(Trilobites) , and botany, his work procured him a wide-spread 

 and excellent reputation. 



JOHN WARREN. 



It may not be amiss to mention here an old Englishman named 

 John Warren, who for many years dealt in shells and curiosities 

 in Boston. About 1857 he was still extant. I have little per 

 sonal information about, him, but remember him as a stout, florid 

 old gentleman, who supplied Miss Sarah Pratt and other Boston 

 amateurs with handsome shells at high prices. In 1834 he pub 

 lished a small quarto edition of Lamarck's genera of shells, 

 illustrated with 17 plates, which he entitled " The Conchologist." 



He did no original work, but, singularly enough, in Carus and 

 Englemann's Bibliography, he is confounded with Dr. J. C. 

 Warren, the distinguished surgeon of Boston, who published 

 some papers on molluscan anatomy. 



SAMUEL GEORGE MORTON. 



Among those who have promoted the study of mollusca from 

 the paleontological side, one of the earliest and most distinguished 

 names is that of Samuel George Morton.* Born in Philadelphia 

 Jan. 26, 1799, of Irish ancestry and of a family in which the 

 gifts of education were highly prized and abundantly enjoyed, he 

 early lost his father, and at the age of sixteen entered a counting- 

 room to be prepared fora mercantile career. His desire for study 

 monopolized his leisure, and in 1817 he entered the medical 

 school of the University of Pennsylvania, where he graduated in 

 1820 with honors, and afterwards pursued his studies at Paris 

 and in Edinburgh. In 1826 he returned to Philadelphia, where 

 he practiced his profession and pursued his scientific studies, and 

 the following year he married Rebecca Pearsall. His career was 

 terminated on the i5th of May, 1851, by an attack of pneumonia,
