Trans. N. Y. Ac. Sci. 12 Oct. 22, 
cality, in company with his son and Dr. ABBOTT, had been exceedingly 
interesting, including the examination of the exact points of occurrence 
of the worked flints at different depths of the gravel-bank, as well as 
of modern Indian implements at many points over the surface, but 
never imbedded in the gravel. He expressed his own very clear and 
decided impressions as to the care and fulness of Dr. ABBOTT’S re- 
searches, and the substantial accuracy of his results. 
In reply to an inquiry of Mrs. E. A. SMITH, Dr. MARTIN further 
stated that the objections of Prof. BoyD DAWKINS related to the origi- 
nal and incorrect views of Dr. ABBOTT, who had been misled by Prof. 
G. H. COoK’s estimate of the geological age of this gravel deposit. Dr, 
ABBOTT also believed he had made an important discovery in a speci- 
men of human tooth, which he had struck with his cane out of a gravel 
bank, and whose rolled, water-worn condition indicated a vastly greater 
age. 
The PRESIDENT stated that Prof. DAWKINS had never visited the 
locality, and had not expressed to himself any positive opinion. It 
was an interesting fact that, in DAWKINS’ classification of the early 
races of men, he calls the first race the River Gravel Men, afterward 
followed by the Cave-dwellers. 
October 22, 1883. 
The President, Dr. J. S. NEwBERRY, in the Chair. 
Twenty-nine persons present. 
The Chairman of the Publication Committee, Prof. D. S. MarTIN, 
reported that number 13, with the Index and Contents of Vol. IL., 
of the Annals, was now ready for issue. 
Mr. G. F. KuNz exhibited a supposed emerald from Gibsonville, 
Guilford County, N. C. Mr. Smith, a farmer, while ploughing on his 
farm in March last, turned up an irregular shaped, smooth-faced stone, 
the size of a hen’s egg. It glittered in the sunlight. Mr. Smith took 
the stone to Greensboro, where a jeweller pronounced it a genuine 
emerald weighing nine ounces. The jeweller was also of the opinion 
that smaller brilliants clinging to the central stone were diamonds. 
The fact was published and aroused the greatest interest among 
jewellers and mineralogists. A diamond miner visited Mr. Smith and 
offered him $1,000 for the gem. Mr. Smith refused the offer, being 
assured that the emerald was the second largest in the world and of 
immense value. He brought it on to New York and intrusted it to a 
banker, by whom it was ultimately submitted to Mr. KUNZ for exami- 
nation. After subjecting the stone to various tests, he found it tobea 
crystal of quartz, penetrated by long, hair-like crystals of green acti-
