106 Dr. A. P. W. Philip on the 
ing the formation of the secreted fluids, and other processes of 
assimilation, when duly applied to the proper parts, while they 
retain the vital principle. Itremains to inquire whether it can 
raise the temperature of living arterial blood; that is, living 
blood which has not already undergone the effects of the influ- 
ence of the nervous system. 
That it is capable of this function appears from the 77th and 
79th experiments related in the above-mentioned Inquiry. The 
rise of temperature was immediate and considerable in one expe- 
riment 3°, in another 4°, From the 76th and 78th experiments it 
appears that galvanism has no power to raise the temperature of 
arterial blood after it has been exposed even for the short period 
of aminute and ahalf. It is necessary that the galyanism should 
act on it as it flows from the vessels, possessing all its vital pro- 
perties. From the 80th, 81st, and 82d experiments, it appears 
that galvanism has no power to raise the temperature of venous 
blood; that is, blood which has already undergone the effects 
of the nervous influence, although applied to it immediately on 
its leaving the vessels. 
In the seventh volume of the Medico-Chirurgical Transactions, 
Mr. Henry Earle notices cases of palsy, in which the temperature 
of the paralytic limb, although the pulse was good, was lower 
than that of the rest of the body. In one of them the electric in- 
fluence was passed through the limb, and was found to raise its 
temperature *. 
But raising the temperature of the blood seems not to be the only 
effect of galvanism on this fluid, which corresponds with the ef- 
fects of the influence of the nervous system on it. Two other 
remarkable effects of this influence on the blood appear to be 
darkening its colour and exciting its coagulating power. It is only
