A study of sections of tlie mannnai-y L'iand disclosed the presence of similar 

 elenients in this structure, both in the alveoli and in the various milk ducts. 

 The casts observed in the uilder are in j,M'neral very similar to the renal casts, 

 but show some characteristic features in connection with histological elements 

 of the mannnary s^land. These casts ai'e described as exudative casts of the 

 ndder. Tlie author considers that his investigations indirectly substantiate the 

 \ iew that renal casts have their origin in albuminous exudates. 



Stomatitis or sore mouth, J. Si'kncer {yiru'niUi Kht. I'ltt. UHiO, pp. 3.i-31i). — 

 Stomatitis in domestic animals may arise from a variety of causes, including 

 mechanical, chemical, thermal, and bacterial irritants. The symptoms naturally 

 vary according to the cause and stage of the disease, and the treatment must be 

 adjusted to the cause. The usual treatment consists in a change of diet, in 

 which the animal receives largely soft succulent food and the use of a mouth 

 wash, such as chlorate of potash, creolin, or carbolic acid. 



Foot-and-mouth disease, E. Leclai.nhhe (Rev. Gen. Med. Yet., 9 (1901). No. 

 97, pp. 1-9). — Statistics are given on the i)revalence of foot-and-mouth disease 

 in (Jermany, Holland. I'.elgium, Switzerland, and Hungary, from 1888 to 1905, 

 together with a brief account of the outbreak in New England. Suggestions are 

 also made regarding suitable precautionary measures to be taken in controlling 

 the disease. 



Foot-and-mouth disease in the Villette market, Vacher et at.. (BuJ. Hoc. 

 Xat. A(/r. Fniuce, (H! il'.ioii), Xo. 9, pp. 7,'/6'-?.56' ). — This is a symi)osium on the 

 danger of the spread of foot-and-mouth disease in the cattle markets. The 

 Villette market is considered as offering many ()])portnnities for the rapid 

 spreiid of foot-and-mouth disease, and stricter regulations for the control of 

 this dise.-ise are believed to be necessar.v. 



The bacteriolytic power of the blood serum of hogs, I'.. M. Rolton ( U. »S'. 

 Ihpt. A'/r.. liin: Aiiiin. IndiiH. Bill. 9'>. jip. li!. p(is. .'/). — The investigations 

 reported in this bulletin concern the reactions which take phu-e between 

 Bacillus cholera .siiis and normal and.innnune serum in hogs. Preliminary 

 experiments were made with other b.icteria. The Eluiich theory of immunity 

 is explained and illustrated for the purpose of indicating the bearing of the 

 author's investigations u|ion the utility of the theory in the study of imnumity. 



The blood used in the experiments was drawn in a sterile condition from 

 healthy hogs or from hogs in.jected from cultures of B. cholera- siii.'f. Care 

 was taken to ascertain that at the beginning of the experiments all hogs were 

 in a health.v ccmdition. The bactericidal power of the serum was tested at 

 different times by bleeding the same hog at intervals of a few days. The 

 variation in bactericidal potenc.v of the scrum is presented in talmlar form, 

 and a comparison made of the variation between venous and arterial blood 

 in this regard. 



The author sununarizes the c<mclusions drawn from his experiments as 

 follows: The bactericidal i)otency of hog serum varies from time to time and 

 ditfcrs somewhat t'<ir dilTercnt str.-iins of IS. (Iiohnr siiis. The .•ittenuating 

 effect nf lung standiuu is mure m;irkcd in some samples of serum than in 

 others under similar conditions, and the bactericidal i)ower of venous blood is 

 not always greater than that of ;irterial blood. The serum is rendered inactive
