THE AMERICAN NATURE SERIES

The primary object of this series is to answer questions which the contemplation of Nature is constantly arousing in the mind of the unscientific intelligent person. But a collateral object will be to give some intelligent notion of the "causes of things." The books will be under the guarantee of American experts, and generally from the American point of view. The series will be in six divisions. (Prospectus on request). The following volumes are ready:

FISHES, by David Starr Jordan, President of the Leland Stanford Junior University. 8vo. 789 pp. With 18 colored plates and 673 illustrations; $6.00 net; carriage extra.

AMERICAN INSECTS, by Vernon L. Kellogg, Professor in the Leland Stanford Junior University. 8vo. 694 pp. With 13 colored plates and many illustrations; $5.00 net; carriage extra.
