antigen, the authors believe that it is the equal of any of the antigens proposed 

 by others and that it has the advantage of being sterile and stable, and possibly 

 more sensitive. 



Vesicular stomatitis of horses and cattle, J. R. Mohlee {Jour. Amer. Vet. 

 Med. Assoc, 52 (1918), No. 4, pp. 410-422) .—This paper, presented at the 1917 

 meeting of the American Veterinary Medical Association, at Kansas City, Mo., 

 Includes later data than those previously noted (E. S. R., 37, p. 81). 



Researches upon abortion of cattle, W. L. Williams (Rpt. N. Y. State Vet. 

 Col., 1915-16, pp. 117-198, figs. 9). — In this discussion, which is in continuation 

 of reports previously noted (E. S. R., 38, p. 183), the author considers the 

 avenue and date of intrauterine infection, the immunity of contagious abor- 

 tion, researches in a large dairy herd, the influence of copulation and other 

 agencies upon the agglutinating power of the blood, and diseases of newborn 

 calves. An outline of recommendations for control is included. 



A preliminary study of the pathology and bacteriology of ovaritis in 

 cattle, C. P. Fitch (Rpt. N. Y. State Vet. Col., 1915-16, pp. 199-208) .—This is 

 a preliminary report of investigations under way which have led the author to 

 consider the following tentative conclusions justified : 



" Cystic degeneration of the ovaries of cattle is common. The character of 

 the cysts is often simple, but cystic corpora lutea or ' hemorrhagic cysts ' are 

 found. Adenocystoma and papillomatous and carcinomatous cysts are rela- 

 tively uncommon. Cultures made from cystic ovaries of cattle show a variety 

 of organisms to be associated with this condition." 



The vaccine treatment of Texas fever, R. L. Rhea (Vet. Notes, 11 (1917), 

 No. 1, p. S). — The successful treatment of two cases of Texas fever by the use 

 of a combined streptococcus and staphylococcus vaccine is recorded by the 

 author. 



The etiology and mode of infection in white scours of calves, W. A. Hagan 

 (Cornell Vet., 7 (1917), No. 4, pp. 263-283) .—A summary of the present status 

 of knowledge of this disease. 



Investigations have shown that " a large percentage of calves are born with 

 infected meconium. Bacillus coli and certain cocci are the organisms found. 

 The same organisms are found in the fetal fluids and utero-chorionic space in 

 the sealed uteri of apparently normal cows. The utero-chorionic space is first 

 infected, followed by the fluids and lastly, the meconium. The infection reaches 

 the meconium by swallowing of the amniotic fluid by the calf. The infection 

 probably reaches the utero-chorionic space by passing through the cervix uteri 

 from the vagina before the seal is formed, and persisting there throughout 

 pregnancy. 



" The infection frequently existing in the intestine of the unborn calf some- 

 times produces scouring before birth, but usually induces an acute toxic condi- 

 tion with diarrhea soon after birth. These diarrheic feces are highly virulent 

 to other calves. Ordinary disinfection is insufficient to deal with this disease 

 because of the number of calves born with the infection contained within them. 

 These calves will develop tlie disease despite the most rigid disinfection of their 

 surroundings and care used with their food." 



Hog' cholera in Argentina, F. Rosenbusch, J. Zabala, and R. Gonzalez 

 (An. Soc. Rural Argentina, 51 (1917), No. 9, pp. 657-665, pis. 7, figs. 5).— This 

 is a discussion of the nature and occurrence of hog cholera in Argentina. 



Trichinosis in Denmark, J. Fibiger (Hospitalstid. [Copenhagen'^, 60 (1917), 

 No. 42, pp. 1021-1048; abs. in Jour. Amer. Med. Assoc., 69 (1917), No. 26, p. 

 2212). — The author points out that meat from a single hog infested with
