Twenty-three of these tows produced ii'uorinal calf an average of 401 days 

 subsequent to abortion, conception taking place practically 6 months after 

 jiborting. Experience indicates that it is useless to attempt to breed a cow 

 for 4 or 5 mouths subsequent to aborting. To the yeast treatment is attributed 

 in part the success in inducing conception following premature delivery. 



The diagnosis of chronic forms of niammitis in cows by means of the 

 method of Trommsdorff, H. Martkl (//;/(/. Viande et Lait. 2 {190S). Xo. .'/, pi). 

 161-165). — A test of the Trommsdorflf method for the identification of leucocytes 

 indicated that this method can not be relied on exclusively in the diagnosis of 

 niammitis without a veterinary examination of the suspected cows. 



Aphthous pseudostomatitis of cows, Lienaux (Ann. Med. Vet., .77 (/.90,S). 

 \<>. 'i. pp. /8J-/.''.?). — Various investigators have studied the symptoms and 

 liathology and attempted to determine the etiology of stomatitis In cattle with 

 synii)tonis resembling foot-and-mouth disease. It is believed that the ma.iority 

 of cases of stomatitis of this form are due to a fungus or bacterial cause which 

 produces an infection more readily after the mucous membrane has become in- 

 jured or irritated by drugs or from other causes. 



Texas fever, L. L. Lewis (Oklahotna Sta. BiiJ. 81, pp. 3-32, figs. i9).— This 

 bulletin includes a general discussion of Texas fever in which particular atten- 

 tion is paid to the life history, habits, and methods of eradication of the cattle 

 tick. The author considers $750,000 to ii;i,(X)0.000 to be at the present time a 

 ^low estimate of the annual loss in Oklahoma due to this tick. In addition to 

 21(ini(irfjpii!s anniilatiis, the castor-beau tick, the net tick, the dog or wood tick, 

 the lone-star tick, and the ear tick (Ornithodoros mcgnini) are described as 

 parasites of cattle in Oklahoma. 



While cattle may become immune to a certain degree of virulence of Texas 

 fever infec-tion, it is stated to be a common experience in many portions of 

 Oklahoma for them to contract the disease when ticks from cattle shipi>ed from 

 farther south attach to them. In this way a great many cattle are lost every 

 sunuuer on account of the more virulent form of infection brought into the 

 pa.stures and ranges. The methods of eradicating the cattle tick are describetl 

 and plans are given for the construction of a dipping vat. 



Poisonous symptoms after feeding peanut meal (lUus. Landw. Ztg„ 2S 

 (1908), Xo. 21), pp. 259, 200). — A few cases of poisoning have been noted from 

 the effects of feeding peanut meals which have been adulteratetl or have become 

 contaminated with molds or other injurious materials. The symptoms in one 

 case included diarrhea, loss of appetite, diminution of milk yield, and fever. 

 The ]ieanut meal which caused these effects in cows was found to contain a 

 small, quantity of castor-oil beans. 



The bacillus of Preisz-Nocard in ovine pathology, H. Carre and L. 

 BiGOTEAU {Rri: Gen. Med. Yet., 11 (1908), Xos. 127. pp. 369-380; 128, pp. 433- 

 ■i-'i9). — The bacillus of Preisz-Nocard has been studied by a number of investi- 

 gators with particular reference to the details in the pathological lesions which 

 it produces and the criteria for arriving at a differential diagnosis. As a rule, 

 an infection with this organism may be distinguished from anthrax by the fact 

 that in the former case the organism is not found in the blood. 



Gangrenous mammitis in sheep, W. Pfeiler (Ztschi: Infehtionskranl:. ii. 

 Ifpfl. HfiKstiere, ', (1908), Xo. 1-2, pp. 132-136).— A micrococcus was isolatetl 

 from the udder of a sheep affected with gangrenous inflammation. This organ- 

 ism was grown on a number of nutrient media and inoculation experiments 

 were tried to determine its pathogenic properties and the modes of infection. 

 The organism readily produced infection when injected directly into the udder 

 or through the nnlk canal. The mere presence of the bacillus upon the exterior 

 of the udder appears seldom lu produce an infection. There is, therefore, little
