The seventh group contains the impressions of the feet of Saurians or
lizards. We have a specimen of quadrupedal marks, with five toes to
each foot, about an inch long, which may have been made by these
animals. The impressions are small, but very distinct. There are
lizards of the present day with five toes, about the size of these
impressions; and these may, therefore, be set down as belonging to
this order of reptiles. Like a number of the last-named specimens,
they are in red shale.
