ON FEVER IN THE HORSE. 
By Mr. Green, V. S. 
[Head at the Veterinary Medical Society on March the 8th, 1830.] 
Gentlemen, 
In bringing the present paper on fever before the Society for 
their consideration, I have taken upon myself a more difficult 
task, perhaps, than I am aware of; and I feel no small degree 
of hesitation in producing a paper of this nature before practical 
men, well knowing how incompetent I am to the task ; and 
among all and the many veterinary works I have consulted, having 
derived little or no assistance; indeed, the only one that treats 
of a fever as a disease (sui generis) is Mr. Percivall. I have, 
however, done so, not with a view of offering any thing new' 
upon the subject, but to endeavour to elicit that knowledge from
