332 PRIZE ESSAY : — PLEUROPNEUMONIA AMONG CATTLE. 
That the Society are, from their experience of the actual working 
of the law, fully sensible of its defects; that they are, as they ever 
have been, anxious to remedy those defects ; and are prepared to 
lay before the Secretary of State such suggestions for the amend- 
ment of the Act as would, in their opinion, go far to remove the 
objections which exist to its provisions, and would, at least, remove 
many of the impediments in the way of a satisfactory settlement 
of the complicated question of Medical Reform, not only as regards

On behalf of the Society,

to be able to add, that in this, as in former instances of the kind, 
fortune has favoured the veterinary profession.]

parts — first appeared in this country about the year 1841 — previ- 
ous to which period it had existed and committed great ravages 
among the cattle in Ireland, and on the continent — and in England 
a very great proportion of the whole number of cattle which have 
been affected have died. 
It is a rare thing for any epizootic disease to rage alone — that 
is, without being preceded or followed by some other. It will be 
remembered that the vesicular epizootic, which first appeared here 
about the year 1839, was the forerunner, and is to this day the 
companion, of the present pleuro-pulmonic disease ; but the ulti-
