Spawn. In fg. 2. towards the Tail, the 
Spawn Bags (at leafl what I believed fuch)

other Figures, but no Spawn was difcovered 
in them * and fince thefe Drawings I have 
examined more of the Pediculi aquatici , and 
find the Spawn fixed to the Tail much lower 
than thofe Bags, and adhering to the Tail by 
two fine Ligaments, which are eafily broke 
by the Infed’s ftirring itfelf in the Water ; 
and fometimes all the Spawn comes away 
flicking together, but oftener feparated and 
difperfed among the Water. But though I 
have kept the Spawn fome Time, I never 
could find the young Infeds in the Water, 
which Leeuwenhoek fpeaks of ; but perhaps 
I have not had mine when the Spawm was 
come to an equal State of Matriuty. I have 
fent you this Account, becaufe the former 
Figures of this Infect have been extremely 
imperfed in all Refpeds, except the Spawn,

received that this Infed varied from all others 
in being monoculous .

its two Bags of Spawn adhering to its Tail, (as may be feen
