Effectsofiodid of potash as an injection in the mammary gland, P. Couremaxs 

 {Ann. Med. TV/., 4'' {1900), No. 5, pp. 240-243). — A description is given of the usual 

 method for making intramammary injections of this substance. Experiments were 

 conducted for the purpose fif determining Avhether oxygen compounds of iodin were 

 contained in the commercial iodid of jtotash. It was found that such compounds 

 ■were not present. 



Infectious pneumonia of calves, Sauer ( Wcltuschr. Thierheilk. u. Viehzucht, 45 

 {1901), No. 12, jip. 133, 134) ■ — Brief notes on outbreaks of this disease. After 

 thorough disinfection of the j^remises no more cases of the disease developed. 



Thrush in cattle, Hajnal {Berlin. Thierarztl. Wchnschr., 1901, No. 9, pp. 153- 

 155) . — The author calls attention to the difficulties of differential diagnosis between 

 infectious foot-and-mouth diseases and other forms of cattle diseases which are 

 included under the term thrush. It is stated that stomatitis aphthosa, oidica, and 

 diphtheritica are readily distinguished from infectious foot-and-mouth disease when 

 a number of cases are to be had for observation and when the history of cases can 

 be obtained; but that diagnosis is uncertain when based upon a brief inspection of 

 an infected animal. 



Foot-and-mouth disease and sanitation, E. Thierry {Jour. Agricole [Paris], 

 12 {1901), No. 131, pp. 29-32). — A general discussion of the efficiency of various 

 sanitary methods in preventing the spread of this disease. 



Suspicion of infection with foot-and-mouth disease in the sense of the 

 inspection regulations, Eeuter {VrtJjschr. Bayer. Landw. Batli.es., 5 {1900), No. 4, 

 SujK, j)p. 641-653). — The author presents a general discussion of the lequirements of 

 the law concerning tliis disease and of the accuracy of ^phraseology. 



Analyses of hog-cholera remedies, E. W. Thatcher {Nebraska Sta. Bpt. 1900, 

 pp. 70-72) . — xinalyses are reported of 5 i^reparations sold in the State as remedies for 

 hog cholera. 



Diagnosis of rabies in dogs by microscopic examination of the nerve gan- 

 glia, G. Hebrant {Ann. Med. Vet., 49 {1900), No. 6,p>p. 302-309) .—Ch&ngei^ in the 

 nervous tissue were especially well marked in the gasserian ganglia in cases of rabies. 

 The ganglia of the left side were rather more acutely attacked than those of the right. 



The agglutination of Staphylococcus aureus by the serum of vaccinated 

 and infected animals, J. Nicolas and C. Lesieur {Compt. Bend. Soc. Biol. Paris, 

 53 {1901), No. 4, pp. S7-89) . — The authors studied the influence of serum from an 

 immunized goat upon cultures of this organism which were already developed and 

 upon those which were in the process of development. Other experiments were also 

 made in the agglutination of other species of Staphylococcus. The serum of rabbits 

 and guinea pigs was tested with refereijce to the agglutinating power. From their 

 experiments the authors conclude that the serum of goats inmumized by means of 

 repeated hypodermic injections of cultures of Staphylococcus aureus causes an aggluti- 

 nation of this organism, Imt that the serum of animals suffering from an acute infec- 

 tion from the same organism possesses no agglutinating power. 



The histogenesis of malignant tumors, Schijtz {Ztsckr. Veterindrk., 13 {1901), 

 No. 3, pp. 101-117). — An elaborate discussion of this subject, with a critical review 

 of the literature and a bibliography. 



On disinfection, W. L. Mackenzie ( Vel. .Jour., n. ser., 3 {1901), No. 15, pp. 141- 

 150). — The use of formalin for disinfection is discussed in detail, and notes are given 

 on methods of applying disinfectants to surfaces, including disinfection by free gas, 

 by moist brushing or rubbing, jet, or shower, and Ity spray.
