Laft Sammer I open'd the Seminal Veffels of a young 
Cock that was newly kill'd, pluckt, and ftill vvafm ^ in 
^v^hich riikewife difcover'd thefe Aniwalcula (iWl hvmg ^ 
nnd they remained alive for the fpace of halt an hour after 
1 had fqueez'd a Drop of the Seed out of the faid Veffels. 
I was forimrly of opinion, that the AnimalcuU in Se^ 
wine Mafculino of a Cock (as they then appear'd to me, 
hoth fvvimruiog in their Fluid Matter, as alfo after they 
were Dead)'were in Shape hke our River- Eels, but by my 
late Obfervations I fiRd I was miftaken in my Thoughts 3 
for now they appear, both in motion and when they lys 
-fiill, as if the fore^part of their Body were crooked or 
Circular. 
Not content with my own Obfervations; r took a great 
deal of pains to give the Limnef a Diftinft View of them 3 
which happened very well, and is as follows. 
Tab.i.Fig. i. ABCD Reprefentsoneof thofelittleCrca- 
tiires in its whole length^whtrcof ABC is the Body,which 
is feldom quite ftraight, but the Tail moftly folded 3 and 
that w^as the occafion of my error y jfor when I view'd 
them formerly, I thought I had feen their whole Body, 
whereas I now difcover'd a long, ami exceeding fmall Tail^ 
which fe (bown by C D* 
Thefe Tails were fo wonderful fine, that I had much 
ado to make the Limner perceive them, for by reafon of 
their fmalnefs, they often efcape the ftiarpeft fight. 
In the fore-part of the Bodies of many of thofe Ani- 
malcuU I difcover'd a clear bright place, which was not to 
be feen in others ^ and the Tails of* all thefe httle Crea- 
tures that lay dead were fo many Bows, which I caus'd.the 
Limner to defcribe in Tab. 1» Fig. 2. 3. 4. and 5. - ' 
From hence, I luppofe, it is, that when I mentioned ' 
the Animaicula in Semine Mafculino of other Creatures," I 
took no notice of their long Tails, which without doubt 
(bey were provided with, as well as thefe in the Seed of 
young Cocks^
