chang’d, for whereas it formerly reach'd from before to behind , 
now it reaches from the right to the left, and its lower extre- 
mity (4) becomes broader, whereas at its upper extremity it was 
rounder. 
The Cubitus and Radius are two Bones of a lingular Fi- The Cubitui 
gore, the one lying above the other: We Ihall begin with and Radius, 
the Cubitus , which is in length from the top of the o - 
leer anon to its Articulation with the Bones of the Carpus 
(?) 28 Inches. The Olecranon (jJ from the right to the left, 
with a Surface fomewhat convex, is 9 T Inches^ and from be-xhe oiecra^ 
fore, where it is articulated with the Humerus , to its utmoft point n0 n. 
behind, in a ftreight line 7 Inches. This Olecranon as it defeends, 
becomes narrower by degrees, till it forms a Spine, which runs ob- 
liquely forward 13 Inches, where ’tis contra&ed from the fore- 
laid 9 y Inches to 3 in breadth. Afterwards the Bone is en- 
larg’d on each fide, till it forms a convex Surface, which is re- 
ceived by, and articulated with the Humerus.Thh Articulation is a 
Ginglymus , as in all other Animals* viz., the Cubitus and Radius 
together receive the Humerus on the outfide before, which on the 
infide the Cubitus doth alone. Betwixt thefe two is a large Pro- 
tuberance riling 2 5 Inches, which is alfo received by the Hume J 
rus. Meafhring from the extremity of the Cubitus and Radius , 
which receive ^he Humerus , on the outfide to its oppofite part on 
the infide, including the back part otthe Qlecr anon is 10 Inches. 
Both the Bones from the right to the left, at the articulation be- 
fore, are 7 Inches. Then meafuring round the Cubitus , below the 
Articulation, is 16 i Inches. Here the Bone is flat before, from 
the right to the left 7 Inches •, from thence obliquely backward 
to the forementioned Spine beneath the Olecranon is 5 Inches on the 
outfide, and 6 j on the infide. At the lower part of the forelaid 
Spine the Cubitus is in Circumference 1 1 Inches-, viz., flat before 4 
Inches, where it forms an Angle ^ thence running obliquely back- 
ward 2 Inches, forming another Angle •, thence 1 \ Inch ob iqudy 
backward, where ’tis a little Protuberant ; and from thence ob- 
liquely inward 3 ^ Inches. Round the lower extremity of theC«- 
bitus, and 3 Inches above the Epiphy/is, it is 12 Inches j viz. f om 
the Radius 2 j Inches ; thence obliquely outward, with ano- 
ther flat Surface, 3 \ Inches *, and from thence, with a convex Sur- 
face, round the back part 6 Inches. The Cubitus at the Epiphyjis > 
from the Radius on the fore part to its oppofite fide on the back 
part, is 1; Inches i from the upper part of the lower Epihyjis, where
