The bacillus of tuberculosis, K. A. dk Schweinitz [V. S. Depl. Agr., Bureau of 

 Ani)iial Iiahixlnj Jipt. H/00, jip. ^6::!-^80). — This paper was read l)efore the section of 

 bacteriology and parasitology of the Thirteenth International Medical Congress held 

 in Pf-ris August 4 to 10, 1900. The author gives a general discussion of the source of 

 infection with tuberculosis, varieties of tubercle bacilli, distributi(jn and diagnosis of 

 the disease, bovine tuberculosis, the relationship between bovine and human tuber- 

 culosis, and the treatment of the disease. On the last-named subject the author 

 mentions details concerning various forms of treatment which have reeentlj' been 

 advised for controlling tuberculosis in man. 



The free distribution of blackleg vaccine, V. A. NoK(i.\.\Kn [V. S. Dept. Agr., 

 Burenii uf Anhnul Lidiifftnj Rpt. i: 00, pp. 35-51, figs. 4)- — During the fiscal year 1900 

 the Bureau of Animal Industry prepared and distributed 1,076,150 doses of blackleg 

 vaccine among 6,142 stockmen in 40 States and Territories. The region which is 

 worst infected with blackleg is the area between the ]\Iissi.ssippi River and the Rocky 

 Mountains, extending from Canada to the Gulf of Mexico. Among the Eastern 

 States Virginia seems to be the only one in which the disease prevails to a serious 

 extent. The disease has gradually increased in extent since stockmen began to 

 improve native breeds and replace them with modern breeds of a less active nature 

 and of a decreased resisting power to disease. Reports were received from 1,980 

 cattle owners, concerning 369,258 head of stock. The total amount of loss from vac- 

 cination was 0.69 per cent, but allowing for mistakes in vaccination, the loss is esti- 

 mated at 0.55 per cent. Quotations are given from a number of letters written l)y 

 jirominent stockmen who used blackleg vaccine to a greater or less extent. 



The Thirteenth International Medical Congress, E. A. de Schweixitz {U. S. 

 Dept. Agr., Bureau of Auunal Industry Rpt. 1000, pp. 254-359). — A brief report of the 

 proceedings of this Congress which met in Paris in August, 1900. During the sessions 

 of the Congress more than 6,000 physicians from different countries were present, and 

 the United States was third on the list in the number of members. Brief notes are 

 given on some of the more important papers which were read during the meetings; 

 these include discussions of toxins and antitoxins, tuberculosis, and malaria. 



On the morphology of the anthrax bacillus, A. Hixterbekgek {Centhl. Ikikt. 

 n. Par.. 1. Aht., SO {1001), Xo. 11, j)j>. 417-424, pi l,fi(l- !)■ — The author was able to 

 demonstrate clearly the capsule of the anthrax bacillus, by means of the silver- 

 staining method of Van Ermengem. The clear double contour lines of the capsule, 

 Avhen treated in this manner, indicate that the capsule is to be considered an integral 

 part of the bacillus and not a product of treatment by artificial methods. Besides the 

 well-known capsule of the anthrax bacillus, the author described a much larger and 

 broailer membrane, of less definite character. The latter membranes are not pro- 

 duced l»y swelling of the capsule i)roper, l)ut seem to be a distinct part or organ of 

 the body of the bacillus. An elaborate method was devised for the demonstration 

 of threads connected with the body of the anthrax bacillus. AVhile it was not 

 definitely determined by the author that these threads in all instances stand inorganic 

 union with the bacillus, the evidence points in that direction, and it is suggested l)y 

 the author that the threads should be called mycelia and treated as homologous with 

 the mycelia, or vegetative portion of higher fungi.

 tions? R. Si.LPSKi ( ( •< nthl. linkt. u. Par., 1. Aht. ,30 (1901 ), Xo. 10, pp. 390-400, figs. 2).—
