 in the Transactions of this Society in 18.53. An earlier notice is given in

 fossil bones discovered at Milford, Lehigh county. Pa., the first at that 

 time found in the Triassic formation of this country. 



Mr. Lea took the advantage of his opportunities to make a full collec- 

 tion of the objects of his study and investigation, and this, with the ex- 

 ception of the collection of Tertiar}'' fossils, which was presented to the 

 Academy of Natural Sciences during his life-time, he has bequeathed to 

 the National Museum at Washington, where it will be preserved for the 

 study and admiration of future naturalists.
