1881.J Aod [Brinton. 



prepared a work on the geology of that part of this State lying between 

 the Blue mountain and South mountain, from the Delaware to the Mary- 

 land line, which was publislied May 1st, 1837. While engaged in this oc- 

 cupation he discovered the Scolithus linearis, the oldest fossil then known. 

 In 1851 he became Professor of Natural History in the University of Penn- 

 sylvania ; in 1855, in Delaware College, acting also as Professor of Geol- 

 ogy and Chemistrjr to the State Agricultural College, and subsequently 

 became Professor of Comparative Philology in the first-named institution, 

 when that chair was first established, and filled it continuously up to the 

 time of his death. 



Turning now to his record as an author, we find Professor Haldeman 

 displayed amazing activity in a variety of branches. In his earlier years 

 natural history was his passion, while in his later life linguistics and 

 archaeology occupied most of his attention. 



The first work which I can find assigned to him was "Fresh Water 

 Univalve Mollusca," published in 1840, 2 vols., 8vo, which is now out of 

 print. This book is very scarce and it is difficult to obtain a copy, the last 

 one that was sold bringing thirty dollars ; in 1842 he published "Zoologi- 

 cal Contributions;" in 1847 he issued a work on the "Genus Leptoxis, " 

 in French, while on a visit to Paris. It is part of the Illustrations Con- 

 chologiques of Dr. Chenu. In 1849 he issued his first philological work, 

 entitled "Some Points in Linguistic Ethnolog3^" dealing with English 

 languages, and from that date he became recognized in the scientific world 

 as one of the leading philologists. 



In 1850 he published a work, " Zoology of the Invertebrate Animals ;" 

 in 1851, "Elements of Latin Pronunciation ;" in 1855 he edited "Taylor's 

 Statistics of Coal;" in 1856, a work on the "Relations of the English and 

 Chinese Languages ;" in 1864 he issued a work on the game of chess under 

 the title of " Tours of a Chess Knight ;" and in 1868, the " Rhymes of the 

 Poets," under the nom de plume oi "Felix Ago;" in 1871 he issued a 

 work on "Affixes to English Words," and in 1877, his last work, entitled 

 "Outlines of Etymology," was published. 



The Professor leaves behind him a complete work on "Word Building," 

 which is designed for the use of classes in Etjmiology, and which is ready 

 for the printer; also a work on "English Prosodj\" He also leaves the 

 manuscript of "Rat and River— a Tale of the Ohio," a mock heroic poem, 

 and a poem of the same kind entitled, " Flight of the Fishes." 



In addition to these works he has contributed probably one hundred and 

 fifty papers on various scientific subjects, especially relating to Geology, 

 Conchology, Entomology, Philology, and several branches of Zoology, 

 which have been published in the Proceedings of the American Associa- 

 tion for the Advancement of Science, the American Philosophical Society, 

 American Philological Association, Academy of Natural Sciences, and 

 many other learned societies of which he was a member. This Society' is 

 now publishing in their Transactions a monograph on " Contents of a 

 Rock Retreat in Southeastern Pennsylvania," which is descriptive of the
