with very fhort cilia.
It is o f the number o f the larger animalcula, the body is cryftalline,
and replete with black molecules, it’s fkin is perfectly
fmooth and colourlefs, it’s hinder extremity is rounded, the anterior
is truncated; there is a large opening vifible at this extremity,
which ferves as a mouth ; this is thickly ciliated.
