SidUvant et L. Lesquereux, 1856. Naturally enough, the edition was 

 immediately taken up. 



In 1865 it was followed by a new one, or rather a new work, of 

 between five and six hundred numbers, many of them Californian 

 species, the first fruits of Dr. Bolander's researches in that country. 

 The sets of this unequalled collection were disposed of with the same 

 unequalled liberality, and with the sole view of advancing the knowl- 

 edge of his fovorite science. This second edition being exhausted, he 

 recently and in the same spirit aided his friend Mi-. Austin, both in the 

 study and in the publication of his extensive Musci Appalachiani. 



To complete here the account of Mr. Sullivant's bryological labors 

 illustrated by " exsiccati," we may mention his 3Iusci Cubenses, named, 

 and the new species described in 1861, from Charles Wright's earlier 

 collections in Cuba, and distributed in sets by the collector. His re- 

 searches upon later and more extensive collections by Mr. Wright 

 remain in the form of notes and pencil sketches, in which many new 

 species are indicated. The same may be said of an earlier, still unpub- 

 lished collection, made by Fendler in Venezuela. Another collection, 

 of great extent and interest, which was long ago elaborately prepared 

 for publication, and illustrated by very many exquisite drawings, rests 

 in his portfolios, through delays over which Mr. Sullivant had no con- 

 trol ; namely, the Bryology of Rodgers's United States North Pacific 

 Exploring Expedition, of which Charles Wright was botanist. Brief 

 characters of the principal new species were, however, duly published 

 in this as in other departments of the botany of that expedition. It is 

 much to be regretted that the drawings which illustrate them have not 

 yet been engraved and given to the scientific world. 



This has fortunately been done in the. case of the South Pacific 

 Exploring Expedition, under Commodore Wilkes. For, although the 

 volume containing the Mosses has not even yet been issued by Govern- 

 ment, Mr. Sullivant's portion of it was published in a separate edition, 

 in the year 1859. It forms a sumptuous imperial folio, the letter-press 

 having been made up into large pages, and printed on papqr which 

 matches the plates, twenty-six in number. 



One volume of the Pacific Railroad Reports, i. e., the fourth, contains 

 a paper by Mr. Sullivant, being his account of the Mosses collected in 

 Whipple's Exploration. It consists of only a dozen pages of letter- 

 press, but is illustrated by ten admirable plates of new species. 



The Icones Muscorum, howevei', is Mr. Sullivant's crowning work. 

 It consists, as the title indicates, of " Figures and Descriptions of most 

 of those Mosses ijeculiar to Eastern North America which have not
