under part of the javr the crystals are about half an inch in diameter. This 

 jaw and tooth is whiter and better preserved than any specimen we have. 

 Mr. Taber has kindly photographed the jaw for us, half the natural size, and 

 presents one to the Academy and one to accompany my report, Mr, Harford 

 is going to have a mo«ld made of the jaw, so as to obtain a cast for our col- 

 lection and for other parties. 



I give this short statement of the manner in which we have obtained this 

 specimen in order to identify it as the jaw found in the State Prison quarry.

New Discovery of Fossil Bird Tracks at the State Prison 

 Quarry, Carson, Nev. 



In the last week in August Miss Kate Garrard wrote to inform me that 

 since I left, some more bird tracks had been found on the west side of the 

 Prison yard. I wrote and requested Maj. Garrard to let my assistant take 

 the impression of them on canvas, as we had taken the other tracks. Maj. 

 Garrard complied with my request, and now presents to the Academy 17 

 yards of canvas containing 79 foot-prints of four-toed birds 



The middle toe measures five inches, the hind toe nearly two inches, the 

 spread of foot nine inches, and the step from 21 to 23 inches.
