at the end of the windlasses, and the handspikes being removed also, arise of a few 

 inches in the water throws the whole dam open at once — a method that is usually 

 practised in the cold-weather floods, and when the rise of the water is not very 

 great. In the height of the rains, the logs of wood and rubbish borne in the waters 

 makes this out of the question ; fig. 3 being the state of the sluices at that period.

V. — Note on the Jabalpur Fossil Bones. By James Prinsep, Sec, Sfc. 



[Read at the Meeting of the Physical Class, 3rd October.] 



In consequence of a hint from Dr. Hugh Falconer, that he had 

 heard of the discovery of some fossil hones at Jabalpur, I inserted a 

 notice in the June number of the Journal, soliciting information on the 

 subject from some of my correspondents on the Nerbada. 



I am happy to say, that my appeal has not been ineffectual, and 

 that the subject has been taken up with zeal by Doctor G. G. Spils- 

 bury, Civil Surgeon at Jabalpur. That gentleman has sent me by 

 dak three specimens of the fossil bones for presentation to the So- 

 ciety, promising a further supply when the season shall enable him 

 to visit the spot, and offering to conduct any extended investiga- 

 tions which the Physical Class may point out as desirable to elucidate 

 the subject. Doctor Spilsbury informs me, that the fossil remains were 

 discovered by Captain Sleeman two years ago. They are not mentioned 

 by Capt. Franklin in his survey of that part of the country, printed in the 

 lstpt. Trans. Phys. CI. neither by Dr. Voysey, nor Captain Coulthard: 

 Captain Sleeman is therefore entitled to the sole credit of having brought 

 the interesting fact to light, and we may hope from his official situation 

 that he will zealously take measures for making a particular examina- 

 tion of the spot, so as to extract if possible some fragments of bone in 

 better preservation, and enable us to ascertain to what animals they 

 belong, and to what epoch of the world's history they may be referred. 



Dr. Spilsbury describes the locality as being about 1^ miles N. E. 

 of the residency at Jabalpur, on the northern side of a broken range of 

 limestone hills, capped with a horizontal layer of trap, rising from the 

 valley of the Nerbada, about 150 feet to the east of the small rising 

 ground, where the petrified tree was discovered, which is in the museum. 



The three specimens sent are in too mutilated a condition to enable 

 us to pronounce what they may be, but the osseous structure of the 

 two first is very apparent. 



They differ materially from the fragments of Himalayan fossil bone 

 brought down by Mr. Royle in January, inasmuch as the latter contain-
