withstanding that the ratio of their specific gravities is near 
the same. Still, Mr. Dalton’s theory is only an hypothesis ; 
and is not acquiesced in by all chemists of note; although it 
appears to aflord a very plausible explanation of the phenom- 
ena observed upon the mixture of gases. . 
As to the plausibility of my speculations, I wish to obtain 
the opinion of some person better qualified than myself, to

The range of mountains rises on the table land between the 
Delaware and Susquehannah rivers, and extends under va- 
rious names through the counties of Wayne, Susquehannah, 
and Luzerne, until it is lost in the highlands of the sources 
of the Lehigh. Its general course is W. of S. The Bel- 
mont mines are the most northerly yet discovered in Pennsyl- 
yania. They approach within twenty five miles of the Sus- 
quehannah river, nine miles above the Great Bend bridge.
