The third or Lower Avon Spring is similar in its composition to the preceding. It is re- 

 markable for the large volume of water which it discharges. This has been estimated to be 

 equal to fifty-four gallons in a minute, and I apprehend that this is not far from being correct. 



The waters of all the Avon springs give out powerfully the odour of sulphuretted hydrogen, 

 and have a strong saline taste. They speedily blacken silver and the salts of lead. The 

 solution of arsenious acid is but slightly altered by it, until after the addition of an acid ; from 

 which I infer that a portion of the sulphuretted hydrogen is in a state of combination with 

 some basis. 



The situation of the village of Avon in one of the most beautiful and fertile portions ot 

 Western New- York, and the valuable medicinal qualities of its springs, conspire to render 

 this one. of the most attractive watering places in this State. 



Genesee County. In this county, wjp have, near North-Byron, a sulphureous spring, 

 the gas of which is so copiously given out as to be inflamed ; and in the,, southeast part of the 

 same town, are springs of a similar kind. 



A very remarkable locality in this vicinity deserves to be particularly noticed here, as the 

 occurrence is undoubtedly to be referred to the same general agencies which are concerned in 

 the production of sulphuretted hydrogen. I refer to the Sour Spring, so called, vvhich exists 

 in the southwest corner of the town of Byron. The acid is produced from a hillock about 

 two hundred and thirty feet long and one hundred feet broad, elevated four or five feet above 

 the surrounding plane. According to Prof. Eaton, the strength of the acid increases in a 

 drought. He states, that .when he examined the locality, considerable rain had recently fallen, 

 and the acid in most places was very dilute, but in soine it appeared to be perfectly concen- 

 trated, and nearly dry in its combination with the charred vegetable coat.. In this state it was 

 diffused throughout the whole hillock, which was every where covered With charred vegetable 

 matter to the depth of five to thirty or forty inches, occasioned by the action of the sulphuric 

 acid. Wherever holes were sunk in this hill, the acid accumulated, and also in the depressions 

 of the contiguous meadow grounds. .. - ' 



There is another locality of a similar kind a hundred rods west of Byron Hotel, and two 

 miles east of the former, which is remarkable in consequence of the great quantity of acid.
