Every one ffiiuiliar witli P^uropean anthropology will de- 
mand a longer era than 10,000 years, counting back from the 
present da^", for the existence of neolithic man on that conti- 
jient. But when we reflect that neolithic culture was almost 
certainly introduced into America from Eiirope and must 
therefore be younger here than there we may possibly be sat- 
istied with that amount of time For the American neolithic 
dynasty. 
1 may add that it is at present I'ar from certain that i)aUe- 
olithic man ever reached this continent at all though the 
doubt rests at present on merely negative evidence. 
3. It will of course be urged that this conclusion which 
seems legitimately deducible from the narrative here given, 
if accepted, rests at bottom on the testimony of one man. In 
a measure this is true though I have taken occasion to point 
out how strongly circumstantial evidence supports this testi- 
mony in a way that seems to render scepticism quite unreas- 
onable. Beyond that the only reply that can be made is that 
almost all similar cases must in like manner rest on the testi- 
mony of some one individual. The way in which specimens 
occur precludes the possibility in most cases of securing any 
other testimony and even if it should be the good fortune of 
a geologist to come on such a relic himself the rest of the 
world, if it accepts the "find" at all, must accept it on his 
testimony alone. It is in the highest degree improbable that 
such relics will ever be discovered and disinterred in the 
ijresence of the geological and anthropological societies of 
the country. B}^ cumulative evidence derived from the multi- 
plication of carefully investigated cases must the (luestion of 
man's antiquity in North America be answered. 
REVIEW OF RECENT GEOLOGICAL 
LITERATURE. 
Text-Book of Palceoiitology. By Karl A. von Zittel Tiunslated 
and edited by Charles R. Eastman Ph. D.. Vol. i, Part 1, with 593 
wood cuts, pp. 352. A mere translation, from German into English, of 
the great text-book of professor Zittel would have been no small task: 
and such a work would at any time have met a hearty welcome at the 
hands of American students of paheontology. Dr. Eastman, however, 
has undertaken more than a translation. With the consent and co-op-
