ITS thickest spongious Part (properly call’d the Placenta) adheres to the Bottom of the Womb by innumerable Vessels, and the Interposition of a very thin Membrane, which is a Continuation of the Chorion.

ITS Concave Part towards the Infant, is join’d to the Navel-String, and encompass’d with a smooth Membrane, which it derives from the Chorion and Amnion.

THE Vessels terminating in the Navel-String, are inserted at one End, almost in the Center of the Placenta; as the other End adheres to the Navel of the Infant.

THE SECUNDINE is rough and unequal on the Outside, and smooth and soft on the Inside; and cannot be extracted, without breaking the mentioned Vessels: From hence an Effusion of Humours and Fluxion of Blood always follows it; which (according to the Woman’s State of Health) is of a fairer, or darker, red Colour.

THE Use of the SECUNDINE, is to receive and absorb the Nutritious Juice from the Womb; (as the Intestines imbibe the Chyle) which it afterwards transmits to the Infant, by the Umbilical Vein.
