498 On the Fossil Bones of the Jamna River. [Sept. 



(about six feet) under the clay than any specimen in the collection. 

 It was not procured in the clay, but imbedded in a layer of sand, 

 which the clay had enclosed in its deposit. 



[The remainder of Serjeant Dean's collection was presented early 

 in the following year, reaching its destination in May last. The follow- 

 ing is his description of its contents :] 



17 pieces, No. 1. Teeth and fragments of bones of camels. 



27 , No. 2. Ditto and ditto of ditto of bullocks and buffaloes. 



11 , No. 3. Portions of bones of elephants. 



10 , No. 4. Ditto of teeth of ditto and piece of tusk of 



hippopotamus, (now recognized to be such.) 



5 pieces, No. 5. Portion of tufa formation, occupying the place 

 of the marrow in the tusk of an elephant. These pieces are all that 

 remain of a very large tusk taken out of the river at Adhde, from 

 beneath a plate of kankar : the bony part of the tusk was fossilized, 

 but not petrified, and from its appearance, the sepoys engaged in the 

 work during the absence of the European non-commissioned officer, 

 broke it up to try the experiment of its making pipe-clay or whiting 

 for their belts, and on burning it, succeeded beyond their expectations. 

 It is now too late to regret this great loss, but I imagine it must 

 have been a great curiosity, as it is described to have been at least 

 eight inches in diameter. 



4 pieces, No. 6, (fig. 16.) Portions of what I am told is the sting 

 of the sting-ray petrified ; also a perfect sting (fresh) ; and the jaw of 

 a water rat, (fig. 15.) 



29 pieces, No. 7. Teeth of deer of various species. 



9 , No. 8. Portions of antlers of ditto and other remains 



of ditto. 



16 pieces, No. 9. Pieces of human bones. 



5 , No. 10. Broken jaws of alligators. 



5 , No. 1 1 . Teeth of garial. 



21 , No. 12. Portions of the shell, &c. of the kachwa, or 



mud tortoise. 



3 pieces, No. 13. Pieces of teeth of hippopotamus. 



2 , No. 14. Portion of jaw and teeth of goat or deer. 



16 , No. 15. Petrified wood. 



5 , No. 16. Specimens of pipe kankar. 



2 , No. 17. Petrified perfect fish and shells. 



I consider this fossil fish to be the greatest curiosity ever found 

 in the Jamna. (See note.) 



3 pieces, No. 18. Ribs, unknown.
