deny that man himfelf may fometimes be in a fi- 
milar fituation with animals overcome by cold, 
as when he has been immerged in water, without 
entirely ceafing to live. I will not affirm with 
fome philofophers, becaufe there is neither pulfa-

of this we have in fome animals half drowned, 
where a degree of motion is always fenfible in the 
heart and in the blood. The life of man and 
animals half drowned cannot be more feeble ; 
and we may regard it as another point in the paf-
