WILLIAM STARLING SULLIVANT. 373 



of the Mississippi River" (New York, 1856, imperial 8vo), 

 upon thick paper, and with proof-impressions directly from 

 the copperplates. This exquisite volume was placed on sale 

 at far less than its cost, and copies are now of great rarity 

 and value. It was with regret that the author of the Manual 

 omitted this Cryptogamic portion from the ensuing editions, 

 and only with the understanding that a separate " Species 

 Muscorum," or Manual for the Mosses of the whole United 

 States, should replace it. This most needful work Mr. Sulli- 

 vant was just about to prepare for the press. 



About the same time that Mr. Sullivant thus gave to 

 American students a text-book for our Mosses, he provided 

 an unequaled series of named specimens for illustrating them. 

 The ample stores which he had collected or acquired, supple- 

 mented by those collected by M. Lesquereux (who was asso- 

 ciated with him from the year 1848) in a journey through the 

 mountainous parts of the southern States under his auspices, 

 after critical determination were divided into fifty sets, each 

 of about three hundred and sixty species or varieties, with 

 printed tickets, title, index, etc., 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 for that of the botanists and institutions who could 

 thus acquire them. The title of this classical work and col- 

 lection is " Musci Boreali Americani quorum specimina ex r 

 siccati ediderunt W. S. Sullivant 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 Cali- 

 fornian species, the first-fruits of Dr. Bolander's researches 

 in that country. The sets of this unequaled collection were 

 disposed of with the same unequaled liberality, 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 "Musci Appalachians " 



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

 labors illustrated by "exsiccati," we may mention his "Musci
