Art. III. — Gases, Acids, and Salts, of recent origin and 

 now forming, on and near the Erie Canal, in the State of 

 New-York ^ also living Antediluvial Animals ; by A. Ea- 

 ton. 



[Continued from Vol. IV. page 368.] 



The subjects embraced under these heads might be inclu- 

 ded under the geological strata from which they issue, or to 

 which they are attached. But several of them are of doubt- 

 ful origin ; and in some cases their origin is hypothetical. In 

 cases of the latter kind, I prefer giving the hypothesis under 

 this general head, to referring them more definitely. 



I shall describe and consider the following cases. 



1. The Nitrogen gas, in Hoosick, near the east line of the 

 state of New-York, in Rensselaer county. 



2. The Sidphuretted Hydrogen gas, near the head of 

 Otsquago creek, ten miles south of the Erie Canal, on the 

 Mohawk ; and the same gas one mile south of Niagara Falls, 

 on the Canada side of the river ; also in combination with 

 the waters of Springport, and of Lake Sodom in Manlius. 



3. The Carhuretted Hydrogen gas, at Vernon, twenty 

 miles west of Utica; at Gasport, six miles east of Lockport, 

 on the Erie canal ; and near Canandaigua. 



4. Carbonic Acid gas, at Albany, and in Saratoga county. 



5. Sulphuric Acid, in Byron, thirty-five miles west of Gen- 

 essee river. 



6. Sulphate of Magnesia, six miles north of Troy; also at 

 Coeymans, south of Albany ; and in small quantities, at Au- 

 burn, Genessee Falls, &c. 



7. Muriate of Lime, found every where in the marly clay 

 of this district. 



8. Sulphate of Iron, near the head of Cayuga lake, in 

 Byron, and in M'Comb's mountains, easterly from Ogdens- 

 burg. 



9. Sulphate of Alumine, near the head of Cayuga lake ; 

 near New Lebanon Springs, and in M'Comb's mountains. 



10. Carbonate of Iron, in springs five miles west of Alba- 

 ny, and along the sand plains west of Hudson river, and oth- 

 er places where bog-ore is found. 



1 1 . Muriate of Soda, on the Canal line from near Rome 

 to Niagara river ; also in the salt licks. Particularly consid- 

 ering the pseudomorphous crystals in lias and saliferous 

 rocks, imitating crystals of muriate of soda.
