In conclusion, I may state that I am well aware of the want 
of positive proof for the existence of the minerals assumed in 
these rocks, but many facts seem to support such an assump- 
tion. The water given is basic water, only dried material 
having been used for analysis, and may have been contained 
in the feldspar. 
The President, Dr. J. S. NewBERRY made some remarks 
on the investigations of Dr. Schweitzer, and said he con- 
sidered them of great importance and value. 
Pror. C. A. SEELY made some remarks on Anthracite, said 
to come from New Mexico and the Western Territories. He 
was not aware that anthracite had been found in those 
localities. 
The President, Dr. NEWBERRY, said that anthracites are 
found in the far West, but they are of later geological age 
than those of Pennsylvania. ‘They are T'riassic Cretaceous, or 
Tertiary Lignites, changed by local Volcanic action, as erup- 
tions of trap. One deposit of Anthracite near Santa 
Fe, New Mexico is a Cretaceous Lignite. The Anthracite of 
Los Bronce, Sonora, is of Triassic age. The most beautiful 
of all western Anthracite is that of Queen Charlottes Island, 
off the N. W. Coast. This is a metamorphozed Lignite, 
probably Cretaceous. 
The Coals of Central America were examined years ago 
by a geologist, Dr. Evans, sent by the United States Govern- 
ment. A Report on them was published by Congress. 
They are Miocene tertiary Lignites, of medium quality. 
Mr. KE. G. SQuIER said that he had observed Coal in San 
Salvador resembling Cannel, and in Honduras, Lignite in 
considerable quantity. In Peru 14,000 feet above the sea, coal 
is found and is used for reducing the ores of the vicinity.
