to the summit of the second crest in the north-west, and to the summit of (k 
first crest at the southern stations; and Table XI. gives us the entire baio- 
metric range during the transit of the great wave, distinguishing the araooQiof 
rise—anterior slope — from the extent of fall — posterior slope. Fronithf* 
numbers we learn that the full but little excused the rise, and tier* ill 
regular gradation from the north-west to the south-east. A correct deKr 
mination of the barometric ranges, and the c(ui8iruction of a map oflitw* 
similar range, would go far to make us acquainted at least with the localitn 
of great barometric disturbances, and the directions in which these diaod^ 
aiices are either compensated by opposite movements or more or less ottic 
rated by the interference of different systems of waves. The results ofifa 
and former investigations appear to indicate that the principal Hue of disi' 
nation of range is from north-west to south-east, aud that the greal«tfr 
turbance results from the transits of the north-west waves.
