 However, in two years, having procured an ex-

 confequence could not correfpond more with M, 

 de Sauffure's refults. 



The animalcula were firft expofed to the dif- 

 charge of the Frankiinian battery. Upon it was 

 put a little fpot of pitch, with a very fmall hole 

 through the centre, full of infufion j the fpark 

 was drawn through this hole. Not one animal-

 a moment ; many were wounded and reduced by 

 the eleftric vapour, and many appeared untouch-

 battery lefs, but the effect was the fame. The 

 quantity of liquid expofed to the ftiock was en- 

 creafed, by drawing a right line on the fpot, twa 

 thirds of an inch long, and two lines broad, pro- 

 ceeding from the central hole. Then the diock 

 was tranfmitted through the whole fiuid. It was 

 a real thunderbolt to the animalcula ; all immedi-

 creafed but not the length, a change enfued. So 

 long as only two lines broad, none efcaped, but 

 when morfe than that, the animalcula either were 

 not injured or did not die for fome time. Thofe
