magnifier, nothing could be difcovered on ac- 

 count of its opacity. It began to diflblve ; and, 

 lofing thewhitenefs, acquired the colour of foapy 

 water. It was again examined with a magnifier 

 of fmall power ; the irregular parts feemed to be 

 in an indiflind flow fermentation. With the affift- 

 ance of a much more powerful glafs, 1 obferved 

 that thefe parts were moved by corpufcula, -infi- 

 nitely more minute, of a globular figure. Eacii 

 had a fort of filament or fliort appendage, PI. 2* 

 iig. I . A. The groffer part of the fluid was evi- 

 dently put in motion by them, for there was none 

 when they v/ere at reft. The corpufcula them- 

 felves had two . motions ; one ofcillating from 

 Tight to left and from left to right, curving the 

 appendage from one fide to another ; the other 

 was progreflive, advancing by means of ofcillationo 

 During this, one would fuppofe them blind: 

 they ftrike againfl every obftacle ; and, when 

 amidft a number, make agitations and contor- 

 fions, at laft, taking that way where there is 

 leaft refiftance. They are reftlefs and continually 

 moving. 



in twenty-three minutes the ofcillation and pro- 

 grefllon had diminifhed ; and it had leflened fo 

 much in an hour and a half, that very .few cor- 

 pufcula prefer ved any appearance of motion. The 

 progreflive motion generally ceafes before the 

 ofcillatory, fo that the corpufcle at laft merely 

 'bends from right to left, and reciprocally. They
