 than the rest; 3 the third vertebra having scarcely any spinal process; 4 the fourth^ whose spinal process 

 is not yet seen ; 5 the fifth, with the spinal process beginning to appear ; 6 the sixth, whose spinal 

 process ascends higher, and is remarkable at its fore part, as in table 4 ; 7 the seventh, whose spinal 

 process still ascends, and with whose back part the first rib is articulated ; c the vertebrae of the back ; 

 1 — 13 their processus spinosi, which have no protuberance at their extremity, whereof 1 — c

 vertebrae to the os sacrum which are shortned by degrees ; xxxxx &c. the oblique processes of the ver-

 the sternum ; iii the three ribs which have no cartilages ; 111 the bodies of the three vertebrae lum- 

 borum ; f the humerus ; 1 its upper part, spongious and rugous, for the insertion of tendons ; 2 its 

 middle part more solid ; 3 a large oblique sinus for lodging the biceps ; 4 its lower extremity articu- 

 lated with the cubitus and radius ; G the cubitus and radius ; 1 the olecranon ; 2 a hoUowness on the 

 outside of tlie cubitus ; 3 the radius ; 4 its lower epiphysis, rugous, and separated from it by a 

 suture ; 5 t'e lower epiphysis of the cubitus, separated likewise by a suture ; 666 three bones of

 part of the os palati, over which hangs the proboscis ; cc a depression of the bone on each side, for 

 lodging of the muscles of the lower jaw ; dd the two eminences on each side at the top of the head; 

 e a depression in the middle betwixt these two eminences ; ff two beginnings of the angles for form- 

 ing the depressions for the muscles of the lower jaw, between which the surface of tlie bone begins 

 to be plain ; g the upper production of the sinus where the eye is lodged ; h the beginnings of the 

 laminae which run between the two tables of the skull, and here appear in the bottom of the hole 

 for the root of the proboscis ; i the os vomeris, to which the cartilaginous septum of the proboscis 

 was adherent ; k the beginning of the depression of the os palati ; 1 the middle of the sinus for the 

 orbit of the eye ; m the articulation of the two ossa-palati ; nn the articulation of tlie os maxillae 

 with the OS palati ; where also is a crena for containing the blood vessels, as they go to the nourish- 

 ment of the proboscis ; oo the place where the tusks proceed from the os palati ; pp the upper part of 

 the articulation of the os maxillae with the os palati ; qq the broken extremities of the tusks ; rr a 

 great oval hole in the os maxillae, through which a considerable branch of the fifth pair of nerves, 

 and a large artery from the arteria durae matris pass to and are dispersed in the proboscis, and by 

 which a laro-e vein returns and joins to the vena jugularis ; s the os zygomaticum ; t the middle pro- 

 duction for the orbit of the eye.
