and that the origin of these hard stones employed in Europe during 
the age of polished stone is as yet undecided and much to be discussed. 
Mr. Thomas Wilson described how the nephrite implements were 
used in Alaska, and how the mineral of which they had been made had 
been found by Sir George Dawson, in the form of smooth and worn 
pekbles, in the valleys of the Lewis, the Kowak, and the Yukon rivers. 
He said that Dr. Gosse was right to advise us to wait for further infor- 
mation. The elements of jadeite and nephrite were quite common. 
Why was it that these rocks should not be found in America as well as 
in Europe? - 
Mr. George F. Kunz, of New York, presented to the congress a 
votive hatchet in jadeite, beautifully sculptured, of extremely large 
dimensions, from Canada. It was his opinion that this mineral came 
from the southern part of Mexico; but the Mexicans of modern times 
had never yet discovered its origin. It might be perhaps upon the 
summit of some mountain. He continued by giving a description of 
several new minerals, similar to jadeite, which had been used in America 
for such implements, and have been identified by Professor F. W. 
Clarke as pectolite, wollastonite, pagolite, and agalmatolite. Imple- 
ments made of these minerals have been found in divers portions of 
the United States of America, and therefore there was nothing curious 
or wonderful in finding the origin of the jadeite and nephrite in that 
country. 
M. Netto presented a portrait of a woman of the tribe of Indians of _ 
Boticude, and with it gave a description of what was called the dotogue, 
which much resembles, if it was not actually, a labret; and he said 
that many American people used it in distant portions of the country. 
In this he was supported by Dr. Hamy, who presented several curious 
specimens from his:museum of ethnography, and especially those from 
the northwest coast of America. Both Dr. Hamy and M. Netto were, 
however, in doubt whether these objects would show a relationship 
between two peoples so widely separated. : 
Mr. Thomas Wilson instituted a parallel between the paleolithic 
period in the United States and that in Europe. This period has been 
manifested in the United States of America by implements found deep 
in the river gravels at three places or more at great distances from each 
other,—the Delaware, the Minimi, and the eee a the Mississippi 
Rivers. He TEUER ities and the of and associa-
