EPIDEMIC DISEASE IN CATTLE. 
lime, and it is now entirely healed. The foot is now little larger 
than the other, and the animal, though still lame, will soon be as 
sound as ever. 
The patient was suspended in a sling, holding the affected foot 
up from the ground for six weeks, and every attention was paid 
to her by the owner, for which he was repaid in a singular 
manner. The cow, when at the worst, gave eight or nine quarts 
per diem of milk, gradually increasing in quantity to eighteen or 
nineteen as she became convalescent. From the length of time 
that the foot was held up, the muscles of the posterior hyo-femo- 
ral region, and some of the others (I suppose from want of 
action) were very much atrophied, but they have now almost re- 
gained their former bulk. Were I inclined, I might, in review- 
ing the case, make many other statements in connexion with 
it; but, as l think they would lack interest, [ must refrain. 
One thing, however, I must say, — that from it I hope to derive 
many a valuable hint for the future; for this instance of recovery 
will shew me the necessity of perseverance, and of exercising hope 
and patience in the employment of those means which we possess 
to combat disease and its effect on the animal frame. No doubt 
nature has done much ; at least she gifted the animal with a 
sound constitution, and we will only claim the honour of assist- 
ing her in her endeavours to restore from disease to health. 
I have just now received a long three-sheet folio letter from 
Mr. . He mentions a case of ophthalmia (specific) 
cured by the cautery being applied to the frontal bones, after all 
other means had failed. This is a revival of the ‘‘old farriers’ 
remedy.” The best case is one of poisoning, from a mare eating 
meal and arsenic, which was placed under the manger to kill 
mice, &c. His treatment was, first, a large dose of sweet oil, and 
the albuminous part of a dozen eggs ; next, a quantity of melted 
suet, prepared chalk Jiij, milk 1 quart, lime-water and more oil, 
which proved successful. 
We have lately had many cases of laryngitis, sometimes with 
bronchitis, and occasionally pleuritic symptoms. We have lost 
four cases, three of which had hydrothorax, with a curdy cheese- 
like matter contained in cellules or the substance of the lung, 
and coagulable masses floating in the contained fluid of the chest. 
The pleura appeared to be in a gangrenous state, and also the 
membrane lining the trachea. I think the symptoms of hydro- 
thorax are not easily detected, as they vary so in different cases. 
The continued standing in one position, with extended neck and 
rattle in the trachea, with oppressed pulse and very foetid breath, 
and discharge from nostrils, were the principal symptoms. 
I see Mr. Percivall attributes the cure of three cases in the
