 fuch as really iffues out of the 

 pores ; for, as our fkin is always 

 covered with fome unctuous matter 

 which feems to repel water, the 

 fudden immerfion does not allow 

 the water to chace before it all the 

 air flicking, as it were, to the fkin, 

 but a good deal of it is left upon 

 it, and forms partly thefe large 

 bubbles. This feems to be the 

 more probable, as particularly thofe 

 places to which thefe bubbles ad- 

 here are found quite dry, if ob- 

 served attentively, when the part is 

 withdrawn out of the water. But 

 thefe very bubbles are in all proba- 

 bility alfo partly owing to air oozing 

 out of the fkin ; for, if they were 

 nothing but atmofpheric air, they 

 would not increafe in fize in cold 

 water, but become fmaller by con-
