fpine, which maybe called the aorta. As this approaches 
the upper extremity of the little animal, it is divided 
into fmaller and fmaller branches ; and in its courfe it 
diftributes lateral ones alfo to the contiguous parts of the 
trunk. Below the navel it fends off two branches tha.t 
conftitute the umbilical arteries, one of which is confi- 
derably larger than the other. And then below thefe, 
two other branches defcend to the inferior extremities^ 
A large umbilical vein comes in at the navel, and is im-

afcending, the other defcending. Each of thefe is again 
fub-divided into fmaller and fmaller branches, which,
