Fontaine, William Morris, White, Israel C · 1880 · published by the board of commissioners for the second geological survey · 37 pictures

A geological survey report of 1880 by William Morris Fontaine and Israel C. White, published by the Pennsylvania Second Geological Survey, documenting Permian and Upper Carboniferous plant fossils from West Virginia and southwestern Pennsylvania. Its plates are sepia engravings of fern-like fronds and pinnules, drawn in detail with some specimens enlarged and labelled, giving a designer clear botanical forms for pattern, lace-like leaf structure, and vintage scientific layout.
