The death of Charles Wright on the 11th of August, and 
of George W. Clinton on the 7th of September, have called forth 
an interesting account of their work in American Botany, which 
Dr. Gray, from personal acquaintance and correspondence, is so 
well able to give. The frequent and varied botanical excursions 
of Charles Wright in Texas, Arizona, and New Mexico, his con- 
nection with the Ringgold-Rogers North Pacific Exploring Ex- 
pedition, and his numerous explorations in Cuba, extending over 
a period of nine years, enabled him to make collections which are 
scattered through all the large Herbaria of the United States and 
Europe, and have provided material for publications of great 
value to North American botanists. But two of these appear in 
his own name. George W. Clinton’s botanical work, beginning 
with three years’ scientific studies as a young man, and renewed 
after an interval of thirty-two years devoted to law, resulted in 
the Clinton Herbarium for the Buffalo Society of Natural Sciences, 
and a Catalogue of the Native and Naturalized Plants of the City 
of Buffalo and its vicinity. Dr. Gray also gives a very interest- 
ing account of Edmond Boissier and Johannes August Christian 
Roeper.
