A Biographical Notice of 

 George Henry Horn. 



BY PHILIP P. CALVERT.* 



The preparation of a biography must necessarily be influenced by 

 the attitude whicli its subject assumed tov/ard biographical notices 

 in general. A friend of Dr. Horn writes : " He told me once that 

 Professor Cope agreed with hira that the story of their lives, outside 

 the printed record of their scientific work, could be well and suffi- 

 ciently told in one hundred lines. He added that he told Cope that 

 he would like to write his (Cope's j life and he said with considerable 

 pride that Cope replied, ' Horn, I would trust you to do it.' " Horn 

 himself contributed a notice'^' of his friend and teacher, Dr. LeConte, 

 which fills five closely-printed octavo pages of small type. Those 

 who have been associated with him in this Society may therefore feel 

 justified, to a certain extent, by his own example, if the space, which 

 they deem requisite to preserve a fitting record of his life and works, 

 considerably exceeds the limits he thought necessary. 



George Henry Horn, born in Philadelphia, April 7, 1840,
