them: And haWng foraetimes order'd my fervaots to take 
notice of the Difparity, and divers times carefully obferv'd iE 
my felf, when I pafs'd to and fro between Oxford and Stanton, 
I generally found, that the Oxford Barometer and the other, 
did, as it were by common confcnt^ rife and fall together fo, 
as that in the former the Mercury was ufually | higher 3 than in 
the latter. 
Which Obfervations may teach us^ that the Subterraneous 
fteams, which afcend into the Air, or the oth^r Caufes of th@ 
varying Weight of the Atmofphere^ do, many times^ and ac 
leaft in fome places, uniformly enough affed: the Air to a 
greater height, than^ till I had made this tryallj I durft con- 
clude, , 
Butj as moft of the Barometrimll obfervations are filbjed: 
to exception, fo I found the formerly mentioned to be. For 
( to omit leffer variations ) riding one Evening,from Oxford to 
Stanton, andbavingj before Ltookhdrfe, look't on the Barof^ 
$'jdpe in the former of thefe 2. places, Lwas fomewhat furprifcd, 
to find at my comming to the latter, that in places no farther 
diftant, and notwithflandingthe fhortnefsof the time (which 
was but an hour and a half, if fo much ) the Barmeter at Stan-' 
ton was fhort of its ufual diftanqe from the other , near a quarter 
of an Ineh^ though, the weather being fair and calm, there ap- - 
pear'd dothing .of manifefl change in the Air, to which I could 
adicribe fo great a Variation 3 and though alfo, iince that time^ 
iht Mercury in the twolnftruments hath, for the moft part, pro«^

And thefe being the only Obfervations, I have yet rnet with^ ,
