Plate 10 of Shaler's book. This image (and subsequent ones) was reproduced at a larger scale than the first 9 plates which were photos (largely taken with the Lick telescope) of the entire lunar disk. The quality of the images was quite high, providing much improved data for Shaler and later selenographers to interpret.

This full resolution image of the Mare Crisium region of Plate 10 demonstrates the high quality of the photos analysed by Shaler
