Wh^tConffienct thefe Bodies fometimes acqmre,this a- 
bove defcrib'd is a very inftrudtive inftance. The clofe fi- 
brous texture, the tough Membrane that covefd it, and 
the two black hard fpecks therein included, its ftrong 
adhefion to the heart by little capillary Roots and o- 
ther larger protuberances adapted to all the little cavi- 
ties of the Ventricle, are arguments that it was no fmall 
time in growing ; and if it happen'd after death, how 
came it to pafs that the large branch 5. ftiould flop with- 
in the Auricle, and that nothing of the lihe Jubjlance 
fhould be continued farther into the Vena Cava, fince the 
Blood there muft needs be as much difpos'd to fuch a fud- 
den coagulation as in the heart; but it will be eafie to 
account for this circumftance if we lay the firft Rudi- 
ments in the heart, allow them to grorv by a daily appo- 
lition of f refh parts, and that growth conftantly to be cir- 
cumfcrib^d by the AppuHe of Blood, or by the adlion and 
labour the Auricle, wherein this branch foodlyftiap'd 
was contain'd. Laftly , if to thefe remarques we add the 
IxA^ncQ Malpighius gives of a Polypus made hallorv by the 
current of theBlood,like another new blood-veffel fram'd 
with the natural one ; If alfo we add another round one 
5^r^//a/fpeaks of, bigger than a m ans jfift, found in the 
Aorta near the heart, confifting of a great many mem- 
branes lying unconnext one upon another , like the 
leaves of a Cabbage, [a produSl (without doubt) of no fmall 
time) we need go no farther than the bare accidents of 
theleodd bodies themfelves to prove their long continuance 
before death.
