It had two large Ventricles and as many Auricles. To- 
wards the Cone the Ventricles feemed a little divided. 
The valves of the Ventricles and of the Artena Pnlnw- 
ndis and Aortx were not different from thofe in Qua- 
drupeds, but the Ca.Ynm Cohmn^ in the left Ventricle 
were larger and more numerous and curioufly interwo- 
ven lattice-wife. 
The foramen ovakv^2.^&(&di and not open \ where it 
had been, we could perceive by its tliinnels and tranfpa- 
rency. We did not think of it then to look for the Camt- 
Us Artmoftis^ but probably its paffage may be likewile 
fhut, as is alio the foramen o'vde ip a Beavor and an Otter, 
as it hath been obferved by fbmc at {n) Paris ^ though 'tis 
delivered by others that in thefe Amphibious Animals 
'tis kept open, that they may be the better able to keep 
under water, the Circulation of the bloud being conti- 
nued by this means without being tranfmitted into the 
lungs as it is in the Embryo's of Quadrupeds in Vtero.

off, the minute ramifications of the Sanguinary Vefleis 
were very pleafant to behold. The Parenchyma of the
