different occasions without responding. A careful post-mortem examination was 

 made on eacii of these animals with the result that they were found to be tuberculous. 



Tuberculosis in horses, Rabe {Ztschr. Fleisch. u. Mikhyg., 11 {1901), No. 8, pp. 

 S42, 24s). — Detaileti notes are given on the symptoms and the post-mortem findings 

 in cases of tuberculosis in the horse. 



Anthrax infection, L. Heim {Arch. Hi/g., 40 {1901), No. 1, pp. 55-62). — The 

 author observed that in preparations of anthrax bacilli stained with Loffler'a metha- 

 lyne blue, a capsule or membrane was differentiated in color from the remainder of 

 the bacilli. The color of the capsule when stained by this method was a clear rose. 

 This behavior of the anthrax bacilli was made use of in differential diagnosis between 

 anthrax and other diseases and in making a diagnosis in suspected cases of anthrax. 

 When this method is applied, rose-colored patches are seen in blood and in exuda- 

 tions which do not contain pus. In diseased tissue which contain the organisms of 

 hog cholera, fowl cholera, and bubonic plague the rose color was not observed after 

 the stain had been applied, and the author believes that this staining procedure 

 offers a reliable method for diagnosing anthrax in diseased tissues. 



Experiments on the curative action of anthrax serum, A. Sclavo {Berlin. 

 Klin. WcJinschr., 38 {1901), No. 18, pp. 481-484- — The author first obtained satisfac- 

 tory results with a curative anthrax serum from experiments on rabbits and sheep. 

 Frord the sheep a serum was obtained which completely protected the rabbits against 

 anthrax, although they had been inoculated 12 hours previously with an anthrax 

 culture containing spores. It was found that different sheep reacted verj' differently 

 to the preliminary treatment designed for the protection of the curative serum. In 

 many cases, even when the doses of attenuated cultures were gradually increased 

 to large size and were continued for a long time, these sheep ix)ssessed very weak 

 protective power. The difference in the strength of the serum obtained b)^ this 

 method did not depend on the age, breed, or sex of the sheep, but appeared to be a 

 peculiarity of the individual sheep. In some of the sheep which had been immu- 

 nized against anthrax the author administered pilocarpin in order to determine 

 whether the protective properties of the sermn could be strengthened in that manner. 



A study of actinomycosis, V. E. Mertexs {Centbl. Bakt. u. Par., 1. Abt., 29 

 {1901), No. 16, pp. 649-654)- — Since several authors had classified actinomyces into 

 2 species, of which one was supposed to be virulent and the other not, and one 

 aerobic and the other anaerobic, a special study of the matter was taken up by the 

 author for the purpose of gaining new evidence on this point. Material containing 

 the actinomyces organism was subjected to different conditions until from the 

 original material which came from one source the 2 suggested species were obtained. 

 The organism at the beginning of the experiments was grow'ing at a temperature of 

 37° C, and was disposed to be anaerobic, but it was found possible to obtain aerobic 

 actinomyces from this source which developed readily at much lower temperatures. 

 The author made experiments on animals, by which it was determined that both 

 forms of the actinomyces were jiathogenic, although the anaerobic form seemed to 

 possess the greater virulence. It is believed from these experiments that there is 

 but one species of actimimyces. 



Some results in the treatment of milk fever by the method of Schmidt- 

 Kolding, I. A. Eilek {Berlin. TierilrzK. Wrhnschr., 1901, No. 17, pp. 261, 262).— In 

 this article statistics are brought together in 803 cases of milk fever which were 

 treated with potassium iodid. Of the 803 cases, 615, or 76.6 per cent, recovered com- 

 pletely, while the others were slaughtered or died. The crisis of the disease in 350 

 cases came after 24 hours and in 68 cases after the second or third day. The body 

 temperature at the outbreak of the disease was usually between 37 and 38.5° C, but 

 varied from 36.4 to 41.5° C. As a rule but one dose was given, and this varied from 

 5 to 12 gm.
