adorns the pavement of the City Hall. It is to be hoped that it 

 will, in the near future, be moved to Logan Square, in immediate 

 proximity to the institution which he loved so well and served 

 so loyally, and within the walls of which he accomplished much the 

 greater part of his work. 



Charles E. Smith 28 succeeded Aubrey H. Smith as a member 

 of the Council. He was immediately appointed on the Publica- 

 tion Committee. In this position he rendered most important 

 service as a judicious adviser and an extraordinarily accurate 

 proofreader, until his death, April 15, 1900, in his eightieth year. 

 His interest in the Academy was shown by the bequest of his 

 botanical collections, books, maps and letters, and one-sixth part 

 of the sum realized from the sale of his real and personal property. 

 The latter amounted to about $75,000. Philip P. Calvert was 

 placed on the Publication Committee to fill the vacancy caused by 

 the death of Mr. Smith. 



The Eev. Dr. McCook having resigned his position as one of 

 the Vice-Presidents, a minute of appreciation of the high value 

 of his services to science was placed on the records. He was suc- 

 ceeded by Arthur Erwin Brown, Sc. D. 



Out of respect to the memory of Dr. Leidy, the office of Presi- 

 dent was allowed to remain vacant until the annual election in 

 December, 1891, when General Isaac Jones Wistar was elected his 

 successor. In the meantime the By-Laws had been amended so as 

 to provide that no member should be eligible to the office of Presi- 

 dent for more than four consecutive terms. 



General Wistar was a prudent adviser and conducted the affairs 

 of the society with dignity and efficiency for the next four years. 

 In 1892, he contributed to the Proceedings an able paper on the 

 quantity, rate of consumption and probable duration of North 

 American coal and the consequence to air breathing animals of its 

 entire consumption. He died September 18, 1905. 29 



The new lecture hall was transferred by the Board of Trustees 

 of the Building Fund in February, 1892, the opening address being 

 delivered on the 22d of that month by the Rev. Dr. McCook. 



An expedition for the exploration of West Greenland under the 

 command of Lieut. R. E. Peary had been fitted out by the Academy
