I went to the University of Maryland's McKeldin Library this afternoon to photograph a figure in a paper by Charles Darwin published in Nature in 1878*. I need the figure for a manuscript about Darwin's work with mollusks. Although Darwin's paper is available on The Complete Work of Charles Darwin Online, I wasn't satisfied with the quality of the figure extracted from the pdf version. So I decided to photograph the figure directly.
Luckily, the U of MD has a complete collection of Nature, although the 19th century volumes are not in the best state of preservation.
According to the stamp on the fist page, volume 18 once belonged to an O. V. Riley of Washington, D.C.
Here is the 2nd page of Darwin's paper and the figure I needed. Darwin was actually relaying a letter sent to him by a correspondent from Massachusetts.
