Firft, that fo long as the animal retains the powers, 
though deprived of the adion, of life, the caufe of that 
privation may frequently be removed; but, when the 
powers of life are destroyed, the action ceales to be re- 
coverable. Secondly, it is neceffary to mention that I 
confider part of the living principle as inherent in the 
blood <*). The laft propofition I have to eftabliih is, that 
the ftomach fympathizes with every part of an animal, 
and that every part fympathizes with the ftomach ; there- 
fore, whatever ads upon the ftomach as a cordial, or 
roufes its natural and healthy addons, and whatever af-

upon every part of the body. This lympathy is ftrongeft 
with the vital parts. Belides this univerfal lympathy 
between the ftomach and all parts of the body, there are

experiments. But it may be thought necelfary here, to give a definition of what 
I call the living principle : fo far as I have ufed that term in this paper, I mean, 
to exprefs that principle which preferves the body from di Ablution with or 
without aftion, and is the caufe of all its a&ions.
