this last quantity, one of the horses refused his food, and soon after 
was seized with violent diarrhoea, and this continued four days 
on him, at the expiration of which he died. The stomach proved 
in a high degree of inflammation ; the intestines, also, in an 
inflamed condition, but not to the same degree. The second 
horse continued the same doses of medicine four days longer, and 
then experienced a similar attack in the bowels, but less severe. 
This one also had his mouth made sore, and became salivated, for 
he cudded his hay and discharged freely saliva from his mouth. 
The mercury was now discontinued ; and, after the subsidence of 
the bowel-attack, some aloetic medicine was given, with a view of 
assisting the discharge of the mercury from the system. The 
horse recovered from the effects of the precipitate, and was 
subsequently destroyed on account of glanders. 
The third horse continued the medicine thirteen days longer 
than the second, taking regularly his four scruples daily. He 
was then attacked similarly to what the others had been ; not, 
however, so much in the bowels as in the mouth and salivary 
glands. He also recovered from the destructive influence of the 
mercury, but afterwards was put to death on account of being in- 
curably diseased.

By Mr. Youatt.

In the latter part of 1839, a disease, or rather a combination 
of diseases, began to appear among cattle in various parts of the 
United Kingdom. Even in its earliest stage it was composed of 
maladies whose seat was far distant from each other — whose 
symptoms were altogether unlike, and yet that were, sooner or 
later, inseparable and fatal companions. The mouth and the feet, 
the organs of assimilation and of respiration, so different in their 
character and in their management, were equally involved*. 
In May 1839, according to Mr. Beeson, of Amersham, the 
* I am truly grateful to very numerous friends who have kindly furnished 
me with sketches of the rise and progress, and most successful treatment, of 
this malady, and by whom I have been enabled to throw into some form and 
order that which would have otherwise presented one chaos of endless con- 
fusion. They will please to accept my cordial thank6.
