ME. ST. GEOEGE MIYAET ON THE SKELETON OE THE PEIMATES. 
Fig. 4. Femur of Mycetes (from the same skeleton as the scapula and clavicle were 
taken from), showing the very gradual increase downwards of the transverse 
diameter of the shaft, &c. 
Fig. 5. Posterior surface of the upper part of the femur of Hapale, from the skeleton 
No. 4666 in the Museum of the College of Surgeons. 
This shows the wide space between the trochanters behind. 
Fig. 6. Outer surface of the os calcis of the Gorilla (5179 a.q. College of Surgeons), 
showing the deep groove outside it, and the very prolonged tuberosity, with 
the strongly marked inferior concavity of the bone. 
Fig. 7. Astragalus of Gorilla (No. 5179 a. r. College of Surgeons). 
This shows the great breadth and shortness of the bone, and the surface for 
the tibial malleolus (t m) almost in the same plane with the surface for the 
shaft of the tibia. 
PLATE XIV. 
Fig. 1. Dorsum of the carpus of the left manus of Troglodytes niger, from the specimen 
No. 5083 A. in the Museum of the Royal College of Surgeons. 
In this the scaphoides (sc.) is large, and sends a marked process over the os 
magnum (mg.). 
Fig. 2. The same view of the same part in the Orang (No. 5076 in the same Collection). 
Here the scaphoides (sc.) and the intermedium (i) seem together evidently 
to answer to the scaphoides of the Chimpanzee. 
Fig. 3. Trapezium of Troglodytes niger from the mounted detached manus in the 
Museum of the College of Surgeons. 
In this there is no trace of a concavity for the metacarpal. 
Fig. 4. Trapezium of Nycticebus tardigradus, from a specimen in my own collection. 
(Four times the size of nature.) 
Fig. 5. Palmar surface of right carpus of Perodicticus, from the specimen in the British 
Museum. 
Sc. Scaphoides. 1. Lunare. c. u. Cuneiforme. pi. Pisiforme. u. Process 
of unciforme. tz. Trapezium, x Extra ossicle placed between the unciform 
process and the very large process of the trapezium. 
A bristle is represented passing through the arch formed by the extra 
ossicle and these last-mentioned processes. (Twice the size of nature.) 
Fig. 6 Distal surfaces of the human carpal bones. 
Fig. 1 The same view of those of Macacus. 
Fig. 8 Distal surfaces of the human tarsal bones. 
Fig. 9. The same view of those of Macacus. 
These five figures exhibit the correspondence between the angles formed 
by the articular surfaces in the manus and pes.
