To quickly assess the difficulty of the text, read a short excerpt:
On this account many interesting structures are not pictured. As a whole, however, these delineations fairly present the more important aspects of lunar topography as seen with good telescopes. In accordance with the usage of selenographers these plates are printed in the reversed order in which they appear in a celestial telescope. The top of each is the south, the bottom the north, the right hand the east, and the left the west. This will enable the student to compare them with the maps of th...e moon. Except when necessary for the immediate purposes of this memoir, the structures depicted in the several plates are left unnamed. On many accounts this omission is to be regretted, but an extended effort to designate by name the craters, mountains, etc. , showed that to accomplish this end it would be necessary to have key maps for the greater number of these illustrations. If the student desires to determine the name of any of the more considerable features, he can readily do so by comparing the plate with any of the good maps of the moon.
