an hour, has been loft, it is moft probable that this will 
not be Sufficient; the heart, in all likelyhood, will by this 
time have loft its nice connection with the lungs. It 
will, theiefore, be proper to apply Simulating medicines, 
fuch as the vapour of volatile alkali, mixed with the air; 
which may eafily be done, by holding fpirits of harts- 
horn in a cup under the receiver of the bellows. I would 
advife the air and volatile alkali to be thrown in by the 
nofe, if by both noftrils fo much the better, as we know, 
that applications of this kind to the olfaClory nerves 
roufe the living principle, and put the mufcles of refpi- 
ration into aCfion, while fome applications to the mouth 
rather deprefs than roufe, by producing ficknefs. If 
during this operation the larynx be gently preffed againft 
the cefophagus and fpine, it will prevent the flomach and 
ifiteftines being too much dilf ended by the air, and leave 
loom loi the application of more effectual Jltntuli to thofe 
parts. This preffiure, however, mult be conducted' with 
judgement and caution, fo that the trachea and the aper- 
ture into the larynx may both be left perfectly free. 
While this bufmefs is going on, an affiftant fhould 
prepare bed-cloaths, carefully brought to the proper 
degree of heat. I confide!* heat as congenial with the 
living principle; increafmg the neceffity of aaion it in- 
creafes aaion; cold, on the other hand, leffens*the ne- 
ceffity, and of courfe the aaion is diminifhed ; to a due 
proportion ol heat, therefore, the living principle owes 
its vigour.
