furrounded with a watry flimy Matter, and that Matter 
inclofed in a Skin or Membrane, and that Skin burfting

I have made my obfervations more than once of the 
aforefaid AnimalcuU in feveral Cod-fifh, even in the Male 
Seed, wherein I Httle expefted to meet with living Crea- 
tures, becaufe fuch Seed was not newly coming away 
from the Fifh) but {queez'd out of the Vaf^ DefcreritU^ 
and exceeding thick, like that which iffues from thcFilh 
when they throw him down on the ground, and have 
.difcover^d an infinite number of exceeding fmall Creatures 
(and fmaller than I ever thought they were ) aliveT and 
fvvimming together, and viewed them often fo long till 
the liquid Matter in which they fwom was quite exhaled, 
and the AmmdatU dead, and where they were a little 
difperft, they - were burft -afunder ^ Jbjut where .they lay 
thicker and clofer together, . J could not percei ve^the brokea 
pieces of their bodies. ' ; . • - . j ' . ' ri-.'c:::

That I might reprefent to you thdir fmallnefs, as well 
as I could, I . took one of the Hatrs of my .Head, and 
placed itnear thofe Creatures. This Hair was flat, as 
moft of mine are, and the fiat fide thereof was next my 
fight, and anybody that xvere to look upon that Hair, 
and the AnimalcnU together, would cafily judge by their 
£ye, that 90 of thole Creatures did not exceed the Dia-
