Zoology. 647 
We regret that the author did not abandon the term frond, which 
our present knowledge of the comparative anatomy of plants ought 
to soon render obsolete. Frond and stipe ought not to be tolerated 
longer ; we should say leaf and petiole ; for a “ frond” is only a leaf 
and a“ stipe” is only a petiole. 
In the chapter on “The Fern’s Place in Nature,” the author 
adopts the term Spermaphyta for the flowering plants, and gives an 
excellent list of systematic works for the different classes of the 
vegetable kingdom.— Charles E. Bessey.
