DR DAVY ON THE COAGULATION OF THE BLOOD. ST 
ceived” This I have stated in a note to Dr Bratrr’s “ Treatise on Yellow 
Fever” (the epidemic which preceded the one last mentioned), of which I was the 
editor. 
I shall now conclude, briefly remarking, that as the results I have described 
are opposed to the inference of the coagulation of the blood being owing to the 
escape of any volatile matter, and, « fortior?, of the volatile alkali, the existence 
of which in the blood even remains to be proved, they leave the phenomenon, as 
hitherto, a problem for solution, and open to question whether it be the result 
of loss of vitality, or a chemical result, depending on a new arrangement of ele- 
ments of the coagulating part, the fibrin, without, as regards their number, any 
change of their sum.
