398 PIONEERS OF SCIENCE IN AMERICA. 



hundred species, many of them recently gathered in California 

 by Dr. Bolander, was issued in 1865. The sets were disposed 

 of with the same unequalled liberality as before displayed. 

 Still later, Mr. Sullivant aided his friend Mr. Austin both in 

 the study of his material and in the publication of his Musci 

 Appalachiani. 



In his Musci Cubenses, which appeared in 1861, Mr. Sulli- 

 vant named the species of Charles Wright's earlier acquisitions 

 in Cuba and described the new ones. These mosses were also 

 distributed in sets by the collector. His researches upon later 

 and more extensive collections by Mr. Wright, in which many 

 new species were indicated, were left in the form of notes 

 and pencil sketches at his death. The same is true of an 

 earlier collection, made by Fendler in Venezuela. 



Mr. Sullivant was several times called upon to work up the 

 mosses gathered by Government exploring expeditions. Thus 

 the Bryology of Rodgers' United States North Pacific Explor- 

 ing Expedition was early prepared for publication by him in 

 the most elaborate manner. But, from causes over which he 

 had no control, it has never been published, although brief 

 characters of the principal new species have seen the light. 

 The fact that Sullivant's exquisite drawings of these species 

 were not promptly engraved and given to the scientific world 

 is especially to be regretted. 



In the case of the South Pacific Exploring Expedition, 

 under Commodore Wilkes, the volume on the mosses was not 

 published in his lifetime, but Mr. Sullivant issued a separate 

 edition of his portion of it in 1859. It forms a sumptuous 

 imperial folio, the letterpress having been made up into large 

 pages, and printed on paper matching that used for the twenty- 

 six plates. The fourth volume of the Pacific Railroad Reports 

 contains Sullivant's descriptions of the mosses collected in 

 Whipple's Exploration, occupying about a dozen pages, and 

 accompanied by ten admirable plates of new species. 



The Icones Muscorum, however, is Mr. Sullivant's crowning 

 work. It was issued in 1864, and consists of " Figures and 

 Descriptions of most of those Mosses peculiar to Eastern 

 North America which have not been heretofore figured," form- 

 ing an imperial octavo volume with one hundred and twenty- 

 nine copperplates. "The letterpress and the plates," says 

 Prof. Gray, u (upon which last alone several thousand dollars
