Firjl, I obferve upon the Barometrical Tables of 
tliefe two Years, that they confirm former Remarks 
made by Dr. c Derham and others, of the Confent of 
the Barometers in Places at a good Diftance from 
each other. Not only the monthly mean Heights 
agree in the three Diaries of thefe two Years here in 
England , but alfo the greateft Afcent and Defcent of 
the Mercury happen commonly on the fame Day, and 
the Barometers have been found to agree in their Mo- 
tions to an Hour, fo far afunder as Townly in Lanca - 
Jhire , and Greenwich nzzr London, which is near i6q 
Miles, although that might be partly accidental. The 
Barometer at Crane-Court and Soutbwick , diftant 
about yy Miles, being compared, feem very feldom 
to vary from their mean Difference above ~ and i 
each way > at Soutbwick and Kent fomething more. 
From whence it might be expetted, that the Weather 
fhould be much the fame in all thefe Places ; which 
nevertheless feerns not to agree with Accounts in fome 
Years from different Parts in this Ifland, not very 
far diftant: And I myfeif have obferved fometimes 
Clouds to lie in one Part of the Horizon for a great , 
Part of a Day, which have difcharg'd a large Quantity 
of Rain in Places not far off, while the Place, where 
I have been, has all the while enjoy'd fair Weather, 
and vie e verfa. Whence it appears, that the Baro- 
metrical Alterations of the Air extend farther than 
their Effe&s, as to the Produ&ion of Rain, at thofe 
times. Comparing the Diaries of Crane-Court and 
Upjali I find the Barometers vary from their mean 
Difference an Inch and half each way i Crane-Court 
and Tadua as much, or more, and often go a pace 
quite contrary ways at the fame time, and their 
monthly
