probably have remained wholly fluid ; whereas in this case, the 
animal being only in progress towards that state—being only 
urged to a point from which he could recover—the coagulating 
powers of the blood were merely diminished. 
I shall conclude this subject with a statement of the results of 
bleeding twelve horses in perfect health, under circumstances as 
nearly as possible similar and natural. From each horse the 
quantity drawn was one pint. The time it took in flowing in no 
case exceeded a minute. A film of coagulum was generally per¬ 
ceptible on the surface at the expiration of ten minutes. Each 
parcel was firmly coagulated in twenty-five minutes. All the 
coagula shewed buff about half an inch in depth; seven of them 
were very firm, of which five exhibited the surrounding edge 
elevated and turned in, the other two being still more decidedly 
cupped. In two out of the five not so firmly congealed, the 
coagula were soft and flabby. The serum amounted in every 
parcel to about one-half of the whole quantity.

In the present lecture it is my intention to give a sketch or 
outline of the mode in which chemical philosophy may be applied 
to illustrate the general constitution and operations of the animal 
economy. To these views I was gradually led many years ago;
