able dipping plant for a few farmers may be liuild for $150, while a swimming tank 

 costs $350 or more. A detailed description with illustrations is given of a large and 

 a small dipping vat for this purpose.

 figs. 15). — A popular edition of the preceding bulletin. 



Foot-and-mouth, disease, with an account of the outbreak in Suflfolk dur- 

 ing 1901, E.J. Cheney (^grr. Students' Gaz., n. ser., 10 {1901), No. 5, pp. 135-UO).— 

 A brief general account of this disease is presented, with special reference to an out- 

 break in Suffolk. The first case in this outbreak was reported on January 26, in a herd 

 of cows, and 40 of the animals had to be slaughtered. Further outbreaks occurred at 

 intervals for the next .3 months. All cases of this disease were within a radius of 5 

 miles. The origin of the infection in the first case was not determined. 



Treatment for foot rot, J. Cotton {Agr. Gaz. Neiu South Wales, 12 {1901), No. 2, 

 p. 1394)- — As a remedy for foot rot in sheep the author recommends a mixture con- 

 taining \ lb. copper suljihate, ^ lb. common salt, and 1 qt. of water. The mixture is 

 to be boiled for about 10 minutes in order to dissolve the copper sulphate. 



Bots in sheep, J. D. Stewart {Agr. Gaz. Netv South Wales, 12 {1901), No. 12, pp. 

 1542, 1543, pi. 1) . — The sheep bot fly is of comparatively rare occurrence in New South 

 Wales. The symptoms of the disease are given from cases observed by the author 

 and the insect which causes the trouble is described in all its stages. The usual 

 remedies for the disease are recommended. 



Immunization against swine plague and hog cholera by means of immune 

 proteidin, H. Greither {Inaug. Diss. Vidr. Bern, 1901, pp. 16). — The author 

 attempted to apply in the treatment of swine plague and hog cholera the method 

 proposed by Emmerich and Low, according to which immune enzyms are applied in 

 checking the development of contagious diseases. It was found that a bacteriolytic 

 enzym was formed in fluid cultures of swine-plague bacteria and in experiments with 

 this disease inoculation with this enzym had the effect of checking the disease. Sim- 

 ilar experiments with hog cholera were not so encouraging. It was found during 

 these experiments that hog-cholera bacteria in bouillon cultures containing nitrates 

 formed large quantities of nitric acid within a short period. It is suggested that this 

 effect might also l)e produced in the intestines of hogs suffering from hog cholera, and 

 it is therefore recommended that no food containing nitrates be given during the 

 prevalence of this disease. 



Pulmonary antisepsis in infectious pneumonia of horses, Pruneau {Rec. Med. 

 Vet., Paris, 8. ser., 8 {1901), No. 5, pp. 145-155) . — The author discusses the action and 

 effectiveness of various antiseptics which are suitable to be applied in the way of 

 intratracheal injections. The following formula was used in experimental treatment 

 of the disease: Eucalyptol 5 gm., guaiacol 5, menthol 5, essence of thyme 10, 

 essence of wintergreen 10, essence of cinnamon 10, essence of turpentine 30, iodoform 

 10, pure sterilized olive oil 150. The chemical action of this mixture brings about a 

 disinfection of the respiratory passages, drying of the mucous surfaces, cessation of 

 cough, and a more rajsid absorption of medicinal substances by the pulmonary mucous 

 surfaces. The mixture was injected into the trachea by the ordinary method in doses 

 of 20 cc. Experiments on 9 horses indicated that this mixture checks the develop- 

 ment of the pathogenic micro-organisms to such an extent that the chances of a rapid 

 and complete recovery are much increased. 



Emergency report on surra, D. E. Salmon, C. W. Stiles, and A. Hassall ( V. S. 

 Dept. Agr., Bureau of Animal Industry Bid. 42, pp. 162, pis. 33, figs. 79). — This report 

 Avas prepared by the authors in response to a request from the War Department for 

 information concerning surra. The disease recently began to attract attention in the 

 Philippines, where it affects horses, mules, and caribao. The present report is com. 

 piled from the literature of the subject, especially from the works of A. Lingard, G. ' 

 Evans, et al. The report includes a discussion of all the principal problems connected
