of serum and virulent blood. The advantages of the serum method are that it affords 

 immediate and full immunity and may cure the disease if applied during the period 

 of incubation. The serum may be stored and kept ready for use. It may also be 

 readily transported in bottles. Only one inoculation is required and there is prac- 

 tical certainty of securing good results if proper care is taken. 



Notwithstanding the many good points of various methods of treatment, it is 

 believed by the author that there is still room for improvement in the practical and 

 safe treatment of rinderpest. 



Inflammation of the udder in cows, M. G. de Bruin (Schweiz. Arch. Tierheilk., 

 47 (1905), No. 1, pp. 12-24). — The literature relating to this subject is briefly dis- 

 cussed. Notes are given on a number of different forms of inflammatory conditions 

 of the udder. These conditions may be due to streptococci, tubercle bacilli, and 

 other causes. 



In preventing the development of infectious mastitis it is recommended that the 

 straw or litter be furnished in a clean condition, that the cows' taiJs be prevented 

 from coming into contact with the filth, and that particular attention be given to the 

 feeding and management of cows for the purpose of preventing contamination with 

 bacteria. Attention should also be given to the health of the attendants and to the 

 temporary exclusion from the herd of all animals suffering from the retention of the 

 afterbirth, mastitis, wounds, and other diseases in the case of which bacteria might 

 gain entrance to the milk. 



Diseases of the stomach and bowels of cattle, A. J. Murray (U. S. Dept. Agr., 

 Bur. Anim. Indus. Circ. 68, pp. 10). — This is a revision by L. Pearson of an article in 

 the Special Report on the Diseases of Cattle (E. S. R., 16, p. 708). 



Intestinal coccidiosis of young- cattle, L. Degoix (Rev. Gen. Med. Vet, 3 (1904), 

 No. 28, pp. 177-186, figs. 8). — This disease is also known under the names hemor- 

 rhagic enteritis, bloody dysentery, etc. 



The first noticeable symptom is the sudden appearance of dysentery with a slight 

 fever, the appetite is lost, and rumination ceases. Emaciation takes place rapidly, 

 and is accompanied with considerable fever during the latter stages of the disease. 

 The duration of the disease is from 5 to 10 days, when recovery or death takes place. 

 In favorable cases recovery takes place rapidly. The author made a study of coccidia 

 in the alimentary tract of affected cattle. These organisms were never found in the 

 epithelial cells of the mucous layer of the intestines, but rather in the deeper lying 

 tissue. 



The pathological lesions of the disease were found throughout the whole extent of 

 the large intestines. The organism is described in detail. In controlling this dis- 

 ease the author recommends the disinfection of excrement from diseased cattle and 

 the administration of salol, creolin, or other substances as intestinal disinfectants. 



Abortion, or slinking the calf, J. Law ( U. S. Dept. Agr., Bur. Anim. Indus. 

 Circ. 67, pp. 11). — This is reprinted from the Special Report on the Diseases of Cattle 

 (E. S. R., 16, p. 708). 



Osteomalacia, or creeps, in cattle, J. R. Mohler ( U. S. Dept. Agr., Bur. Anim. 

 Indus. Circ. 66, pp. 2). — This is reprinted from the Special Report on the Diseases of 

 Cattle (E. S. R., 16, p. 708).

Cattle poisoned by fresh paint, E. H. Jenkins (Connecticut State Sta. Rpt. 1904, 

 pt. 5, p. 448). — Mention is made of the poisoning of 2 cows by paint which had been 

 consumed with the grass upon which the paint had been spilled, or licked from 

 freshly painted boards.
