Report of the Commissioner of Patents for the year ..
This is an annual government report from the United States Patent Office, printed in Washington in 1849 for the House of Representatives, with agricultural matter included. Its pictures are small engraved natural-history plates of insects and a root-like growth, each shown magnified and at natural size with labels for larva, weevil, caterpillar, and perfect insect. A designer might take from them the clean scientific labelling and the pairing of enlarged and life-size views.
