14 ; ANALYTIC SECT. II. 
When the sloughs fell off, the iris alone remained 
permanently affected by the eschars; the muscles 
of the paralytic arm fell back to their former | 
contracted state, and its temperature to its usual 
low standard, when exposed to a cold atmo- 
sphere. ‘The eschars were consequently discon- 
tinued. When this patient was in bed, and 
well-covered with blankets, the heat of the para- 
lytic muscles was natural. This circumstance, so 
far as my observation extends, is common to all 
cases of hemiplegia. 
xu. In patients afflicted with hemiplegia, the 
circulation is in general languid on the whole of 
the paralytic side; but even in all such cases it is 
easy to raise its temperature to an equality with 
that of the whole side, by a lunar caustic eschar, if 
the apoplectic symptoms have for some time dis- 
appeared. A case of this description I shall relate 
under the head of Muscular Irritability. As an 
eschar of lunar caustic, over the nerve of a para- 
lytic limb, causes an augmentation of heat through 
all its ramifications, it necessarily follows, that the 
nervous system must contribute greatly to the 
generation of animal heat; but as the nervous 
system may be made to cease its calorific action, by 
the abstraction of blood, animal heat must there- 
fore be a product arising from the combined action 
of the blood and nervous system, and does not 
depend solely upon either the one or the other.
