The number of springs belonging to the class which 1 am now con- 
sidering, seems to increase as we proceed westwardly, so that it is 
scarcely possible in a report like the present, to do more than to notice 
briefly some of the most important of them. 
Cayuga Sul'phur Springs. — In the county of Cayuga are several sul- 
phurretted springs. One of these is in the town of Sennett, two miles 
north of the village of Auburn. Another, which has also acquired some 
reputation, is situated about four miles west of Auburn, on the farm of 
Mr. Nelson Van Ness. It is called West- Auburn spring. One pint 
of the water according to the analysis of Dr. Chilton of this city, con- 
tains the following matter, viz: 
Sulphate of lime, 15 . 00 grains. 
Sulphate of magnesium, 3.20 " 
Chloride of magnesium, . . , 0.25 " 
Chloride of sodium, 0.75 " 
19.20 " 
Sulphuretted hydrogen gas, 1 . 5 cubic inches. 
At Spring Mills on the eastern shore of Cayuga lake a sulphuretted 
water is said to issue from the earth in quantities sufficient for turning 
a grist mill. The w^ater is perfectly limpid, and notwithstanding the 
large stream which is continually flowing, the taste and odour of sul- 
phuretted hydrogen are very strong. 
Monroe Springs. — Sulphuretted springs are found in great numbers 
in the county of Monroe. Among them may be mentioned those of 
Rochester, Mendon, Gates and Pittsford, at all of which there are bath- 
ing houses and ample accommodations for visiters. At the village of 
Ogden, in the town of the same name, one and a half mile south of 
Spencer's basin, is a spring probably more highly charged with the gas 
than any other in the county. 
In the city of Rochester, on the east bank of the Genesee, is Long- 
muir's sulphur spring, the waters of which are much employed by the 
inhabitants. It rises through a boring of two hundred feet in depth,
