fhould have more nicely watched) what I have farther gather- 
ed from Reports, is to this purpofe. 
I hear, it was obferved at Blechington, above f. miles to the 
North of Oxford^ and fo along, by BoJtofHorton.Stanton-St. Johns, 
and fo towards Whately , which is about 4. miles Eaflward from 
Oxford. Not at all thefe places at the fame time, b.ut moving for- 
ward from Blechington towards Whatdy. For it was at Stanton 
about 6. of the Clock or later (as I underftand from Mr, Boyle , 
who was there at that time;) but had been at Bhchington a 
good while fooner. And I am told, that it was taken notice of 
by Dodor Bolder ( a Member of our Society') who was then at 
Blechington , to be obferved by thofe in the further part of the 
Garden, fome very difcernable time before it was obferved by 
thofe in the Houle ; creeping forward from the one place to 
the other. What other places in the Country if was obferved 
at,I have not been informed: but at Oxford ('which, it feems, 
was about the skirts of it) it was fo finally as would have been 
hardly noted at all*, had not the notice, taken of it abroad, infor- 
med us of it. 
Upon this Occafion,it will not be uufeafonable to give fome 
General accounts of what I have in my Thermff&pe and Baro~ 
[cope obferved. 
My Thermo fcope, being fitted fomewhat at adventures, I have 
found at the loweft to be iomewhat more than 12. inches high, 
in thefierceft time of the long Froft in the beginning of the 
laft year 1 66 5% and about 27 Inches high, at the higheft, in the 
hotteft time of the la fit Summer : .( which I mentiou 5 that it may 
appear at what temperature in proportion, the Air was at the 
time above-mentioned.) But I muft add withal!, that this Band- 
ing fo 9 as never to be expofed to the Sun,butin a room, that has 
a window only to the North, it would have been raifed much 
higher than 27* inches, if it were put in the hot Sun-fhine in 
Summer ; this, as it is placed,giving therefore an account onely 
of the Temperature of the Air in general, not of the immediate 
heatof the Sun-fiiine. 
This Inftrumentjthus fituated, when it is about 1 5. inches, or 
lower,isfor the mo ft part hard froft } but feldom a froft, if high- 
er than 1 6 . Yet this l have often obferved, that the Air by the 
Thermo fcope has appeared confiderably colder ( and the liquor 
lower) at fonietimes when there is no Froft, than at fome other 
times, when the Froft hath been confiderably hard. In
