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 Eed Sandstone Crocodile from the 

 Traiassic Strata of Elgin," 1 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 Eiver Connecticut, in part of its course through 

 the country which bears its name, and in the northern district of
