■ Vertebra (correfponding to the Rib) in toward its Body: After 
!wh eh a Wire two Inches long was faftned in the Body of the 
Vertebra , and Excremity of the Rib, and then both were 
brought together ^ which being done, the Wires were put into 
their refpeffive Holes in the tranfverfe Procejfes and Ribs, and both 
the ends of each of the two lafl Wires, being brought together 
at the upper part and Interftice betwixt the Ribs and tranfverfe 
Proceffes , were twilled and made firm. Thus I continued to do 
throughout all the Nineteen Pairs. 
t A v in- . After this 1 provided fome Jumps, or Leather, fuch as Shoe^ 
Car- rriakers ufe for the Heels of Shoes, becaufe the Bend or Sole 
Mares. Leather us'd in mounting the Sceletons of other Animals, could 
k * not be fo conveniently fitted as to its thicknefs. Having wetted 
and beat this Leather, it was (hapen’d according to the bignefs 
of each Vertebra, perforated in rhe middle, and put upon the 
Rod alternatively, firft the Vertebra, and then the Leather, to 
fupply the defect of the Cartilages, which were all loft in boiling, 
as ufually happens, and was beat fo dole, that the oblique Pro- 
ceffes of the Vertebra might meet. This was continued till all 
the Vertebra were upon the Rod, all aloDg to the Os Sacrum ; 
and becaufe the firft Vertebra is nothing concern’d with the Rod, 
'twas convenient to pals a Wire betwixt the Scull and it on 
each fide, that it might not remain loofe, but be fix'd to the 
Condyles, by twilling and making fall the Wire. 
I came next to the OJfa innominata, which had been disjoin’d 
Connexion in Boiling, both before or below at the Os Pubis, and above or 
of the Ofti behind at the Os Sacrum. 1 made two Rods of Iron to pafs 
Innominata* tranfverfely from the one fide the one above, and the other be- 
low ) through the Os Sacrum to the other. Thele were riveted 
on the back fide at both ends •, and then having erforated the Os 
Sacrum from above to below through the middle of its Body, 
it was alfo put upon the Ro 1 for the Spine, which was a very 
difficult Task, becaufe the Rod being thick was uneafy to bend, and- 
the Situation of the Os Sacrum requir’d it to be bended precisely, 
betwixt the lafb of the Vertebra Lumbar um, and the Os Sacrum. 
Neither was it eafy to perforate the Os Sacrum itfelf, being ob* 
liged to make a Drill on purpofe, there being no other Bone in 
the Body that requir’d one fo long. After this I proceeded to 
put on the Bones of the Tail, and their Sham Cartilages alter- 
natively, as they followed in order, till all the Rod was fill’d,
