In the /i&/r<af Chapter, xht Mefnbranes a/id Hmors of Emhrj&'s are 
confidered, The iifd'/^^w^^i are in fome, three, in others, four, in an 
Egg, fix. All lidcemiferm Anioials (ii 1 may adume this word) he 
affirms to have three MemhramSy and Sem^ Mares^ and Women alfo 5 
but only v^o H^mors^ h^^m^Biichcs^Cm^^L^^ Conies ^hm Membranes^ 
and three Humors fo that the Number of the Membranes hath been 
hitherto obferved alwaies to exceed that af the Hrmw, 
Giving the Hillory of both, he begins from Skej>^ Ccws^ and other 
Rumhdthg Animals, defcribing/// the Chorion ^z&gmng ksUfey and 
comparing, it with that in Deer^ SewSy Mares , W^men^Rabbets^ Baches^ 
and C^//^ when with young. Then he proceeds to the defcription of 
tht ^iOam^jies ' the Membrane immediately encorapaffing that skin, 
wherein t- e Fcems is wrapped j and thence to that of the Amnion^ 
whereifithe Embryo itfelflieth, fwimmingin its alimental liquor. And 
lajtly to that which is obferved to be in Bitches ^ Cats^ and Rabbis ^ and 
contains a very good and nourifhing Juyee 5 which how it comes 
thitfief^ 'k a difficult inquiry, as well as that other'j how the liquor gets 
into the Am^^iow, To refolve both which our Am hor, having difpro- 
ved the Filer ation of the liquor, held by Cnrvej and Bverhard out of 
the c'A^/w? into the Amnion^ and evinced, that the liquor in the Al-^ 
lantoidesy inter je(Sted between thefe two is Urinons^ he concludes, that 
the alimentary Juyce paffes through the Umbilical Veffelsby a proper 
Arterjy depofiting it in thofe Membranes we fpeak of^ and referving 
it there for the ufe of the F(^tn$, 
Co earning the Humors ^ he affirms^ that all of them in all Animals 
are NHt-itive, except that in the Allantoides, He obftrves alfo, that 
moft of (9t^i/^4r^'iijx Pifheshave Eggs or Spawn, as tofenfeof one only

fible, vtz . a Yoik and a double White : to which upon incubation, 
comes a fourth, coiliquated our of the former ; the tender Embryo 
feeding upon the two Whites, till they being confumed, t! c Yolk cf 
the Cbck now to be hatcht, is (hut up in che Ahdomt:?'^^ and thence by 
a peculiar Df4^us convcighed into the guts y and fo icrves the young

In Fivifarous Creatures are found fometimestwo, fometimes three
