Edward Hitchcock. — Hitchcock. 137 
poraries. Hitchcock never hesitated to say, " I do not know,"* 
when existing theories failed to be reasonably satisfactory. 
This was especially obvious in his treatment of the celebrated 
Berkshire trains of boulders. Had he lived two years longer, 
he would have probably adopted the glacial theory, as by that 
time it had become obvious that the immensity of the glacial 
area and the ascent of the ice thousands of feet were no 
bar to its adoption ; and he would then have been the first 
to see a terminal moraine in the hillocks of cape Cod and Long 
island. 
The name of Edward Hitchcock is more thoroughly identi- 
fied with the subject of ichnology and the C-onnecticut sand- 
stone. To him belongs the honor of having proved the exist- 
ence of a large fauna of giant bipeds and quadrupeds in the 
trias of New England from their footmarks. When he first 
examined the track of the large Jirnittozninn some eighteen 
inches in length, he threw away the slab, supposing it merely an 
accidental resemblance, but very soon he discovered that the 
accidents Avere, the law in this case and the large creatures 
were very plenty. It was the description of these gigantic 
footmarks that fortified Prof. Owen, of London, in his belief 
in the existence of the Dei nor n is of New Zealand. The bib- 
liography shows how numerous and varied were the papers 
illustrating these ichnites. The footmarks gave the first 
proofs of the existence of Deinosaurs, although they received 
the name of " ornithoid lizards or batrachians." The final 
classification of Prof. Hitchcock summarized the groups as 
follows: one marsupial; seventeen pachyd;u'tylous birds; 
seventeen leptodactylous birds ; twenty-one ornithoid reptiles ; 
twenty-live reptiles and Amphibia; seventeen Batrachia; six 
Chelonia; two fish ; twenty-four insects; twenty-one inferior 
Arthropoda or larvae ; and ten Mollusca, or over one hundred 
and fifty in all. There is a fine collection of these Ichnozoa 
at Amherst, where a room one hundred by thirty feet, with 
two smaller ones, are filled by numerous slabs, exhibiting over 
20,000 distinct impressions, all gathered by Edward Hitchcock 
and named after him since his decease. A fine nuirble bust by 
Millmore adorns one of the shelves. 
*My brother adds as very characteristic of our father, that he should 
acknowledge that he made a mistake in calling the lizards and batrach- 
ians birds at the first.
