BIOGRAPHICAL SKKTCII. 6 



accompanied by the specimens themselves of Mosses and 

 Hepaticas collected in a botanical expedition through 

 the Alleghany Mountains from Maryland to Georgia, in 

 the summer of 1843, the writer of this notice beino; his 

 companion. The specimens were not only critically de- 

 termined, but exquisitely prepared and mounted, and 

 with letter-press of great perfection ; the whole forming 

 two quarto volumes, which well deserve the encomium 

 bestowed by Pritzel in his Thesaurus.* It was not put 

 on sale, but fifty copies were distributed with a free hand 

 among bryologists and others who would appreciate it.^ 



In 1846 Mr. Sullivant communicated to the American 

 Academy the first part, and in 1849 the second part, of 

 his " Contributions to the Bryology and Hepaticology of 

 North America," which appeared, one in the third, the 

 other in the fourth volume (new series) of the Academy's 

 Memoirs, — each with five plates from the author's own 

 admirable drawings. These plates were engraved at his 

 own expense, and were generously given to the Academy. 



When the second edition of Gray's "Manual of the Bot- 

 any of the Northern United States " was in preparation, 

 Mr. Sullivant was asked to contribute to it a compen- 

 dious account of the Musci and Hepatic^ of the region ; 

 which he did, in the space of about one hundred pages, 

 generously adding, at his sole charge, eight copperplates 

 crowded with illustrations of the details of the genera, — 

 thus enhancing vastly the value of his friend's work, and 

 laying a foundation for the general study of bryology in 

 the United States, which then and thus began. 



So excellent are these illustrations, both in plan and

f A tribute is justly due to the memory of the second Mrs. (Eliza G. 

 Wheeler) Sullivant, a lady of rare accomplishments, and, not least, a zealous 

 and acute bryologist, her husband's efficient associate in all his scientific work 

 until her death, of cholera, in 1850 or 1851. Her botanical services are com- 

 memorated in Hjjpnum Sullivantice of Schimper, a new Moss of Ohio.
