Primary microscopy and biology. A text book for the use of students in high schools, normal schools and academies
A textbook of microscopy and biology written by Albert Schneider and printed in 1890 at Fairbury, Illinois, for pupils in high schools, normal schools and academies. The plates are plain line diagrams of optics: rays traced through biconvex lenses, prisms and curved mirrors, refraction within a water sphere, all labelled with italic letters and dashed construction lines on cream paper.
