eAvingnot look'd upon my Barometer a long time, I did 
by meer chance caft my Eye on it upon Munday laft. Be- 
cem, 13,1659. about one of the Clock p. m, 5 and juft theni 
faw the Qyicklilver higher , than I dare pofitively affirme that 
it was ever fince I had it in my cuftody^ viz, fince M^i 28, 
1554, It was compleatly and apparently above half an inch 
more than thirty inches high. I called younger men to exam- 
ine it over and over very carefully 3 by a meafure , taken ex- 
adly from the ftandard- foot of London ^ both in Brafs and in Box. 
They meafuredit often from that timCjwhich was Munday, and 
late in the night of that day 5 then on Tuefday moining early ^ 
oft-times in the day , and late at Night: alfo feme part of Wed- 
nefday. In all which time , when it was loweft , it was { as I 
faid at firft) compleatly 30 i inches-, fometimes manifeflly high- 
er to the eigth or tenth part of a inch. 
For this Barofcope I have two Glafs-canes in one vcflel of 
ftagnant Quickfilver. Theyareofequallength, not fully two 
inches higher, than the Mercury afcendedj and no Bolt-head 
to either of the Clafles. i he one hath not been moved thefe 
two or three years, and hath a tindlure of the Mercury on the 
empty top,as from the fleams of the Mercury in fome hot Sum- 
mer > the other Glafs was placed there about" a year and an half 
agoe. This hath no tindture on the top. BoeIi agreed in this 
Indication , as others aiBrme 5 but, to my Eye, in the latter 
Glafs the Qaickfilver feemed to be fomething higher.- 
.The Weather was at firft difcovery very bright and clear; a 
'gentle froft , by the Suns heat melting. The Air wa: very fi- 
lent 5 no wind ftirring , and the curious Wind-vaae noting, that 
the wind was diredly in the Ea^ all the firft day ( Decemb. 1 3 O
