Salvarsan for the treatment of the pectoral form of equine influenza, 

 KiBSTEN {Berlin. Tierdrztl. Wchnschr., 27 {1911), No. 11, pp. 301-305).— A de- 

 scription is given of some very virulent cases of contagious pleuro-puenmonia 

 which occurred among the horses in a German cavah-y regiment and for which 

 dioxydiamidoarsenobenzol (Salvarsan or 606) was tried as r. therapeutic agent. 

 This was in some instances given in doses of 4 gm., but in the majority of cases 

 from 2 to 2.5 gm. for every 400 to 450 kg. of live weight were given. 



All animals treated with this agent made a comparatively rapid recovery. 

 The greatest disturbing factor was found to be the pain and restlessness caused 

 by the administration of the drug. Only 2 animals out of 7 were lost. 



The possibility of the disease being due to a protozoan is discussed. 



In regard to lymphangitis in the horse, G. Finzi {Rev. Gen. M6d. V6t., 18 

 {1911), No. 206, pp. 71-84, dgms. 2). — After describing the symptoms and post- 

 mortem findings with horses affected with a special form of lymphangitis, the 

 author gives the results of a study of the causative organism. 



The organism was found to be a nonsporulating cocco-strepto-bacillus from 

 2 to 5 ju. long which takes all basic anilin stains, but not Gram, and grows 

 aerobically and anaerobically in bouillon and on agar. It renders media acid, 

 does not coagulate milk, and can not be grown on potato or gelatin. The rabbit, 

 guinea pig, pigeon, and dog are very receptive to the organism, while bovines 

 are only slightly so. 



Operation for congenital cataract in a foal, O. Jobdal {Berlin. Tierdrstl. 

 Wchnschr., 27 {1911), No. 17, p. 307). — ^A one-year-old foal which was bom 

 blind was successfully operated upon for cataract in both eyes. The technique 

 used in the operation is described. 



Mortality among pigs, W. J. Young {Vet. Rcc, 2-', {1911), No. 1206, pp. 117, 

 118). — During the liist 9 months 100 dead pigs of all ages and sizes came to 

 autopsy at Sheffield, England, with the following findings : Tuberculosis in 22, 

 pneumonia 16, enteritis 7, swine erysipelas 6, swine fever 5, suffocation 5, 

 ascites 4, pulmonary congestion 3, cirrhosis of liver 3, verminous bronchitis 3, 

 internal hemorrhage 3, pericarditis 3, rickets 3, strangulated hernia 2, anthrax 

 2, pleurisy 2, gastritis 2, endocarditis 1, bacterial necrosis 1, metritis 1, epilepsy 

 1, peritonitis 1, hydrothorax 1, broken back 1, constipation 1, and liver disease 1. 



Tuberculosis when found was generally in the advanced stages. It is pointed 

 out that veterinary aid is seldom sought by farmers for hog ailments, as they 

 depend chiefly upon such remedies as comfrey, Spanish juice, antimony, black 

 sulphur, sirup of poppies, chamomile tea, castor oil, and proprietary pills. 



[Report of J departmental committee on swine fever {Jour. Compar. Path, 

 and Ther., 21^ {1911), No. 2, pp. 169-172). — This committee, which was appointed 

 by the Board of Agriculture and Fisheries of Great Britain in April, 1910, to 

 inquire into the cause of the continued prevalence of swine fever in Great 

 Britain and the possibility of speedily exterminating the disease, reported the 

 following conclusion: 



" Restriction on movement, including movement from markets, must continue 

 to form an essential part of any measures adopted to extirpate swine fever. 

 The ix)licy of 'slaughtering out' in the case of all outbreaks now in force iu 

 Scotland and Wales should be applied to the country generally as soon as 

 practicable. The present scale of compensation should be maintained. In the 

 general interest of the industry the size of infected areas should be kept as 

 small as possible, due regard being had to the object in view. In view of the 

 evidence as to the conditions prevailing in Ireland, we are of opinion that no 

 useful comparison can be made between the administrative methods of Great 

 Bfitaiu and Ireland. The same conclusion applies to continental countries."
