Thus having traced the Generation of our Infefl-, 
Uuough its fevcral ftages, and finding it to be ^sfolenm 
and regular as any in Nature, even as that of an humane 
FfKtus it felf, I cannot eafily pafs over the bufinefs ot 
Mqnivocal Oemrdtion without a rcfledion. If this Infeft 
was ever taken notice of by the Ancients (as I do not find 
it was, either by them, and but little by the Moderns) 
they would, no doubt, have made it^ Produdion to be 
(like that of other Infefts, vizS) out of Duft, or fome 
other thing, in which its Eggs were laid. But as in this, 
fo in the Generation of all other Infefts, yea all Animals, 
it hath been obferv d, that Nature is very regular, and 
uniform, in deriving the OflP-fpring, not from corrupted 
Matter, but from Animal Parents of the fame Species. The 
Digreffion would fcarce be pardonable, or I (hould hard- 
ly forbear expatiating on what I have often with great 
Pleafure and Admiration feen of Natures procedure in the 
Generation of Infedh particularly 5 as for infVance, Gnats. 
'Tis wonderful to fee in what curious and exaS: order the 
feveral Species of Gnats lay their Spawns- The curious 
and ingenious Six^ammerdam, and other x'Xuthors mention 
but two kinds of Gnats, but I have coUeftcd near 30 
diftinft Species of them, and have obferved one Species 
to lay its Eggs in this, another in that, another in a third, 
and others in other Forms ^ and I could not but admire 
to fee how artificially t^e Spawns are tied in the Water ^ 
how (after the Suns Iccubation, if I may fo call it) the 
Spawn is diffolved, and the Eggs, with a part of the Gelly 
in which they were inclofed, fall to the bottom of the 
Water, and there fcick on Stones and other things^ where 
they are hatched into Njmph£^ .as various as the Gnats 
thejmlelves, fome being red-, green white or other coloured 
Worms, fome of quite a different Shape ; and iaUly, how 
thefe Nywph^ htcom^ Aureli^^ and then Gnats, hoi\\ Male 
and Femde of every Species.
