they grow gradually higher and higher on the Spinal, 
forming two cheeks, into which is received the back of 
the anterior Ipinal proceft. 
Befides thefe procefTes already mentioned below the 
Abdomen and oppofite to the Ipinal proceffes, I find 
* others not arifing from the vertebra themlelves, but 
that Cartilaginous body that joyns the vertebra toge- p p * 
ther. They confift of two fmall bones joyned toge- 
ther at the end, but diftant at the bales, lo occafioning 
a hollow, through which there runs abundance of 
bloud-veffels ; as the Medulla, Spinalis does in the Ca- 
vity of the Spinal proceffes. Thele precedes, as do all 
the other, grow leflfer as they approach the Tayle till 
they are quite obliterated. Where the Tayle or hinder- 
fins are fattened, the vertebra do proportionably leflen 
and do grow broader and lels round. The vertebra are 
joyned together by the intervention of a bony Cartilagi- 
nous body thatconfifts of a double Lamina , containing, 
in a Cavity in the Middle, a gellied lubftance. This is 
atr excellent contrivance for the fleftion of the body, 
for otherwife the vertebra themfelves are too rigid for 
fuch a motion. 
I have before mentioned that there were thirteen 
f Ribs, that only five were fattened to the Sternum , that \ ss s. 
the fixth and leventh had Cartilages , but not continu- 
ed to the fternum ; how that they role obliquely from 
the Spine, &c. I fhall add that the firft five Ribs, that 
were continued to the Spine, had a double originati- 
on • the firft to the extremity of the tranfverle pro- 
ceft of a hinder vertebra, and the lecond to the bafis 
of a former. The other Ribs were only fattened to the 
extream of the tranfverle or Lateral ProceflTes. The 
thirteenth or laft Rib did arile only with a Cartilagi- 
nous Origination, and afterwards became long. And 
whereas the os Pectoris or Sternum , and that which con- 
tinues the Ribs in other Animals to the fternum, is ulual- 
ly Cartilages, here ’twas ali perfebl bones.
