Analytical Keys to the Genera and Species of the Fresh Water Alga 
and the Desmidie of the United States. Alfred C. Stokes (8 
vo. pp. 116, one plate ; Portland, Conn., 1893). 
Dr. Stokes is an adept in the compiling of artificial keys, as we 
have had occasion to note in examining his publications in the 
Journal of the Trenton Natural History Society. That such keys 
are important time-saving devices must be apparent to every one, 
and when constructed with the accuracy of Dr. Stokes they become 
important factors in the rapid determination of genera and species. 
The only danger in their use lies in the fact that they cannot, as 
a rule, cover quite all the variations which some species exhibit. 
The present work is*based on the wigs of the late Dr. Francis 
Wolle. N.S.
