topography, editing and sometimes necessarily re-writing their ill- 

 expressed reports, but generously giving them full credit for all 

 their work, even where much of it might have been his own. The 

 volumes of the Final Reports, more than half of them from his pen, 

 present a singularly impressive picture of the extent and value of 

 a Survey which will be classic in geological literature, and will form 

 the noblest monument to the genius of J. P. Lesley. 



He remained in Philadelphia for three years longer, until the last 

 volume of the Survey publications had been issued. Thereafter, in 

 the summer of 1S96, he removed to the village of Milton, where 

 nearly fifty years before he had been pastor, and where he had 

 recently spent his summer holidays. In that cherished retreat, so 

 full of tender associations, he spent the remaining years of his life, 

 slowly growing feebler, until on the evening of the 1st of last June 

 he passed away. 



Lesley was upwards of 6 feet high and, at least in his later

 nose and mild eyes, was marked by a strong individuality in which 

 firmness and kindliness were equally represented. He had great 

 powers of conversation, and a remarkably winning manner which 

 irresistibly attracted those who were thrown into personal contact 

 with him. I shall retain as long as memory serves me the re- 

 collection of him in the midst of his Philadelphian home, with his 

 charming wife, his two daughters, his piles of cases of maps and 

 reports, and his geological assistants chivalrously on the alert to 

 anticipate his wishes and to carry out his instructions. 1 



He had been elected a Foreign Correspondent of our Society in 

 1866, and was promoted to the rank of Foreign Member in 1887. 



AVithin the last few weeks geological science has sustained a 

 grievous loss by the death of one of its greatest masters — the 

 illustrious Karl Alfred vox Zittel. Although for several years 

 past he had not been in robust health, yet his keen and kindly 

 eyes retained still so much of their old brilliance, his interest 

 in the progress of his favourite studies continued to be so lively, 

 and the charm of his personal intercourse remained so delightfully 

 unimpaired, that his wide circle of devoted friends could not but

 the facts gathered together by Mr. B. S. Lyman in an excellent Biographical 

 Notice (with an admirable portrait), published in the 'Transactions of the
