A letter from Vr. ?<:ohQxt plot 0/ Oxford, to Dr* 
Martin Lifter F. oftheV^. ^. concerning the ufe 
which may be made of the following Hiikoxy of the. 
Weather , made by him at Oxford through out 
the year 1684. "^^ ^^-^ ' *^ ' • 
IT would be needlefs to acquaint you with the Uni- 
verfal approbation, your new and eafy invention of 
obrerving the rife and fall oltliQ Mercury in the Ba- 
ri^7;2e^^r(byparalleilines drawn from every decimal part 
of each month of its whole extent,) was received in our 
Fhilofophical Society Oxford : fi nee 1 here fend you the 
Cb/erv, of a full year made by their order,not only of the 
rife, and fall of the j^/r/^j-//t^^r,(markt by the wandring 
prickt line in the figure belonging to each month J and 
the weatherj but alfo how the wind flood each day 
throughout the whole year, except the Month of Jan. 
which was not thought of atfirft,- though ('if we refped: 
the ufe of fuch ObfervationsJ as material a part as any 
whatever : for when once we have procured fitperfons 
enough to make the fame Obfervations in many for- 
reign and remote^ parts, how the winds flood in each, 
at the fame time, we fhall then be enabled with fome 
ground's to examin, not only the coaflings, breadth,and 
bounds of the winds themfelves, but of the weather they 
bring with them ; and probably in time thereby learn, to 
be forewarned certainly, of divers emergencies (fuch as 
heats, colds, dearths,plague,and other epidemical difleni- 
pers,) which are now unaccountable to us J and by their 
caufes be inflru£ted for prevention, or remedies : thence 
too in time we may hope to be informed how far the pofi* 
tions of the planets in relation to one another,and to the 
fixtftarrs, are concerned in the alterations of the wea- 
ther,and ia bringing and preventing difeafes,or other ca- 
lamities
