258 DISEASES OF CATTLE. 



There is a distressing and painful cough, and not unfrequently a 

 8ore throat also, in which case the beast almost invariably holds 

 down his head. The treatment does not at all differ from that 

 directed under the same disease in horses (13.) Bleeding only tho 

 first two days, carefully sheltering, but in an open airy place, lit- 

 tering well up. 



178. The malignant epidemic influenza is popularly called muT' 

 ain or psst ; and has at various times made terrible havoc among 

 rattle. xA.ncient history affords ample proof of its long existence, 

 and by the accounts handed down, it does not seem to have varied 

 its types materially. In 1757 it visited Britain, producing extreme 

 fatality among the kine. From 1710 to 1714 it continued to rage 

 on the continent with unabated fur}'', (Lancisiss Disputatio His- 

 lorica cle Bovilla Peste.) The years 1730 and 1731, and from 1744 

 to 1746, witnessed its attack, and produced many written descrip. 

 tions of it, among which stands pre-eminent that of Sauvages, tho 

 celebrated professor of medicine, at Montpelier. The British visi- 

 tation of the malady in 1757, elicited an excellent work from the pen 

 of Dr. Layard, a physician of Iiondon, which was afterwards trans- 

 lated into several languages.

179. Syrnptoms of the murrain. Dr. Layard describes it as cora 

 mencing by a difhculty of swallowing, and itching of the earr 

 shaking of the head, with excessive weakness and staggering gait 

 which occasions a continual desire to lie down. A sanious foetid 

 discharge invariably appears from the nostrils, and eyes also.— 

 The cough was frequent and urgent. Fever, exacerbiating, par 

 ticularly at night, when it usually produced quickened pulse.— 

 There was constant scouring of green foetid dung after the first 

 two days, which tainted every thing around, even the breath, per 

 spiration, and urine were highly foetid. Little tumours or boils v/ere 

 very commonly felt under the skin, and if about the seventh oi 

 nmth day these eruptions become larger, and boils or buboes appear 

 v\ ith lessened discharge of fieces, they proved critical and the animaJ 

 often recovered ; but if on the contrary, the scouring continued, and 

 iJie breath became cold, and the mouth dark in colour, he intorma 

 ue mortality followed. Sauvages describes the murrain as showing 

 Itself by trembling, cold shivers, nose excorated with an acid dis- 

 charge from it ; purging after the first two days, but previous to 

 which there was often costiveness. Great tenderness about the 

 spme and withers was also a characteristic, with emphysema, or a 

 bJowjng up of the skin. by air discharged underneath it
