42 EXTINCT MONSTERS 
Hitchcock (see p. 45), and resemble more especially those 
belonging to his genus Brontozoum. Other specimens were after- 
wards found in the same locality. Professor Sollas had casts 
made of impressions of the feet or a living emu in the Clifton 
Zoological Gardens, for the sake of comparison, and found a good 
deal of agreement between the two. Nevertheless, from what we 
now know of Dinosaurs, it would be unwise to say that the 
impressions were made by birds. 
Professor W. C. Williamson has described some very interest- 
ing impressions from Cheshire. They were found, by a former 
pupil of his (Mr. J. W. Kirkham), near Weston Point. They 
are unlike those of the Cheirotherium, previously described, and 
differ from all others yet found in showing very distinctly what 
are probably the marks of scales. The form of the foot also 
differs in being more quadrate. Professor Williamson says it 
reminds him of certain footprints found by Dr. King in the 
Carboniferous rocks of Pennsylvania. The arrangement of the 
scales corresponds closely with that seen on the foot of a modern 
alligator. The impressions suggest a saurian much more than an 
amphibian. 
These impressions figured by Professor Williamson remind 
one a good deal of some tracks described by Professor Huxley, 
in his paper on a “New Red Sandstone Crocodile from the 
Traiassic Strata of Elgin,’! which may have been made by that 
ancient leviathan. 
We now pass on to give some account of those famous foot- 
prints in the Connecticut Valley, of which probably all geologists 
have heard. The River Connecticut, in part of its course through 
the country which bears its name, and in the northern district of
