A study of five members (or so-called species) of the septicemia hemor- 

 rhagica (Pasteurella) group of organisms with special reference to their 

 action on the various carbohydrates, A. M. Besemeb (Jour. Bact., 2 {1917), 

 No. 2, pp. 177-184 ) . — " The members of the septicemia hemorrhagica group 

 studied were practically uniform in their biochemical actions. The passing of 

 an organism through a rabbit did not change its biochemical characters, ex- 

 cept to a very slight degree." 



The virulence of apparently sound muscle and lymph glands in general 

 bovine and porcine tuberculosis, P. Chauss6 (Ann. Inst. Pasteur, SI {1917), 

 No. 1, pp. 1-18). — The literature on the subject is reviewed and data submitted 

 in tabular fonn. 



In the original study reported material from 18 tubercular hogs and 40 tuber- 

 cular cattle was used. Extracts were made of the muscular and lymphatic 

 tissue and injected into guinea pigs. Of the animals injected with the ma- 

 terial obtained from the muscle tissue none exhibited tubercular symptoms or 

 lesions on autopsy. These results indicate the freedom from virulent material 

 of the muscles of animals which have died from the disease. Of 53 samples 

 of lymphatic material 13 were found to be virulent. The relative frequency 

 of the virulence of this material is considered to be strong proof of the r61e 

 of filtration of the lymphatic system as a defensive agency. 



The results of the investigation are discussed and their hygienic importance 

 emphasized. 



Eupatorium ageratoides, the cause of trembles, R. S. Cuetis and F. A. 

 Wolf {U. S. Dept. Agr., Jour. Agr. Research, 9 {1917), No. 11, pp. 397-404, pis. 

 3). — This is a progress report of investigations conducted at the North Carolina 

 Experiment Station, in the mountainous sections of which State considerable 

 losses of domestic animals result from a malady known as trembles. The 

 disease is thought to be transmissible to man through milk products or flesh 

 of animals affected with the disease, and is known by physicians as milk 

 sickness. 



The report is summarized as follows : " E. ageratoides, commonly known as 

 white snakeroot and locally known in North Carolina as richweed, had previ- 

 ously been claimed by Moseley [E. S. R., 21, p. 383] to cause trembles in ani- 

 mals. This claim has been substantiated by experiments with sheep in which 

 green plants of E. ageratoides were fed during the months of June, July, 

 August, September, and October, 1916. Fifteen cases of trembles in sheep have 

 been developed from feeding E. ageratoides. Fourteen of these resulted fatally 

 and one of them recovered. Death of one of these sheep was probably due in 

 part to an infestation of stomach worms. Death resulted in from 5 to 27 days 

 following the beginning of feeding of E. ageratoides. Considerable variation 

 existed in the several ewes, also, with reference to the quantity of weed ingested 

 before trembles appeared. 



" Indirect evidence against the infectious nature of the disease was secured 

 by failure to communicate trembles from sheep characteristically affected to 

 healthy sheep when they were confined and fed together in a small lot. 



" Salt and soda in the amounts given along with a ration of grain and 

 E. ageratoides were without apparent antidotal effect. No harmful effect fol- 

 lowed the feeding for 69 days of aluminum phosphate mixed with grain and 

 supplemented with alfalfa hay."
