they draw themfelves back on a hidden towards it, and 
then ftretch out again very flowly. 
In the leaf! drop that could be taken up from the 
third glafs, wherein the leaves, ffalks, and roots were 
mixed, was fuch an infinite number of thofe little ani-

and frequently turns itfelf upfide down. 
Amongft other infufions of celery, was found an ani¬
