fever would be a comparatively easy problem in that State. Infestation of 

 cattle with ticks persists by reason of driving herds in from Indian Territory 

 and from the lack of control of cattle on the public range. 



Progress made in exterminating the cattle fever tick in North Carolina, 

 T. BuTLKR {Ralei(/h: N. V. Dcpt. A(jr. [1907], pp. 5, figs. 3). — The author calls 

 attention to the progress which has been made since 1902 in exterminating cat- 

 tle ticks in North Carolina. 



During the past 5 years 20 counties of the State have been freed from ticks 

 and this is held as indicating what can be accomplished in all sections where 

 stock laws prevail. The price paid for cattle below the quarantine line is from 

 J to i ct. per pound less than for cattle of the same quality above the line and 

 this alone would mean a loss of $50,000 annually in the area which has been 

 freed from ticks. This amount is about three times the total cost of the work 

 of eradicating ticks in these counties during the entire 5 years. For the most 

 part the ticks have been eradicated by the use of the starvation method. 



Malignant catarrhal fever of cattle, E. Diem (Wchnschr. Ticrheilk. ii. 

 Viehsucht, 50 (1906), No. J,2, pp. 826, S27). — This disease has been almost un- 

 known in the region of Burghausen for the past nine years, but occurred to a 

 limited extent during the present season. The author treated 3 animals by 

 injecting 1.5 liters of physiological salt solution subcutaneously for 3 days in 

 succession. The treatment was without result. In this case it was believed 

 that infection came through the ground w^ater, and a suitable system of drain- 

 age was, therefore, recommended. 



An unusual case of chronic tympanites in cattle, IT. Holterbach {Berlin. 

 Tienirztl. WdiHschr., 1906. No. 37, pp. 679-6S1). — The usual symptoms of 

 tympanites are described with particular reference to a chronic case which 

 came under the author's observation. In this case the abdomen of the cow 

 became considerably distended with gas after each feed. Remedial treatment 

 was of no avail and the animal was slaughtered.' An examination of the intes- 

 tines showed that the duodenum was firmly attached to the liver, at which 

 point the lumen was very small. The intestine also made a sharp turn almost 

 at right angles at about the same level. 



Pathogenesis and treatment of railroad disease of cattle, J. Schmidt {Ber- 

 lin. Tierilrstl. Wchiisehr.. 1906, No. Ji3. pp. 77 5-779 ). — According to the obser- 

 vations reported in this article, railroad disease attacks chiefly pregnant cows 

 which have been maintained on pastures until the time of shipment. The 

 symptoms include fever, loss of appetite, and cerebral anemia. 



The author concludes that railroad disease of cattle should be described as an 

 anemia of the cerebral nervous system and disturbances of the vasomotor nerves 

 as a result of transportation in cars. No suitable preventive treatment has been 

 devised, but cases which have developed may be treated with much success by 

 inimping air into the udder in the same manner as recommended for ti'eatment 

 of milk fever. 



An investigation in the County of Wexford of a disease in young cattle, 

 J. H. NoKRis {Dept. Ayr. and Tech. In.str. Ireland Jour., 7 {1906), No. 1, pp. 17- 

 25, pis. 8). — Earlier investigations along this same line have already been noted 

 (E. S. R., 16, p. 1027). The author has contirmed his previous view that the 

 presence of Strongylus gracilis in the stomach of young cattle may cause a 

 serious wasting disease and death if no attention is given to the animals. 



Medical treatment of the disease appears to be of little value, but the trouble 

 may best be prevented by providing small clean pastures, in which the calves 

 may be maintained for the first year. 



Diseases of the stomach in cattle, A. Eber {Ztschr. Tiermed., 10 {1906), 

 2fos. 5, pp. 321-355; 6, pp. Jf01-Ji27). — The author presents in a succinct form a
