moving progrehive Particles of various Forms, fphe- 
rical, oval, oblong, and cylindrical, which advanced 
in .ill Directions fpontaneoufly, and were the true

other Kinds of this Nature, vegetate in a Manner 
analogous to this gelatinous Matter. See A/> 2

fiih Appearances, after an Exhalation of volatile 
Parts, as in. every other Infufion, were the fecond or

of the fmalleft and almoft in fenfible Parts, and which 
requird not fo long a Time to digeft as the more 
grofs. Thefe in a Day or two more intirely difap- 
pcared ; all was then quiet, and nothing to be feen 
but dead irregularly formed Particles, abfolurely 
unactive till about fourteen or fifteen Days after.
