1 a Dog, as I faw it fwimming. 
Fig. :4.. IKJ^^ isoneotthe Animals when its dead. 
I have often obferved thefe laft Animals to change their 
. figure, ehiefly when the inoifture wherein they live, and 
- iwim, is exhaled. 
V When one of thefe Animals has got fo far in the 
Womb, that it finds a place fit to nouriihit, then may it 
fuddenly caft off its Tail, or its whole outward covering, 
and remain of an Ovall form, as Fig* 3, FG H* ot Fig^ 4. 
. ; Again we find that the^ Bodys of Animals, whilethey 
are in the Womb, are fo bound together, that they ap- 
pear round. This is daylv leen in larger Animals, and 
is undoubtedly the lame in Infects. 
Ilikewife am perfwaded, that no Animal is changed 
v orcafts; his Skin, without there be another Skin left to 
cover his body. This wefind in Cater-Pillars, which as 
foon as they are come to their growth, and have fpua 
their Cafe, they change not only their firft Skin, and be- 
come a C/'ry/^/^jr, but are yet encompaffed with another 
, Skin 5 and thus I believe it is vf ith, x\\^ Animali a Seminis 
>. Mafculi, for they no fooner loofe one of their Membrance 
OT Coats, but there remains another, which continual- 
ly incompaffes the Fcstus, and grows together with it, till 
• it comes to a Birth. 
Its fuppofed that Animals while they grow in the 
Womb, have a living Soul ; now if this be fo, its a thouf- 
and times more likely, that the Soul which is in the jini^ 
maliaSeminisMafcuh Ihpuld fl:ill remain there, chang- 
ing only their outward fliape, then that they fhould pafs 
into another body. 
I am alfo perfwaded, that the living Soul which is in 
an Animal of the Semen of a Coc\y does not loofe it felf in 
the parts of the Egg;but the parts of the Egg pafs into the 
living Animal ; lo that the Egg of the Hen ferves only 
to.noiarifh and feed the living Animal. like-
