Mr. Lea, in referring to the death of Augustus E. Jessup, one of our old 

 members, mentioned that the deceased was elected in 1818, and that 

 he had been an ardent student of mineralogy and a most persevering 

 collector, being in the habit of visiting on foot and collecting largely from dis- 

 tant localities. In 1819 he accompanied Major Long's expedition to the Rocky 

 Mountains as mineralogist and geologist, and handed in his report to the Depart- 

 ment, but for some reason, unknown at present, it was not#inserted in the 

 Journal of that Expedition as published. Having entered into an active busi- 

 ness career, in which he was eminently successful, he retired in the year 

 1853 with an ample fortune, having made many friends by his probity, punc- 

 tuality and liberality. He was frank and open in his manners, prompt and 

 just in his dealings and liberal in his views. While immersed in the cares of 

 a large business, he did not forget his early attachment to the Academy. He 

 was unable, from his residence being at some distance, to attend the meetings, 

 but he watched with pleasure the growth and usefulness of our institution, 

 and was always ready to contribute liberally to promote the objects of Natural 

 History. He died suddenly, on the 17th day of December, 1859, at his resi- 

 dence in Wilmington, Del., in his 63d year. 



In conclusion Mr. Lea offered the following resolutions :

 have lost an old, esteemed and valued associate, who, through a long and sue-
