after critical determination were divided into fifty sets, each of 
about 360 species or varieties, with printed tickets, title, index, 
ete., and all except a few copies for gratuitous distribution were 
generously made over, to be sold at less than cost, for his 
esteemed associate's benefit, and still more that of the botanists 
and institutions who could thus acquire them. The title of this 
classical work and collection is Musci Boreali Americani quorum 
specimina easiccata ediderunt W. S. Sullivant et L. Lesquereux ; 
1856. Naturally enough, the edition was immediately taken up. 
Tn 1865 it was followed bv a new one, or rather a new work, | 
of between five and six hundred numbers, many of them Cali- 
fornian species, the first fruits of Dr. Bolander’s researches in 
that country. The sets of this unequalled collection were dis- 
posed of with the same unequalled iberality, and with the sole 
view of advancing the knowledge of his favorite science. This 
second edition being exhausted, he recently and in the same 
spirit aided his friend Mr. Austin, both in the study and in the 
publication of his extensive Musei Appalachiant. 
To complete here the account of Mr. Sullivant’s bryological 
labors illustrated by “ exsiccati,” we may mention his “ Musci 
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 researches upon later and more 
extensive collections by Mr. Wright remain in the form of notes 
and pencil sketches, in which many new s ecies are indicated. 
The same may be said of an earlier, still unpublished collection, 
made by Fendler in Venezuela. Another collection, of grea 
vo elaborately prepared 
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 en- 
graved 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 Government, 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 paper 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
