of the arsenical dipping solution " may be minimized or entirely prevented by 

 tbe addition of commercial copperas, after the solution has been rendered ex- 

 cessively alkaline through the addition of air-slaked lime. The clear solution 

 left on top, after the addition of the copperas solution, should contain no 

 arsenic, and may, with safety, be pumped or siphoned to any convenient place; 

 and the sediment remaining buried in a small hole dug for the purpose. . . . 

 This method is simple, effective, and inexpensive, and if adopted, may be the 

 means of preventing casualties from the careless disposal of the poisonous 

 arsenical solution." 



Notes on a trypanosome found in a sheep tick, and its probable connection 

 with the disease known as louping- ill, C. E. Bishop {Vet. Jour., 67 {1911), 

 No. Jf38, pp. 709-715, fig. 1). — The author reports finding a trypanosome in 

 ticks taken from sheep. Up to the present time, however, all examinations of 

 blood or organs of diseased sheep have failed to show the presence of the same 

 form. 



An infectious foot disease of sheep, A. Theileb {Yet. Jour., 67 {1911), No. 

 Ji37, pp. 659-663; Aqv. Jour. Union So. Africa, 2 {1911), No. 1, pp. 29-32, pis. 

 2). — A foot from each of 2 sheep were examined for the cause of lameness in a 

 flock at Rietvlei near Johannesburg, South Africa. 



The disease first manifested itself above the hoof, and later involved the hoof 

 itself, where it caused deformity in the growth and length of the horn of the 

 foot, and an ulceration or a thickening of the matrix of the coronary band. 

 The necrosis bacillus was absent in these and other cases examined, but a coccus 

 was noted which was gram positive, grew on agar slants as transparent 

 droplets the size of a pin head which when reinoculated on agar formed trans- 

 parent films. The disease could be reproduced when a pure culture was 

 inoculated. 



The treatment used was a thorough cleaning of the wound, preferably 

 by means of warm water and a disinfectant, such as 3 per cent carbolic acid, 

 and a dressing of the wound by means of a disinfecting and astringent oint- 

 ment. A cheap and effective ointment is suggested, consisting of powdered cop- 

 per sulphate, 10 parts, fat, 70 parts, and Stockholm tar, 5 parts. " When the 

 ulcer has penetrated into the matrix of the hoof and the horn becomes de- 

 tached, it is advisable to cut it away and to clean and dress the wound under- 

 neath . . . When a luxuriant growth or unhealthy gi-anulation develops, cauter- 

 izing with nitrate of silver can be recommended." 



Experiments with Krafft's vaccine against hog cholera, J. Koves {Berlin. 

 Tierdrztl. Wchnschr.. 26 {1910), No. //.9, pp. 973, 97'//).— In these tests, which 

 were made for the purpose of determining the protective and curative properties 

 of this vaccine, 1.32 healthy pigs from 2 weeks to 4 months old and having an 

 average weight of 17 kg. were kept in infected quarters. Of these (a) 8 were 

 kept as controls, (b) 10 were injected with 4 cc. of Krafft's vaccine on July 2 

 ;md 14 (protective vaccination), (c) 10 received 10 cc. of the vaccine after 

 natural infection had set in (curative treatment (, (d) 8 received 2 cc. of hog- 

 cholera virus subcutaneously, and (e) 96 received 2 cc. of hog-cholera virus in 

 various parts of the body and 10 cc. of hog cholera immune serum under the 

 skin. 



The receptive mortality was for (a) 75, (b) SO, (c) 60, (d) 87.5, and (e) 

 9.41 per cent. 



Do complications of swine plague and hog cholera occur? Koeppen {Berlin. 

 Tierarztl. Wchnschr., 26 {1910), No. 49, pp. 97Jf, 975).— The author believes that 

 the pectoral form of swine plague is a metastatic Infection of the lungs which 

 originates from the intestines of animals affected with hog cholera. According 

 to this, the diseases must be considered identical.
