euettySve in thifes “yee: The siaibect range at eg for 
five years is 2.138 ; at New Yorl in seven years, 2.25. If the 
range of the barometer were proportioned to its ee ier 
this would give for Hudson 2.163. At Boston, during a period 
of twelve years, the range of the barometer is stated at 2.50. It 
may then be naturally inferred, that for considerable elevations, 
the range of the barometer diminishes n more rerids than: atic | 
lute height.
