striking lameness and a general paralysis similar to that which appears in 

 milk fever. As a rule, the animals begin to recover on the second or third 

 day and the mortality is not greater than 5 per cent. There is usually a 

 noticeable swelling around the eyes and an Increased secretion of tears. The 

 blood is somewhat altered in character, clots readily, and shows a tendency 

 to collect in the pericardium. The lining of the abomasum is greatly inflamed. 

 The cause of this disease has not been determined. When the blood of affected 

 animals is inoculated into sheep a typical fever develops within 6 to 10 days, 

 but the fever is not accompanied by stiffness. 



Parturient eclampsia in the cow, H. Taylor (Vet. Rec, 20 (1907), No. 999, 

 pp. IJfl, i.'/2).— Clinical notes are given on 3 cases of this disease observed by 

 the author. It is considered to be very rare. The administration of aperients 

 followed by bromid of potash brought about a cure in 2 of the 3 cases. 



Enzootic retention of the afterbirth, H. Holterbach {Dent. Tierdrztl. 

 Wchnschr., 15 {.1901), No. 26, pp. 365-368). — During the author's veterinary 

 practice the number of cases of retention of the afterbirth in cattle has varied 

 greatly in different years. Mention is made of four years in particular during 

 which the disease appeared to an unusual extent. It was observed that in 

 seasons when this trouble appeared most extensively in cattle, rachitis was also 

 unusually prevalent among pigs and other young animals. 



The author has come to the conclusion that the cause vOf enzootic retention 

 of the afterbirth is to be found in an insufficient amount of lime in the food. 

 In years of unfavorable weather it is well known that forage plants may 

 not contain the same amount of mineral elements that they do when grown 

 under more favorable conditions. P]xperiments in adding phosphate of lime 

 to the ration indicate that this remedy will give favorable results, The author, 

 therefore, recommends that phosphate of lime be added daily to the ration of 

 breeding animals, especially during seasons unfavorable for the best growth of 

 plants. 



The organisms of calf dysentery and coli bacillosis, G. Neumann {Centbl. 

 Bakt. [etc.], 1. Abt., Orig., ^1, {1901), No. 3, pp. 2i 3-223). —Some races of calf 

 dysentery bacilli are very virulent for guinea pigs, either by subcutaneous or 

 intraperitoneal inoculation. Agglutination experiments failed to support the 

 theory of the specific action of the coli bacillus in causing calf dysentery. 



White-spot kidney in calves, V. Fally {Ann. MM. YH., 56 {1907), No. 8-9, 

 pp. J/63-J/68, pi. 1 ) . — From a histological study of the phenomenon of white-spot 

 kidney in calves the author comes to the conclusion that in the great majority 

 of cases this condition is an interstitial nephritis with circumscribed foci. In 

 some cases the white spots may be the remains of embryonic tissue. 



Coenurus serialis found in two goats in India, S. H. Gaiger {Jour. Trop. 

 Vet. ScL, 2 {1907), No. 3, pp. 316-321, pis. 3, figs. 4). — The normal host of Ccenu- 

 rus serialis is the rabbit, and some interest, therefore, attaches to the fact that 

 the author has found it in 2 instances in goats. The interrelations of the host 

 and parasite art» discussed. 



The etiology of swine plague and hog cholera, R. Ostertag and A. Stadie 

 {Ztschr. Infcktionskrank. u. Hyg. Haustierc, 2 {1907), No. 6, pp. .',25-^58).— The 

 numerous experiments reported by the authors in filtering the virus of hog 

 cholera and swine plague have led to results which are at variance with those 

 recently announced by Hutyra. In the experiments reported by the authors it 

 was found possible to produce hog cholera with the filtered virus from animals 

 simultaneously affected with hog cholera and swine plague. Intrapleural in- 

 oculation was in all cases more effective than subcutaneous. 



In a parallel series of experiments it was determined that the virus of pure 

 swine plague is not filterable, and also that the virus of the form of swine
