He presided at the meeting held November 12th in commemora- 

 tion of his life-long friend the late Edward D. Cope, in the rooms of 

 the American Philosophical Society. Some of those who Avere pres- 

 ent on that occasion were painfully aware that Dr. Allen was far 

 from well. Two days later, on the afternoon of Sunday, November 

 14th, he was seized with an attack of angina pectoris which resulted 

 in death. 



In 1860 he had written to his mother: " it is my ambition to be 

 known as a good physician and a good man." Those who knew Dr. 

 Allen best as a physician and a man, know with what completeness 

 of fulfilment he had lived his life. 



George Henry Horn was born in Philadelphia, April 8, 1840. 

 His preliminary education was received in the Jefferson Boys' 

 Grammar School, from which he entered the Central High School, 

 July, 1853. He took the full course and graduated with the 

 degree of Bachelor of Arts, February 11, 1858. The degree of 

 Master of Arts was conferred on him by his Alma Mater, July, 

 1863. At the time of his graduation he lived at the southwest cor- 

 ner of 4th and Poplar Streets, where his father was the proprietor of 

 a drug store. 



Almost immediately after leaving the High School he matricula- 

 ted in the Medical Department of the University of Pennsylvania. 

 He took his degree in medicine in 1861, his thesis being entitled 

 " Sprains." 



While yet a student of medicine he contributed his first papers to 

 the Proceedings of the Academy. He did not immediately devote 

 himself to the specialty in which he later became so distinguished, 

 his first three contributions to science being descriptions of new 

 species of recent and fossil corals and comments on Milne-Ed- 

 wards' classification of those organisms. 



There is every reason to believe that his incentive to the study of 

 natural history was received, as in Dr. Allen's case, from the profes- 

 sors of the High School. In addition to McMurtie's lectures, Dr. 

 B. Howard Rand, at that time Recording Secretary of the Acad- 

 emy, was liberal in the distribution of tickets of admission to the 

 Museum, and many of his pupils found profitable occupation for 

 their Friday afternoons in visiting the collections.
