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 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 Hepatice 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 Europa,” 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 Hepatic of the United States east

? 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 commemorated in Hypnum Sullivantie of Schimper, a new 
Moss of Ohio.
