of a Filament fo fhort as not to conftft of above 
four or five Globules Chaplet-wife ; they would ad-

irregularly to one Side, as if not yet fitted for progref- 
ftve Motion, languidly turn their Extremities, and 
then again lie quiet for fome little time. It was my 
Fortune however, not in this Infufion only, but in 
many others, to find fome of thefe Chaplet-like Ani-
