one at 22°. Whether this anomaly in the circu- 
lation of the two.arms had arisen from some 
organical difference in the structure of their arte- 
ries, or from the treatment which he had received, 
it is difficult to decide; perhaps both these causes 
might have co-operated, for he had taken nux 
vomica in great quantities; and in all the cases of 
paralysis where this medicine had been adminis- 
tered, I have uniformly found the pulse of the 
paralytic arm comparatively strong. Two small 
eschars, made with the nitrate of silver, were 
formed on the head; at the end of two weeks 
there was no perceptible effect from them, except 
that the right iris had expanded nearly to its 
natural dimension. The temperature of the room, 
and the superior extremities, being nearly in the 
same relation as above stated, an eschar, the size 
of a sixpence, was made on the back of the neck, 
but causing no alteration of temperature, another, 
half the size, was formed on the head. The day 
following, there was little alteration of the pulsa- 
tion; but the temperature of the paralytic hand 
was found to have risen from 19° to 22° Reau- 
mur; the heat of the whole hand had also risen 
something more than jth of adegree. The flexor 
muscles of the right hand, which had formerly 
been in a state of rigid contraction, were now 
expanded, and easily moved by external force; 
but voluntary motion was not in the least restored,
