COOKE’S BRITISH DESMIDS. 
This work, now completed within the promised twelve months, 
is issued, bound in one volume in green cloth, gilt tops, at two 
and a half guineas. The number of species included is 370, 
which is more than double the 162 of Ralfs’ “ British Desmidie*,” 
and nearly six times as many as were included in Hassall’s “ Fresh 
Water Algas,” whilst only 60 less than the 430 of Wolle’s 
“ Desmids of the United States.” 
HENRY WILLIAM RAVENEL, LL.D. 
We regret to record the death of our old friend and corres- 
pondent, H. W. Ravenel, of Aiken, S. Carolina, who passed over 
to the great majority on July 17, 1887, at the age of seventy-three 
years. A good correspondent, an indefatigable collector, a shrewd 
observer, and a conscientious man, if not a profound scientist, he 
was an enthusiastic Botanist, amid the cares and troubles of an 
anxious life.
