and highly refractive ectoplasm, nucleus poor in chromatin and 

 situated near periphery of eudoplasm, endoplasm showing 2 or more vacuoles 

 and containing 2 too many red blood cells, which as a whole have been pro- 

 nounced by others to be of use in differentiating pathogenic from nonpathogenic 

 forms in the human intestines, have been shown by this study to be possessed 

 by 2 species of ameb^ in pure culture, one at least, in all probability, non- 

 pathogenic for man. Hence the diagnostic worth of these points is rendered 

 doubtful. Freshly removed tissue as food for amebse promises to be of aid in 

 obtaining pure culture of these organisms from cases of amebiasis, especially 

 from bacteria-free amebic abscesses. Pure cultures of amebse may be of use 

 in helping to detect specific micro-organisms in Infectious diseases of unknown 

 origin." 



A bibliography of 20 titles is appended. 



The parasitic amebas of man, C. F. Craig {Philadelphia and London, 1911, 

 pp. X-\-253, pis. 18). — This work describes in detail the parasitic amebse found 

 in the human body and discusses the life cycle of each species, its distribution in 

 the body, and its relation to disease. 



In regard to the technique of Ascoli's precipitation reaction for detecting 

 anthrax, A. Ascoli {Berlin. Tierdrztl. Wchnschr., 27 {1911), No. 22, pp. 889, 

 390, fig. 1). — This method, which the author terms the thermo-precipitation 

 method, consists of extracting the suspicious material with a physiological salt 

 solution by boiling and then testing it against a specific precipitating serum. 



The apparatus used for the purpose is illustrated and described in detail. 



Arteriosclerosis in animals and its relation to arteriosclerosis in man, 

 C. Otto {Arch. Path. Anat. u. Physiol. [Virchow], 203 {1911), No. 3, pp. 352- 

 J/OJi, pi. 1). — The results of this histological study, which was made with digalen, 

 adonidin, and strophantin on rabbits and dogs, show that the changes in the 

 blood vessels of animals are equivalent to those which appear in sclerosis of 

 the vessels in man and have the same etiology. The pathological changes noted 

 in the animals under observation were not absolutely identical with those found 

 in man, but the author believes this to be due to the peculiar construction of 

 the arteries of the animals, the amount of substance required to produce the 

 changes, and the time of exposure. 



Some work with alcohol and nicotin will be reported on later. A large 

 bibliography is appended.
