therefore hope that our friends in Sedalia will clear up its doubt- 
ful affinities; and also the’range of this genus in Carboniferous 
rocks. 
Mr. W. E. HIDDEN reported the discovery, within the city, 
by Mr. William Niven, of fine green and brown tourmalines. 
The green ones are very clear, and although minute, would cut 
into gems. With them occurred fine pyrite and pyrrhotite 
crystals. 
Mr. HIpDEN stated that he had lately received fram his mines 
in Alexander County, North Carolina, a number of emeralds, 
which are clear and of fine color. From one six gems have al- 
ready been cut, of a probable value of $500. ‘These were found 
incidentally and before the regular mining for the season had 
commenced. 
Mr. GeorGE F. Kunz exhibited specimens of ruby corundum, 
from near Atlanta, Georgia. A mass of three hundred and fifty 
pounds was found on the surface of the ground. 
Also gold-bearing quartz from near Parimaribo, Dutch Guiana. 
This occurs four miles from the coast, to which it is carried by 
the natives. 
Rhodonite, from near Cummington, Mass., was shown. For- 
merly it was found in boulders, but is now found in place. 
He also exhibited phenacite, from near Stowe, Maine. It was 
found in a pocket, associated with topaz and smoky quartz, and 
also detached. This is the first discovery of this mineral in the 
United States, outside of Colorado. The crystals are lenticular, 
thin, and resemble those from Florissant, Colorado. Large 
cavities abound in the crystals, which might have contained a 
fluid. 
Mr. Kunz gave the following particulars relating to the dia- 
mond, from Georgia, exhibited April 16th. 
In April, 1887, Mr. Lewis M. Parker, a tenant on the farm 
of Daniel Light, situated three-quarters of a mile northwest of 
Marrow Station, and thirteen miles south of Atlanta, found a 
diamond on the farm. The stone afterwards came into posses- 
sion of Mr. W. W. Scott, of Atlanta, who sent it to me for ex- 
amination. It proved to be an octahedral crystal weighing 475
