by Pritzel in his Thesaurus. 1 It was not put on sale, but fifty 

 copies were distributed with a free hand among bryologists 

 and others who would appreciate it. 2 



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 J 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 Botany 

 of the Northern United States " was in preparation, Mr. Sul- 

 livant was asked to contribute to it a compendious account of 

 the Musci and Hepaticce 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 execu- 

 tion, that Schimper, then the leading bryologist of the Old 

 World, and a most competent judge, since he has published 

 hundreds of figures in his " Bryologia Europsea," not only 

 adopted the same plan in his " Synopsis of the European 

 Mosses," but also the very figures themselves (a few of which 

 were, however, originally his own), whenever they would serve 

 his purpose, as was the case with most of them. A separate 

 edition was published of this portion of the Manual, under the 

 title of " The Musci and Hepaticse of the United States east

2 A tribute is justly due to the memory of the second Mrs. (Eliza Gr. 

 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 commemorated in Hypnum Sullivantice of Schimper, a new 

 Moss of Ohio.
