Fig, 8, the back part of the same vertebra; aa the protuberances of the spinal process; b the 

 sinus between ihera, enlarged on the side; c the hole for the spinal marrow; d the point of the tooth 

 appearing from the other side; ee the holes for the cervical artery; f the concave body of the verte- 

 bra, which receives the convex surface of the following vertebra; gg tlie transverse processes; hh the 

 two oblique processes, which receive the oblique processes of the following vertebra. 



Fig. 9, 10, 11, 12, 13, 14., 15, l6, 17, 18, the five following vertebrae are represented by ab, 

 whereof a represents the fore part, b the back part; aa &c. the hole for the spinal marrow; bb &c. 

 their convex bodies, which are received by the concave surfaces of the following; cc &c, their con- 

 cave bodies, which receive the convex surfaces of the former; dd &c, the holes for the cervical 

 artery; ee &c. the oblique processes ; ff &c. the transverse processes ; gg &c, the spinal processes, 

 which in the fore part of the third and fourtli vertebrae, fig. 9> 1 1> scarcely appear, but in their back 

 part. Fig. 10, 12, appear a little, in 5, fig. 13, 14, arise to one inch and a half, and in 6", fig. 15, 

 l6, to three inches; hh, in 6 and 7, fig. 15, l6, 17, 18, are protuberances, which run back to guard 

 the cervical artery, as it passes from between the bodies of the vertebrae, and quits the perforation in 

 their transverse processes ; ii two sinus's in the back part of the seventh vertebra, which with the like 

 surfaces in the following form a cavity, into which the condyles of the first ribs are received. 



Fig. 19, represents the scapula; a, the head of the scapula, whereby it is articulated witli the 

 humerus; bb, the two protuberances on each side of its head; c the neck of the scapula; d a sinus 

 between the processus coracoides, and the neck of the scapula; e the processus coracoides of the 

 scapula; f the processus spinosus; g the extremity of the processus spinosus; h a protuberance run- 

 ning forwards from the processus spinosus; i the fore part of the upper edge of the scapula; 1 a thick 

 spongy epiphysis, which (at the upper edge of the scapula) was separated by boiling; m the angle at 

 the back part of the scapula. 



Fig. 20, represents the lower or fore part of the seven vertebrae of the neck; a, b, c, &c. the lower 

 or fore part of the bodies of all the vertebrae ; hh, the transverse processes, which run obliquely for- 

 wards ; ii, the transverse processes of the sixth vertebra, running both before and behind to guard the 

 cervical artery; k, a sinus in the body of the seventh vertebra, for receiving a part of the first rib. 



Fig. 21, represents the fore part of the ossa innominata; a the pelvis four feet six inches in cir- 

 cumference; B the OS sacrum; c the upper part of the os pubis; bc between the os sacrum and the 

 OS pubis, one foot six inches; de from the right to the left of the pelvis, one foot five inches; or, 

 from the upper to the lower part of the os ilium, one foot; gh, between the two outer extremities 

 of tlie ossa innominata, three feet six inches; bh from the os sacrum above to the aforesaid point, 

 two feet nine inches and a half; from h to k, one foot; l the circumference of the acetabulum one 

 foot six inches; eh the breadth of the os ilium one foot one inch; mm, the circumference of the 

 neck of the ilium, one foot two inches; nn the breadth of the os pubis, eight inches; oo, the 

 length of the foramen ovale for the musculus marsupialis, five inches and a half; pp its breadth four 

 inches; qq its circumference one foot one inch; rr the breadth of the os pubis before, one foot five 

 inches ; sx the length of the os sacrum, from where it is joined with the vertebrae of the loins, to 

 where it is joined with the tail. 



Fig. 22, represents the back part of the ossa innominata ; a the pelvis ; b the back part of the os 

 pubis at their articulation, where there is a large cavity; cc, the oval hole for the musculus marsu- 

 pialis fore- shortened; d the cavity for the acetabulum; ee the margin of the os ilium, which was 

 separated by boiling; p the back part of the ossa innominata, showing the spinal, and oblique pro- 

 cesses.
