ANGELO HEILPKIN. 



Professor Angelo Heilprin, the well-known naturalist died in New 

 York City, July 17. He was born in Hungary, March 31, 1853, 

 and came to the United States in 1856. He was Professor of In- 

 vertebrate Paleontology and Geology, (1880-1900), and Curator, 

 from 1883 to 1892 of the Academy of Natural Sciences, and Pro- 

 fessor of Geology at the Wagner Free Institute of Science 1885-90. 

 For several years past he held the Lectureship on Physical Geo- 

 graphy at Yale University. 



While most of the works of Prof. Heilprin pertained to geology 

 and physical geography, there are a number which are of special 

 interest to conchologists. " Animal Life of the Seashore," and the 

 " Bermuda Islands " : a contribution to the physical history and 

 zoology, both treat extensively of the mollusca. " Explorations on 

 the West Coast of Florida" (Trans. Wagner Free Inst. Sci. Vol. 

 I). On this expedition the richly fossiliferous pliocene of the Caloo- 

 sahatchie was discovered and many of the interesting species of 

 mollusks described, together with a number of those from the 

 "silex-bearing marl" of Tampa Bay, now classed as Oligocene. 

 Professor Heilprin has also published numerous papers in the Pro- 

 ceedings of the Academy of Natural Sciences. His later works deal 

 principally with volcanic phenomena, especially Mont Pele"e, where 

 he was one of the first scientific observers on the ground. 



Professor Heilprin possessed to an unusual degree the ability to 

 interest non-scientific people in scientific matters ; and to the inspira- 

 tion of his personal teaching many owe the beginnings of a deep 

 interest in geology, geography and other natural history studies. 

 Personally, Professor Heilprin was infectiously optimistic and confi- 

 dent. He successfully organized and led numerous scientific expe- 

 ditions ; and his death was due to the effects of a tropical fever, con- 

 tracted on an expedition to the Orinoco river, about a year ago.
