Mafs of the circulating Fluid. 
In order to view the Pores , cut a Slice of 
the upper Skin with a fharp Razor as thin 
as poffible : then immediately cut a fecond 
Slice from the fame Place, which apply to 
the Microfcope, and in a Piece not larger 
than a * Grain of Sand can cover, innumera¬ 
ble Pores will be perceived, as plainly as little 
Holes pricked by a fine Needle may be dis¬

Scales of the outer Skin prevent any difiind:

the Fingers, or in the Palms of the Hands, 
be fo prepared, and then examined, the 
Light will be feen very pleafantly through 
the Pores . ■
