100 EXPERIMENT STATION RECORD. 



Artificial immunity of rabbits toward anthrax, < ). Bail (( 'entbl. I la 1,1. u. Par., 1. 

 Abt.,Orig.,86 (1904), No. -'• i'l>- 266-272). — The experiment carried out by the author 

 indicates that in rabbits the leucocytes play a more important rule than the serum in 

 the production of immunity. There appeared to l>e no constant relation between 

 the precipitating and protecting power of rabbit blood with regard to anthrax. The 

 authiir describes his bacteriological methods and gives notes <>n further experiments 

 in which the serum of chickens and sheep was used in artificially immunizing rabbits 

 to anthrax. 



The occurrence of anthrax in the horse, Fkancke ( Fortschr. TV/. Hyg., .' ( 1904 ), 

 No. 3, pp. 81, 8..'). — Notes on anthrax as observed in the horse. Details are given 

 on the symptoms and pathological anatomy of equine anthrax contracted from an 

 affected cow. Infection apparently took place through a skin wound in the neck 

 region. No alterations could lie observed in the intestines. 



Generalized actinomycosis, A. Assmann (Dent. Tierarztl. Wchnschr., 12 (1904), 

 No. 7, pp. 63, 04). — Contrary to the generally accepted qpinion, the author maintains 

 on the basis of extensive statistics that generalized actinomycosis is of comparatively 

 frequent occurrence. Detailed notes are given on the clinical history and post-mortem 

 appearance of 11 such cases in cattle and hogs. From these notes it appears that a 

 great variety of parts and organs may be simultaneously affected by actinomycotic 

 lesions. 



Milk fever in cows which have not calved and the etiology of milk fever, 

 G. Meier (Berlin. Tierarztl. Wchnschr., 1904, No. 6, pp. 89-92). — An elaborate account 

 is presented of the nature of milk fever with critical references to the literature of 

 the subject. 



Detailed clinical notes are given on 5 cases of the disease in cows which had calved 

 from 4 to 8 months previously. The author states that many other such cases have 

 come under his observation. In such cases there is apparently no connection 

 between calving and the disease. The author believes that previously announced 

 hypotheses concerning the nature of milk fever must be abandoned. The idea that 

 the disease is an intoxication is combated and discarded. 



In the author's opinion the chief cause of milk fever is excessive rations of concen- 

 trated feeding stuffs. In localities in which the disease has increased most rapidly, 

 heavy feeding with grains (up to 18 lbs. per day) has been indulged in for the pur- 

 pose of increasing the milk flow. This excessive feeding may cause an unusual flow 

 of blood to the udder. The author defines milk fever as a cerebral anemia caused 

 by hyperemia of the udder and digestive apparatus. 



The beneficial results obtained by pumping air, water, or other fluids into the 

 udder are explained as due to the fact that thereby the excess quantity of blood is 

 forced out of the udder. The name cerebral anemia is suggested to replace milk 

 fever. 



Infusion of air into the udder in cases of milk fever, E. Wissmann (Berlin. 

 Tierarztl. Wchnschr., 1904, No. 9, pp. 153, 154). — The author adopted this method in 

 the treatment of 15 cases of milk fever, with complete recovery in 14 cases. Recov- 

 ery took place in periods ranging from 20 minutes to 20 hours. The most important 

 and most interesting points in the clinical history of these cases are presented in a 

 tabular form. The author believes that mammitis need never develop as a result of 

 this operation if ordinary care is exercised in cleaning the instruments and filtering 

 the air. 



Lead poisoning in cows, Dohrmann (Berlin. Tierarztl. Wchnschr., 1904, No. 5, 

 pp. 69, 70). — In most cases of lead poisoning in cows observed by the author constipa- 

 tion was present, but less often a pronounced diarrhea was observed. In treating 

 the trouble good results were sometimes obtained by administering Glauber salts. 

 Sulphuric acid, however, was most effective. Badly poisoned animals gradually
