In this description we have not attempted to 
point out all the objects worthy of interest on both 
sides of this curious slab. Every part of it is full 
of interest, and presents a field for protracted obser- 
vations. The surface represented in the plate may, 
by the aid of a magnifier, be studied without the 
presence of the stone itself; for the photographic art 
displays the most minute objects without alteration 
or omission.
