1835.] On the Fossil Bones of the Jamna River. 497 



Specimens of Human Bones, sent Aug. 1834*. 



No. 1. Supposed to be the remains of the humerus, consisting of the 

 major part of the round head that plays in the cup of the scapula. 

 It was dug out from under a mass of clay at a depth of about 2 ft. 6 

 inches. 



No. 2. May either be a portion of the fibula, or of the ulna, of a child, 

 or woman : this I imagine may easily be decided by any anatomist. It 

 must be of considerable antiquity, as the tube originally occupied by 

 the marrow is completely filled with a hollow concretion or spar, 

 externally solid, and taking the exact mould or form of the concave 

 or inner figure of the walls of the bone. In the interior hollow of 

 this concretion a great number of very fine and sharp-pointed cry- 

 stals occur, with their points or vertices apparently pointing inwards 

 to a common elongated centre or axis ; from which it would appear 

 that the system of this concretion was either by the increase of the 

 crystals in size, or by their gradual projection from the exterior 

 inwards in a radiated manner, to fill up the cavity. This specimen was 

 found, and I have no doubt was petrified, amongst sand and shingle. 



No. 3. Portion of the above, supposed to have belonged to a full- 

 grown man. 



No. 5. One of the metacarpal bones. 



Nos. 46 and 47. Assimilate nearly with the 2nd and 12th dorsal 

 vertebrae ; but have belonged to different subjects. (?) 



No. 15. Appears to be a molar nearly perfect, and the remains of 

 another broken in its alveolus, with a portion of the jaw covering 

 each, and to have belonged to some of the larger species of deer. 



No. 17. Posterior extremity of a rib of a young camel, having the 

 same peculiar concretion as No. 34. (See postscript.) 



No. 22. A portion of the jaw of a camel, containing one of the 

 grinders. 



No. 34. The remains of the blade bone of the shoulder of a young 

 camel, remarkable for the peculiar cement or concretion filling its 

 cancelli, originally the depositaries of marrow. 



No. 18, (fig. 4.) Portion of the jaw of a pig, containing four grinders. 



No. 26. Extremity of one of the ribs, and No. 23, portion of the 

 plastrom or breastplate of the Cuchwa, or mud tortoise of the Jamna. 



No. 62. Portion of a rib of a buffalo, procured at a greater depth 



* We have thought proper to insert this notice, in continuation of the preced- 

 ing, as the specimens referred to are deposited in the Museum, and have heen 

 imagined by more than one person to he human. See the following note.
