480 EXPERIMENT STATIC )I^ RECORD. 



The symptoms were very similar to tliose ot piiL'Uiuonia in the horse, includ- 

 ing fever and a catarrhal discharge. The mild oases ran a course of- 6 to 8 

 days, while in more serious cases the disease persisted for 4 to G weeks. A 

 favorable outcome took place in all cases, but 1 animal was slaughtered for 

 further observation. In this case there was a pronounced hepatization of the 

 lungs, and the bronchi were filled with a catarrhal secretion. 



The symptoms in general might cause a supi)ositi<)n of pleuro-pneumonia, but 

 the incubation period was not longer than 8 days, while in pleuro-pneumonia it 

 is ordinarily several weeks. 



The treatment of infectious vaginal catarrh of cattle by means of salves, 

 ScHWKiKERT (BcrUii. Ticrarztl. Wchiisclir., 1906, Xo. 35, pp. 639, 6JiO, fig. 1). — 

 The method of treating this disease, previously recommended by the author, con- 

 sists in the local ai)pIication of antiseptic salves by means of a syringe espe- 

 cially designed for this purpose. A number of veterinarians suggested the de- 

 sirability of having a syringe constructed in such a way as to be separable into 

 two parts for greater convenience of carrying. This has been done, and the 

 apparatus promises to be more convenient than a solid syringe. 



Epizootics of cowpox among dairy cows, Freger {Jour. Med. Vet. et 

 Zootech., 57 {1906), July, pp. 385-392, fir/. 1 ». — While cowpox is a benign disease 

 and does not lead to serious results with the cows, it may nevertheless cause 

 great annoyance in outbreaks of unusual extent. A number of such outbreaks 

 are described by the author. 



It was found that if the ordinary vaccine obtained from pustules on the udder 

 was used in vaccinating cows in the region of the perinemn the pustules rapidly 

 disappeared on the udder and the cows became noninfectious. The author be- 

 lieves, therefore, that the distribution of the disease may be rapidly cheeked 

 by adopting this method of treatment. 



Warble flies and their control by law, II. Ostertag {Ztschr. Fleisch u. 

 Milchhyg., 16 {1906), ^'o. 12, pp. Ji07-.',13) .—The life history of Hypodenna hovis 

 is described in considerable detail and notes ai'e given on the injury caused by 

 this pest to cattle hides. It is e.stimated that this insect causes in Germany a 

 loss of 6.000,000 to 8,000,000 marks. 



Tanners have suggested the desirability of a law compelling stock rai.sers to 

 remove and destroy all larviP of warble flies found ;n the skin of cattle. In a 

 few instances where this has I)een tried. ])articularly in Ireland, good results 

 have been observed. 



Trephining' the skull for Ccenurus cerebralis bovis, F. Braun {Wchnsclir. 

 Tierheilk. u. VicliziicJit. 5i)(19(JG), .Yo. .?'/. pp. 'i61-'i63). — Some unsatisfactory 

 experiences in operating to remove this j»arasitic worm are related by the 

 author. 



In one case the animal showed violent cerebral symptoms after an apparently 

 successful removal of the parasite and had to be killed. The author, therefore, 

 recommends against such operations since the i)arasite is usually located deep 

 in the tissue of the l)rain and since fre(iuently there may l)e several cysts in th*» 

 same brain. 



A disease of sheep in Ayrshire {Jour. Bd. Agr. [Loudon], 13 {1906), No. 5, 

 pp. 291-293 ). — I'arasitic gastritis appears in sheep during the months of May 

 and June, attacking most frequently ewes with young lambs. The first symp- 

 toms observed by the attendant are a lagging behind of affected sheep, a 

 disinclination to eat, and suspension of rumination. In many cases the animals 

 are found dead or die suddenly after the symptoms appear. Occasionally the 

 affected sheep rally from the first attack, but the disease reappears with greater 

 severity during the second season. The losses are estimated at from .1 to 10 

 per cent.
