Mr. W. S. Sullivant. — We regret to learn from the " Journal 

 of Botany" of the death of this eminent American botanist, which 

 took place on the 30th April, at Columbus, Ohio, at the advanced 

 age of 70 years. He was the author of several memoirs on the 

 bryology of the United States, of numerous sets of actual speci- 

 mens of American mosses, and of the " Icones Muscorum." His 

 extensive bryological herbarium and library have, we understand, 

 been left to the Herbarium of the Harvard University.
