Both the theoretical and experimental phases of the subject are here presented making the work elementary enough for the use of students of a junior grade in technical and engineering schools.

Slosson, Margaret. How ferns grow. **$3. Holt.

Following a chapter in the “Development of the fern leaf” the author treats of eighteen individual fern species, and devotes a double-page illustration to each. The papers deal chiefly with the subject of cell-growth and kindred phenomena. “They scarcely touch upon the development of the form and venation of the leaf in each species, and in its individual aspects only, without reference to its relation to such development in other fern species.”


“We may confidently recommend the book to fern students.”

“Miss Slosson has conscientiously followed her subject, and some of her discoveries no doubt throw light upon the phytology of the group.”
