blood parasite which causes the disease is described and notes are given on the 

 symptoms of redwater or Texas fever. A Bummary accounl i^ also given <>i some of 

 the experimental work done in this country on this disease. 



Cattle tick investigation, A. Mayer (Proc. /.". i x c. and Stockbreed. Assoc, 

 /!">.-,, pp. 103-110). — Attention is called to the great economic importance of the 

 cattle tick. 



This pest not only stunts the development of cattle so that they tail to reach their 

 normal size, bul also reduces the market price <>t rattle raised below the quarantine 

 line. On account of the fact that there are large tick-free areas below the quaran- 

 tine line cattle raised en such areas must he inoculate. I or gradually Infested with 

 ticks in early life, others ise they are as susceptible to Texas fever as northern cattle. 

 Considerable reliance i< placed in the use of good dip- for destroying ticks, hut 

 attention is called to the desirability of systematic- week in exterminating the tick. 



The etiology of pneumonia, Rips Berlin. Tierarztl. Wchnschr., 1906, No. 8, i>i>. 

 J.'!', ISO). — Excellent opportunity was had for the study of this disease in hoi 

 It appeared as an infectious disease without special localization in the lungs, and at 

 the outbreak of the symptoms considerable catarrh was noted in the upper part of 



the respiratory passages, hut this was much less pronounced than the catarrhal con- 

 dition of the duodenum. The temperature rose on the second day to 40.5 *'., 

 but fell to normal again within 8 days. 



The persistence of tetanus spores in the animal organism in a latent form, 

 (.. Tarozzi (Centbl. Bakt. [efc.], 1. Abt., Orig., ',<> i 1906 . Nos. 3, pp. 306-311; ./, pp. 

 451-458). — Guinea pigs and rabbits were used in the experiments reported in this 

 paper, being inoculated with virulent tetanus cultures which had been kept under 

 aerobic conditions. Only 11 animals were used in the experiments for the purpose 

 of determining whether and how long tetanus spores remain in a latent condition in 

 inoculated animals. 



It was found possible to demonstrate the spores in all cases in the liver, usually in 

 the spleen, hut, as a ride, not in the kidneys. The author considers that these 

 experiments demonstrate that the tetanus spores pa— into the general blood circula- 

 tion from the point of inoculation and become located in various vital organs where 

 they may persist in a virulent Condition for a long period. When removed from 

 such organs they are capable of producing very toxic culture-. 



Infectious diarrhea of calves and liver disease of chickens, X. S. Mayo 

 (Estac. Cent. Agron. Cuba Circ. ;.\ />/>. f). — Brief notes are given on the distribution 

 of infectious diarrhea in calves together with notes on the rate of mortality and anti- 

 septic treatment to he adopted in preventing the disease. For this purpose the author 

 recommends creolin. A disease of fowls known as little liver is described. The dis- 

 ease is, however, not characterized by lesions in the liver, hut by symptoms which 

 closely resemble those of roup. In treating the disease the author recommends the 

 use of potassium permanganate in water at the rate of 1 part to (it). 



Diseases of the stomachs in ruminants, J. L. Webu i \<it<tl Agr. .four, and Mm. 

 Bee , 9 (1906), No. /, pp. 1-7 ). — < attle are susceptible to various digestive troubles on 

 account of their tendency to eat various indigestible or otherwise harmful suh-tanees. 

 In this way hair halls are formed in the stomach and actual lesion- may he produced 

 as the result of eating bones or other materials with sharp points. An account is 

 given of impaction of the omasum, gastritis, and parasitic irritation of the fourth 

 stomach. In removing these parasitic worms the author recommends the use of a 

 mixture of 2 <>/.. areca nut ami 30 grains of arsenic made into L0 doses and given daily 

 for a period of 6 days in hran. 



Enzyms in cornstalks and their relation to cornstalk disease, T. M. Price

 annual report of the Bureau for 1904 (E. 8. K., 17, p. 702).
