confifts of two Parts: The Upper fhews the mean 
Height of the Barometer, taken in the Method pro-

out the Year, for each Place ; and in each Column the 
higheft Month is mark'd with an A, the loweft with an 
/, to make them more obfervable to the Eye f At 
the Bottom, the Mean of the whole Year is fet down 
for each Place. At the Foot of this Table is another, 
{hewing the greateft Afcent and Defcent of the Mer-
