The Academy of Natural Sciences 19 



The first recipient of benefits from the Jessup endowment was 

 Charles Conrad Abbott, then engaged in the study of ichthyology, 

 but later recognized as an authority on the Stone Age in America 

 and as the author of graceful contributions to the literature of 

 nature study. 



Harrison Allen 14 had begun his fine work on the bats and had 

 contributed his first papers to the Proceedings for 1861. They 

 were, in common with those prepared by him in later years, 

 characterized by painstaking accuracy and remain of permanent 

 value, conscientiousness being the keynote of the author's character 

 and work. 



John L. Le Conte 15 was adding to his reputation as one of the 

 most accomplished of American naturalists by a series of papers on 

 the coleoptera. From him his friend and protege, George H. 

 Horn, 16 was drawing the inspiration that enabled him to secure a 

 distinguished position in the same department of science. 



Thomas Meehan 17 had been elected a member ten years before 

 and was contributing to the Proceedings the results of his observa- 

 tions on the physiology of plants, continued until his death in 

 1901. He was indefatigable as Conservator of the Botanical Sec- 

 tion, and gave much time and labor, even when suffering from the 

 illness which proved fatal, to the increase and care of the herb- 

 arium. He was an acute observer and graceful recorder of the 

 life histories of plants, and it is far from being to his discredit 

 that he never, as far as known, thought it worth while to describe 

 a new species. 



John Warner's communications on the mathematics of organic 

 morphology gave a novel interest to several of the meetings,
