We commend this collection of the Algae of the United 
States to our readers. The specimens are carefully determined by 
gentlemen thoroughly competent for the work, and although there 
are numerous collections of fungi, some good, and some indifferent, 
constantly in course of issue, it is but rarely that collections of 
Algae make their appearance. We do not hesitate to pronounce 
in favour of the excellent quality of the above series now in course 
of publication.
