ON THE EPIZOOTIC DISEASES OF CATTLE.

epidemic which has lately prevailed consisted chiefly of a disease 
of the heart. In corroboration of this, I can assert that, in all the 
cases which I have had an opportunity of examining after death, 
this organ was more or less diseased. 
ON THE EPIZOOTIC DISEASES OE CATTLE IN 
1839-40. 
[Continued from page 451.] 
[When describing the epizootic disease of cattle that occurred in 
1839-40, I alluded to a letter from Mr. Hutchinson, V.S., 
of East Retford, which was reserved for some future opportu- 
nity. It is peculiarly interesting and valuable, on account of 
the detailed history which is given of so many of the cases. 
Our readers will not object to our inserting it at very consi- 
derable length. — Y.] 
July 7th, 1840. — Mr. Gamston had seven milk cows. The 
first of them was affected on this day, and the others were ill on 
the third day. I found them with a large quantity of saliva hang- 
ing about the lips, and they constantly champing with a peculiar 
sucking sound — the eyes dull and sunken — disinclination for food 
— yielding about half of their usual quantity of milk — frequently 
lying down — the flank presenting a hollow, empty appearance — 
and all of them being excessively lame. Upon examination I 
found the tongue one complete mass of blisters — the skin, by 
the least force, was drawn completely off — a considerable portion 
of the heels of the horny sole had separated. 
I commenced my treatment by paring the detached portions 
of horny sole away, and dressing the feet with a solution of sul- 
phate of copper. To some of them I applied a poultice for 
twenty-four hours. I gave to each an aperient draught, con- 
sisting of sulphate of magnesia, nitrate of potash, resin, and 
aloes, with ginger or some aromatic powder, in warm water : I 
also ordered them to be drenched freely with linseed cake gruel, 
to be fed upon clover, and to be kept in. 
On the following day they all, excepting two, appeared much 
better ; these I bled to six pints, and repeated the aperient 
draught. To the others I at once gave a tonic draught, com- 
posed of sulphate of copper, ginger, and some other aromatic 
powders,, with nitrate of potash and yellow resin, dissolved in
