Association of American Geologists and Naturalists. 331 
Monday, May 1, 1843.—The minutes of Saturday were ac- 
cepted, and the Chair presented from the committee on publica- 
tion the completed volume of transactions, comprising the pro- 
ceedings of the Association from its organization to the present 
time, together with all the papers which have been read at former 
meetings of the Association. It was ordered that the present com- 
mittee on publication be continued for the year to come, and that 
Dr. Amos Binney be the treasurer of that committee. It was also 
Resolved, That the thanks of the Association be presented to 
the committee of publication for the very acceptable manner in 
which they have performed the laborious and responsible duty 
of publishing the first volume of the Transactions of the Asso- 
ciation. 
Resolved, 'That the thanks of the Association be presented to 
Prof. E. Hitchcock, for his very interesting address before the 
Association on Saturday evening, and a copy be requested for 
publication. 
Prof. Hitchcock read a paper on native copper found in drift 
in Massachusetts, and also on the occurrence of yttro-cerite in the 
same state. He considered the copper as having originated in the 
primary to the north ofthe place where it was found; there was 
no drift in that direction, having any other than a northern ori- 
gin; he considered this fact might have an important commercial 
bearing. 
Dr. Jackson stated he had found the yttro-cerite in Bolton, Ct. 
B. Silliman, Jr. reminded Prof. Hitchcock that copper was 
found at Bristol, Conn., in the primary, beyond but near the 
junction of the new red, and that Prof. Shepard had expressed 
the opinion in his report, that all deposits of copper in the secon- 
dary were limited in extent, and were originally derived from the 
primary. ; 
Dr. L. C. Beck stated that native copper had been found near 
Somerville, N. J., under circumstances similar to those in Massa- 
chusetts and eiginactieut: one mass in his hands weighed when 
found, one hundred and twelve pounds. 
Prof. H. D. Rogers enquired of Dr. D. Houghton if he con- 
sidered the native copper of Lake Superior, as belonging to the 
older secondary, and whether the trap and sandstone of the penin- 
sula of Michigan, were of the same geological age as the similar 
formations of New Jersey and Connecticut.
