the last stages of the disease, at a time when it contains no hemolytic comple- 

 ment, has no inhibitory effect npon the activating power of the complement 

 of normal serum. The presence of numerous Irypanosomes in the blood causes 

 of itself no diminution of the hemolytic complement, and secondly it is not 

 possible to absorb, in vitro, the complement from normal serum by the addition 

 of numerous trypanosomes." 



The seminal vesicles as carriers of infection, R. H. J. Gallandat-Huet 

 (Centbl. Bald, [etc.], 1. AM., Orhj., 52 {1909). No. J,, pp. Jf77-J,97 ; ofts'. in Vet. 

 Rcc, 22 (1910). No. 1133, pp. 630, 631). — Studies made of the seminal vesicles 

 of a number of animals, including the horse, bull, ram, goat, etc., show that 

 micro-organisms may be carried in this way by healthy animals. The secretion 

 of seminal vesicles of animals that had died of acute septicemia was found to 

 contain the specific organism. It was found that the virus might be transferred 

 in the act of coition. Experiments in which the disease was artificially pro- 

 duced in small experimental animals showed that the virus lingers in the semi- 

 nal vesicles after it has apparently disappeared from the circulation and from 

 the parenchymatous organs.

Condemned animals and bacteria in the flesh, of animals slaughtered under 

 such conditions, A. Metzger (Uber Notschlachtungen und Bakterien im Fleische 

 notgcsclilachteter Tiere. Inaug. Diss., Univ. Bern, 1909, pp. 72). — A large 

 amount of statistical and other data are summarized and investigations reported 

 regarding the character and extent of bacterial infection in the flesh of animals 

 condemned as diseased, but which under certain restrictions may be slaughtered 

 and sold in Germany for food purposes. 



According to the author, the bacteria which may exist in the flesh of such 

 animals and cause disease belong to the colon-typhoid group. According to his 

 summary, 13 per cent of the condemned animals slaughtered under general 

 methods of inspection in Alsace-Lorraine in 1907 were declared unflt for human 

 food, owing to the possibility of bacterial contamination, and 19 per cent in 

 Schleswig-Holstein where bacterial insi^iection was in force. He believes that by 

 microscopical inspection alone a larger proportion of meat than is necessary 

 may be withheld from sale, and recommends systematic bacteriological studies 

 which will result in a better knowledge of the whole subject, so that the inspec- 

 tion may be regulated in such a way as to conform to the demands of public 

 hygiene and yet not work undue hardship to the meat industry. 



Concerning' a so-called septic condition in slaug'htered animals and its 

 relation to meat poisoning and bacteriological methods of meat inspection, 

 M. MxJLLER (Ztschr. Fleisch u. Milclihyg., 20 {1910), No. 5, pp. 7.'/5-J.57).— From 

 a summary and digest of data the author concludes that bacteriological studies 

 are essential in the case of animals condemned as diseased, since where the sale 

 of such animals as food is permitted the flesh may more or less frequently cause 

 illness through bacterial infection of a specific character.

Pseudotuberculosis in guinea pigs produced by Bacillus paratyphosus B., 

 Dieterlen (Arh. K. (Isndlitsamt., 30 [1909), No. 2, pp. .'/2.9-',,^J).— The author 

 finds that pseudotubercular lesions of the spleen can be produced in guinea pigs 

 through the subcutaneous injection or the ingestion of Bacillus paratyphosus B.
