and those hore reported, it is found that cattle vary greatly in susceptibility to 

 cattle plague. In India the cattle on the plains are resistant, while those on the 

 mountains are highly susceptible. Philippine cattle from noninfected districts 

 are highly susceptible and the carabao appear to be more resistant than the 

 Batanes cattle. Cattle imported from Indo-Chiua are highly resistant to cattle 

 plague. 



Ephemeral fever or three days' sickness in cattle, G. W. Freer {Vet. Jow., 

 66 {1910), No. JflB, pp. 19-22). — A general account of this disease. Its trans- 

 mission in nature is thought to be through the agency of mosquitoes. Ex- 

 periments conducted with ticks have resulted negatively. Although in a large 

 percentage of cases one attack confers an immunity for a considerable time, 

 the author has known of numerous cases where cattle hnve had 2 or 3 o'- ^"eu 4 

 attacks. 



Accidental parasitism of the udder, G. AIoussu {Rec. Med. V^t., 87 {1910), 

 No. 1, pp. 5-11, figs. 2). — The author presents what he considers to be the first 

 report of an invasion of the bovine udder by an animal parasite. The case 

 reported is one in which during the course of milking small maggots appeared 

 in the milk. These have been identified as chironomid larvre. It is concluded 

 tliat the larva? must have entered through the milk duct. 



A disease of sheep in Tasmania, J. A. Galruth {Vet. Jour., 66 {1910), 

 No. .'{19, pp. 25Jt-265). — An extremely fatal braxy-like disease of sheep which 

 appears annually in certain districts of Tasmania is here described under the 

 name of malignant transudation. It is characterized by an intense toxemia 

 or general poisoning of the animal's system by means of the toxic products 

 elaborated by the specific micro-organism, which has been designated as 

 Baeilhis transudationis maligncc. This bacillus forms resistant spores and 

 thus is able to retain its virulence in the soil for a long period. The bacilli 

 may gain entrance to the system of the sheep either by means of skin punctures 

 or through abrasions in the lining membrane of the alimentary tract. It is 

 most commonly seen during August and, September, but may appear earlier 

 in the year, and seems to be definitely associated with the spring growth of 

 young grass. 



As the common source of infection is from the ground, preventive measures 

 consist of the destruction of carcasses and the removal of lambs from infected 

 pastures during the danger season of the year. It has been found that sheep 

 display no definite immunity to experimental inoculation with the specific 

 micro-organism during the summer months. 



Tuberculosis of hogs and how to control it, J. It. Mohler ( JJ. S. Dept. Agr. 

 Yearbook 1909, pp. 227-238, pis. 3). — Substantially noted from other sources 

 (E. S. R., 10, p. 199; 20, p. 982). 



Hog cholera, R. A. Craig and II. H. Madaus {Tndinitn »S7rt. Bui. I'fO, pp. 

 I27-I6.'i, figs. 12). — This account of hog cholera and the methods of immuniz- 

 ing swine against it Includes a report in tabular form of experimental work 

 with cultures from the tissues of cholera hogs and blood filtrates, which has 

 been carried on during the course of outbreaks that have occurred in Indiana 

 in the last 3 years. 



Of cultures made during 10 different outbreaks, 4 were Bacillus coil com- 

 inunis, 5 were B. eiioicrw suis, and 1 was a Micrococcus. " p]ighteen of the 

 30 cultures made from the tissues of experimental hogs that contracted the 

 disease by inoculation and exposure in the pens were B. cholera! suis and 12 

 were B. coli communis. Blood from cholera hogs collected in test tubes under 

 proj^r aseptic precautions, and incubated for several weeks, showed no organ- 

 isms in a large percentage of cases. These animals contracted the disease by
