41 6 Mr. hunter’s Propofals 
Now, the prefent confideration is, which of the kinds 
of violent death drowning comes under r I think, it 
comes under the firit; and upon that ground I fliall con- 
lider the fubjedt. 
The lofs of motion in drowning feems to arife from 
the lofs of reipiration, and the immediate effects which 
this has upon the other vital motions of the animal ; at 
leaft, this privation of breathing appears to be the lirft 
caufe of the heart’s motion ceafing; therefore, moil pro- 
bably, the reftoration of breathing is all that is neceffary 
to reifore the heart’s motion : for if a fufficiency of life 
Hill exiils to produce that effeff, we may fuppofe every 
part equally ready to move the very inftant in which the 
action of the heart takes place, their actions depending 
fo much upon it. What makes it very probable, that 
the principal effecSl depends upon air being thrown into 
the lungs, is, that children in the birth, when too much 
time has been fpent after the lofs of that life which is pe- 
culiar to the foetus > lole altogether the difpolition for the 
new life. Ill fuch cafes there is a total fufpenlion of the 
actions of life, the child remains to all appearance dead, 
and would die, if air were not thrown into its lungs, and 
the firft principle of adlion by thefe means reftored, To 
put this in a ftill clearer light, I will give the refult of 
fome experiments which I made, in the year 1 7 5 5, upon 
a dog. 
A pair of double bellows were provided, conllrudted 
in fuch a manner as by one adtion to throw frefh air into 
the lungs, and by another to fuck out again the air which
