Prokkssok Wrkmit's Book a Service to Science.

If Prof. Wright has made a mistake in the presentation of the 
case of paleolithic man, it is his misfortune rather than his fault. 
Not admitting that he has made any mistake we have still to ad- 
mit that the evidence of pahi^olithic man in America has not been 
all first-class either in quality or in (piantity, and that at about the 
same date as the appearance of his book Mr. Holmes and others 
were assiduoush' studying the question and revising much of the 
old data, subjecting them to such a scrutiny as the importance of 
the question demanded. Mr. Holmes seems to have demonstrated 
the inadequacy of much of the evidence that was relied on, but 
this was not known at the time Prof. Wright was writing, and he 
is not to blame for depending on such evidence as he had avail- 
able. The book is designed to present the evidence as it stood, 
and I do not know that any one in his circumstances, writing at 
that time, would have come to anj' other conclusion. If that ev- 
idence finally shall be all rejected it will be a service to science that 
it was allowed its full value in such a summary; if it be sustained 
it will be a striking instance of Prof. Wright's sagacit\- and dis- 
crimination. Prof. Wright is a well known glacial geologist and 
has exercised the privilege which every American citizen has, of 
using published records, discussing them, and combining them to 
reach such conclusions as he may feel warranted to publish, and 
for that he should not be held to personal account.

With the identification of terminal moraines of the great ice- 
sheet in New Knglaud it is possible for us cast-iron geologists both 
to study i)henomciia analogous to those known from the west, and 
to observe their connection with marine deposits. So far as 
known it has seemed to me that the New England phenomena do
