EDWARD D. COPE. 

 Natural science and • philosophy have 

 sustained a heavy loss in the premature 

 death of Professor Edward D. Cope. His 

 work began at a most favorable time, in 

 1859, when comparative anatomy first felt 

 the impetus of the ' Origin of Species,' and 

 for thirty-eight years his active mind has 

 been hastening our progress in no less than 

 five great lines of research. In each his 

 inspiring example and leadership will be 

 sadly missed. He passed away upon April 

 12th, at the age of fifty-seven,in the full vigor 

 of his intellectual powers, leaving a large 

 part of his work incomplete. Almost at 

 the last he contributed several reviews to 

 the Naturalist, and upon the Tuesday pre- 

 ceding his death he sent to the press an 

 elaborate outline of his University lectures 

 containing his latest ideas of the classifica- 

 tion of the Vertebrata. For two months his 

 health had been affected by a serious dis- 

 order, which might possibly have been 

 remedied by a surgical operation. This 

 was unfortunately postponed until it was 

 too late, and the end came so suddenly that 

 his family decided not to remove him from 

 his house, in Pine Street, which was both 

 his study and museum. He thus passed 

 away in the scene of his life work, surround- 

 ed by his fossils and books. A gathering of 

 his scientific friends in his memory also took 

 place here a few days later. His will proves 

 to be consistent with his life, as he leaves
