form of the disease prevailing in the Transvaal. It is believed, however, that 

 healthy animals may be successfully immunized against the virulent form of the 

 disease, by using blood of animals which have recovered from this disease, under the 

 usual i)recautions which are recognized as necessary to the success of such inocula- 

 tion exi)eriments. 



Rinderpest in Cape Colony (Agr. Jour. Cape Good Hope, 23 {1903), No. 1, pp. 

 70-SJ, plx. 5). — This article deals chiefly with an accomit of the serum station at 

 Aliwal North. Two extensive outbreaks of rinderpest have occurred in Cape Colony 

 and the disease has been stamped out in both instances with considerable rapidity by 

 inoculation of healthy animals with the serum or bile of recovered or diseased ani- 

 mals. Detailed notes are given on the methods employed at the Aliwal North station 

 in preparing serum and bile, and of the treatment and management of infected herds. 



A note on tick infestation, C. P. Lounsbury ( Transvaal Agr. .Tour., 1 {1903), No. 4, 

 pp. 11, 12) . — Experiments are in progress to determine the species of ticks which are 

 concerned in carrying the virulent form of Texas fever which prevails in South Africa. 

 According to determinations made by G. Neumann, Rhlpicephalus sMpleyi and R. 

 siimis are instrumental in carrying this disease. The author believes, however, that 

 these determinations are only preliminary and may be shown to be incorrect after a 

 larger amomit of material is examined. 



A bacterial form of bovine piroplasmosis, A. Laverax ( Compt. Rend. Acad. 

 /Sfci. Paris, 136 {1903), No. 11, pp. 648-653, figs. 18). — The bacterial form of Piroplasma 

 higeminum was sent from Rhodesia to the author by Theiler. This organism is 

 described in detail and notes are given on its prevalence in the cases of Texas fever 

 which have recently been investigated in Rhodesia. The form of Texas fever which 

 prevails there is unusually virulent. The organism is considered as a variety of the 

 ordinary specific form. The possibility is suggested of this being a new species of 

 piroplasma and the suggestion is based on the fact of its unusual virulence and 

 peculiar symptoms manifested in affected cattle. 



Spirillosis in Bovidse, A. Laveran {Compt. Rend. Acad. Sci. Paris, 136 {1903), 

 No. 16, pp. 939-941, fig. 1). — A species of Spirillum was found in the blood of cattle 

 in the Transvaal. The author describes this organism in detail. The cattle in which 

 the organism was found were also affected with Texas fever and the pathogenic 

 action of the Spirillum therefore remains doubtful. 



liamziekte and impaction of the third stomach, D. Hutcheon {Agr. Jour. 

 Cape Good Hope, 23 {1903), No. l,pp. 25-28). — Lamziekte is described as a lameness 

 or nervous affection in cattle which may be due to congestion of the liver. The 

 symptoms of the disease are described in detail. Impaction of the third stomach is 

 described with especial reference to the cause and treatment of this trouble. 



Indigestion and diarrhea in calves, D. Hutcheon {Agr. Jour. Cape Good Hope, 

 22 {1903), No. 6, pp. 669-681). — The author describes in detail the symptams, 

 etiology, and treatment of diarrhea due to sudden changes of diet or to intestinal 

 parasites, as well as infectious diarrhea or so-called white scour in calves. A brief 

 discussion is also presented on the subject of liver disease in calves. 



Contagious abortion in cows, J. Law {California Sta. Circ. 5, pp. 13). — A popu- 

 lar account of the forms of abortion, together with a discussion of the etiology, 

 symptoms, prevention, and treatment of this disease. 



Sterility in cattle and sheep {Agr. Jour. Cape Good Hope, 22 {1903), No. 6, jyp. 

 658-661).— A. brief discussion is given on the possible action of salt in causing ster- 

 ility. It is not believed that any such effect can be produced by salt under ordinary 

 conditions. Brief notes are also given on the veterinary use of Stockholm tar. 



Plants injurious to stock, C. W. Peterson {Rpt. Dept. Agr. Northwest Territories, 

 1902, pp. 33-44).— ^otes are given on Pulsatilla hirsutissima, spear grass, common 

 horsetail, oat smut, ergot, larkspur, corn cockle, Thermopsis, lupines, loco weed, 

 chokecherry, water hemlock, sneeze weed, death camas, Solanum iriflorum, and
