which will continue until a greater Quantity of Spi- 
rits be recruited, than is confumed in the natural and 
vital Functions ; at which time the Redundancy or 
Overplus begins again to be fecerned into the other de- 
ferted Nerves, to wit, into thofe of Senfation and volun-

nied, that if there is fuch a Fluid as animal Spirits, 
they muff be the fined and mod depurated Fluid of 
the Blood x Thefe therefore will be abforbed, and
