Report of the Department committee on the Federal meat-inspection serv- 

 ice at Chicago, J. 11. Moiilkk. II. P. Steddom, and G. V. McCabe (U. S. Dcpt. 

 Agr., Bid: Aiiini. Iiidtis. Rpt. 1906, pp. //06-//56). — A detailed description is given 

 of the Federal ante-mortem meat-inspection service, post-mortem inspection of 

 meat, State and municipal inspection of meat in Chicago, Government super- 

 visit>n of canned products, the sanitary condition of various abattoirs and pack- 

 ing houses, and the legal phases of the question, including the scope of authority 

 now possessed by the Federal, State, and municipal authorities. 



The cure of experimental nagana, F. Loeffi.ek and K. Runs (Dcut. Med. 

 Wclnischr., 3.J (I'lOl), .Yo. J.}, pp. 1361-1366). — Several experiments have shown 

 the value of atoxyl, trypanrot, and other substances in the control of try- 

 panosomiases. In experiments with guinea pigs, rats, and rabbits it was found 

 possible to protect these animals against repeated infection and to cure serious 

 cases of the disease by the use of atoxyl. In the authors' experiments, arseni- 

 ous acid is used and this substance is considered a specific against try- 

 panosomes. Its curative effect is manifested promptly whether it is admin- 

 istered by way of the mouth, in the blood circulation, or in the peritoneal 

 cavity. Beneficial results, however, are obtained only when the drug is given 

 in a systematic manner, in the proper doses, and at the proper intervals. 



According to the authors, it appears that the fatal dose is about one-third 

 larger than the curative dose. It is recommended that the remedy be admin- 

 istered at 5-day intervals. 



Anthrax in Arkansas, R. R. Dinwiddie (Arkansas Sia. Bill. 96, pp. 91- 

 112). — A general account of the nature of anthrax is given by the author. 

 During 1905-6 a serious outbreak of this disease occurred in certain parts of 

 Arkansas. Horses and mules were more frequently attacked than other animals. 

 The disease appeared to depend for its distribution upon swampy, overflowed 

 lands and the agency of insects and infected fodder. Anthrax may be con- 

 trolled by the destruction and cremation of affected animals, bui-niug of infected 

 pastures, and plowing and cultivating infected fields. Vaccination is recom- 

 mended as being of some value, although it is contended that much of the 

 commercial vaccine available for use against anthrax is too weak or at least 

 ineffective. 



Anthrax and anthrax vaccines, R. R. Dinwiddie (Arkansas Sta. Bill. 97, 

 }tp. tl3~13.i). — The conuuercial vaccines available in this country were tested 

 by the author for the purpose of determining their effectiveness or the causes 

 of failure in using them. It was found that anthrax blood becomes sterile if 

 dried on paper for 4 or 5 days. Anthrax bacilli in horseflies and cattle ticks 

 do not form spores, but soon lose their vitality. According to tests made on 

 laboratory animals anthrax blood sterilized by desiccation has no protective 

 value as a vaccine and in general no immunity appears to be conferred by vacci- 

 nation with sterilized cultures. It was found that the commercial anthrax 

 vaccines obtainable in this country contain attenuated anthrax bacilli, but 

 that they are inefficient either on account of age or of overatteuuation. 



Some observations on rabies, E. C. Schroeder (TJ. 8. Dept. Agr., Bur. Anim. 

 Indus. Rpt. 191)6, pp. lHl-196; Circ. IZO, pp. 16).— The discussion of the sub- 

 ject of rabies provokes considerable antagonism from certain dog fanciers 

 who are disposed to doubt the existence of the disease, but, according to the 

 author, the evidence proving the distinct and specific nature of rabies and the 

 high mortality which it causes is sufficient to convince the unprejudiced ob- 

 server, and there appears to be no fouudatiou for the somewhat prevalent
