states the locality of his specimens ; and later the references are 

 grouped for each species alphabetically arranged. The bibliog- 

 raphy is thus a complete index. Besides this, paragraphs are 

 cited where questions of distinctive characters or of dates or pri- 

 ority come in. Dr. Lea's contributions to science, though mostly 

 zoological and paleontological, also embrace valuable geological 

 and mineralogical papers. The first of his papers appeared in 1818, 

 in the Journal of the Academy of Natural Sciences of Philadelphia, 

 and related to the minerals found near that city. The first paper 

 on Unios was published in 1827 ; the last on Uuios, nearly 50 

 years later, in 1874 ; and the last of his publications — mineralog- 

 ical, like the first, and treating of the Inclusions in Gems, etc., 

 from original microscopical observations, was issued in 1876. 

 This last subject is still a source of work and enjoyment with Dr. 

 Lea who, it is a pleasure to know, although now in his 94th year, 

 is still " blessed with good health, his mental and physical facul- 

 ties unimpaired." 



OBITUARY. 



John L. Campbell, Professor of Geology and Chemistry in 

 Washington and Lee University, died at Lexington, Virginia, on 

 the second of February last, in his sixty-fifth year. Professor 

 Campbell's scientific work was chiefly in the department of 

 Geology, and valuable papers by him on Virginian Geology, 

 showing careful field work, are contained in this Journal. His 

 last paper is the Review of the Geological Reports of Professor 

 Wm. B. Rogers, the closing part of which is published in the 

 present number. He entered upon his professorship at Lexington 

 in 1851. He had the affection and respect of his students, and 

 was esteemed by all who knew him for his great excellence of 

 character. He leaves several sons and daughters, and one, Pro- 

 fessor Harry Campbell is already an active geologist, and has for 

 some time been associated with his father in his geological work.
