slightly altered by it until after the addition of an acid; from which 1 
infer that a portion of the sulphuretted hydrogen is in a state of combi- 
nation with some basis. 
The situation of the village of Avon in one of the most beautiful 
and fertile portions of western New- York, and the valuable medicinal 
qualities of its springs, conspire to render this one of the most attrac- 
tive watering places in the State. 
JViagara Springs, — The county of Niagara is no less abundantly sup- 
plied with sulphur springs than those which have been already noticed. 
One of these occurs in the town of Pendleton near the canal, others are 
found in the neighborhood of Lockport and near the Falls of Niagara; 
but neither of these have, I believe, been hitherto particularly examined. 
In the museum of the Albany Institute, is a bottle of water from a 
spring on Grand Island presented by the late highly esteemed Surveyor- 
General, Simeon De Witt, labelled " Sulphuric acid." On testing this 
water I found it to redden litmus paper, and to give a dense white pre- 
cipitate with muriate of barytes. The specific gravity is 1.00254. 
The amount of saline matter which it contains is, therefore, exceedingly 
small. 
Springs of Erie county. — About four miles from Buffalo, upon the 
Indian lands, is the Seneca spring, long known by the name of the 
Deer Lick. There are several of these springs, issuing from the oppo- 
site sides of the stream upon which they are situated, and a large quan- 
tities of sulphuretted hydrogen gas is continually evolved from them. 
According to Prof. Charles U. Shepard, the water of the Seneca spring 
js strongly sulphureous, but is free from uncombined carbonic acid; and 
contains notable quanities of the carbonates of lime, magnesia and soda, 
together with the sulphate of lime.* 
Sulphur Springs of Chautauque county, — In the county of Chautau- 
que, sulphur springs are of frequent occurrence, and apparently have 
some connexion with the issues of carburetted hydrogen gas, for which 
that county has become so celebrated. In the village of Fredonia, 
many springs of this kind have been discovered, but they are said to 
lose their sulphureous character in a short time. This, however, is not 
the case with those found elsewhere. On the shore of Lake Erie, about 
a mile east of Van Buren harbor, a spring highly charged with sulphu- 
retted hydrogen issues out of the slate rock, nearly on a level with the
