Scientific American, Vol. 27, No. 2 (1872)
This is a periodical volume, Scientific American vol. 27 no. 2 from 1872, published in New York for a general readership interested in science and invention. Its pictures are black-and-white engravings of mosquitoes and their larvae and pupae, drawn in careful detail with labelled figure numbers, showing body segments, wings and legs; a designer could take their precise hatched linework and specimen-plate layout as a model for scientific diagrams.
