enter thefe minute Veftels. What fhaii we now 
fay ? Why, in regard to the Memory of this great 
Man, to whom the World, and this Society, are 
much obliged, I muft inftft, that he certainly had 
Glaftes, that were much greater Magnifiers than any 
we have of his. 
It may perhaps be obje&ed, that Mr. Leeuwenhoek 
declares, he did not ufe fuch Email Glaftes as fome 
People boafted of ; and that, although for 40 Years 
together he had been poftefted of Glaftes exceedingly 
minute, he had employed them very feldom; fince, 
in his Opinion, they could not fo well ferve to make 
the firft Difcoveries of Things, as thofe of a larger 
Diameter. In Anfwer to this, I muft beg Leave to 
obferve, that Mr. Leeuwenhoek , in this Place, is 
refledting on a certain Phyfician, who boafted of an 
extraordinary { Microfcope fcarce bigger than a vifible 
Point, whereby he pretended to difeover the Ani- 
malcules in Semine ‘virili to be cxa&ly of an human 
Shape, with only a Skin over it. For he fays, that 
while he was attentively obferving xhzfe Animalcules, 
one of them (a little bigger than the reft) prefented 
itfelf, having almoft flipped off its Skin : And then 
there plainly appeared Two naked Thighs and Legs, 
a Breaft, and Two Arms, above which, the Skin 
being thruft up, covered the Head as it were a Cap.
