whllft the globules were ftill in motion, with a 
fphaerule that magnified the diameter 1920 times ; 
and in this view the globules appear’d fo clearly to 
be hollow rings, that there was not room for the 
lead fufpicion of the reality of the fadt from any 
circumftance. The diameter of the perforation ap- 
peared much larger in proportion to the thicknefs of 
the circumference than it had done in the former 
views. The figure of the rings, where they were 
free, and in their natural date, was circular ; but 
where they were fo crouded together as to comprefs 
one another in their pafi'age, they afilimed a variety 
ot diderent figures, although they generally redored 
themfelves to a circular figure again, unlefs broken 
by the comprefiion which frequently happened, and 
then the broken parts floated fcparately; or, if they 
opened at a fingle joint only, the whole of the ring 
would float along, varying its figure occalionally 
from that of a portion of a circle, which it would 
fird aflume, to a draight line, an undulated one, or 
fome other accidental incurvature. The articulation 
was vifible in feveral of the perfedt rings, but for 
the mod part it was not to be didinguilhed, tho’ 
even in thefe, from their breaking fo eafily, it was 
not to be doubted but that they confided of the 
lame detached members or joints as thofe in which 
the tranfverfe divifions were vifible. 
Upon applying afterwards magnifiers of lefs power 
to the fame blood, the greater advantage of light 
made the rings appear dill more perfedt and didind^j 
but as thefe were not applied till the globules had 
lod their motion, and the whole drop had grown 
dry upon the talk, tlie divifions at the joints were
