be given per os without disturbing its activity, providing a 1 per cent solution 

 of sodium bicarbonate, some extract of opium, and a saturated solution of salol 

 in chloroform are given i hour before the antitoxin is administered. 



Seven cases of anthrax in man, E. Vollmeb {Ztsclir. Med. Beamte, 23 

 {1910), No. 8, PI). 271-276, pi. 1; abs. in CentU. BaJct. [etc.], 1. Abt., Bef., 48 

 (1910), No. 8, pp. 225, 226). — A description of 7 cases of anthrax (pustula 

 maligna) in man, which had their origin in the hides of cattle which were 

 infected with anthrax. According to the author the tanning process does not 

 destroy the spores of the anthrax bacillus. 



Malta fever in the Gard, C. Dubois {Bui. Inst. Pasteur, 9 {1911), No. 13, 

 p. 613). — This is a study in regard to the etiology, geographical distribution, 

 and pathology of this disease. Out of 195 goats examined by the lacto- or sero- 

 diagnostic methods, 13 gave positive results. Fifty-seven per cent of the cases 

 were in males. It is also pointed out that chickens can be mortally infected, and 

 furthermore, that the disease can be transmitted to man. 



Concerning the presence of the embryos of Trichinella spiralis in the 

 blood of patients suffering from trichiniasis, A. R. Lamb {Amer. Jour. Med. 

 Sci., 142 (1911), No. 3, lyp. 39o-.',02, fig. 1). — "In the examination of the blood 

 sediment for the embryos of T. spiralis we have a valuable means of diagnosis in 

 cases suggesting trichiniasis. . . . 



" The technique of the examination is very simple. While the search for the 

 embryos is tedious, it is scarcely more so than the examination of the blood for 

 the Plasmodium of malaria. The earliest time at which the embryos may be 

 found in the blood is on the sixth or seventh day after infection. The latest 

 date is not accurately fixed. While the parasites have not been found later than 

 the twenty-seventh day after infection in guinea pigs, or later than the twenty- 

 second day after the onset of symptoms in man, there is some ground for the 

 belief that they may occasionally be recovered in the fifth or possibly the sixth 

 week after infection." 



The identifi-cation and classification of trypanosomes of mammals, A. 

 Laveran (Ann. Inst. Pasteur, 25 (1911), No. 7, pp. Ii97-517, fig. 1 ; abs. in Sleeping 

 Sickness Bur. [London] Bui, 3 (1911), No. 30, pp. 356-360).— A study of the 

 identification and classification of trypanosomes of mammals. 



Further investigations of trypanosomes of cattle in the District of Upper 

 Westerwald, together with a contribution to the knowledge of parasitic 

 flagellates of blood-sucking flies (Tabanus and Haematopota) in Germany, 

 P. Knuth and G. Rauchbaae (Ztsclir. Infelctionskrank. u. Hyg. Hausticre, 8 

 (1910), No. 2-3, pp. l-'i0-15.'i, pis. 2; abs in Sleeping Sickness Bur. [London] Bui., 

 2 (1910), No. 21, p. 371). — The authors find Trypanosoma franki to resemble 

 closely, or be identical with, T. tJieileri. The flies examined were mostly 

 Tlwmatopota pluvialis and in a few instances species of Tabanus. The technique 

 of the examination is described and a bibliography of 21 titles is appended. 



The resistance of goats and sheep to trypanosomiases; the long duration 

 of acquired immunity following these diseases, A. Laveran (Compt. Rend. 

 Acad. Sci. [Paris], 152 (1911), No. 2, pp. 63-66; abs. in Sleeping Sickness Bur. 

 [London] Bui, 3 (1911), No. 25, pp. 126, 127). — The author calls attention to 

 the fact that while both sheep and goats are susceptible to most of the try- 

 panosomiases these infections usually take light forms which end in recovery, 

 whereas in most other animals they usually terminate fatally. The symptoms 

 are little marked ; at the beginning there are often febrile attacks but unless the 

 temperature is taken regulai'ly these in most cases pass unnoticed. 



Acquired immunity lasts a long time in both the sheep and goat. In one 

 instance the immunity of a goat to Trypanosoma evansi continued 2 years^nd 

 4 mouths. A similar instance is given of a sheep immunized successively to
