.AJ{elation concerning the late Earthquake «w Oxford ; together 
Tvitb feme Obfervations of the fealedf'Featbefglafs, and the Bare' 
meter, hoth upon that PhsenomenoDj^^i^V^ General. 
This Relation was communicated by the excellently learned 
Dr. Wcillis, as follows : • 
On the 19. of January 166$. Stylo jingli/e (or jf^w, 19. 1666. 
Jiylo novo) at divers places neer Oxford, was obierved a fmall 
Earthquake (^as at Blechington, Stanton-St, Johns , Bril^Scc.) to- 
wards evening. In 6^Ar/ari it felf 5 I doe not hear, that it was 
obferv'd to be an Earthquake j yet I remember about that tfoae 
("whether preci(ely then or not, I cannot fay) I took notice of 
forae kind of odde fliaking or heaving, I obferved in my ftudy^ 
but did impute it to the going of Carts or Coaches , fuppofed 
to be not far off 5 though yet I did take notice of it , as a little 
differing from what is ufualon fuch occafions ; (and wondered 
the mdrg, that I did not hear any:) But not knowing, what elfe

Notes concerning my Thermofcope and Barofcope^to fee if any al- 
teration confiderable had then happened. 
My Thermofcope confifts of a round large Glafs 5 containing 
about half apint or more; from whence iflues along Cylin- 
drical neck of Glafs, about two foot and a half in length, and 
lefs than a quarter of an inch diameter; which neck was her* 
wetically fealed at the top, to exclude communication with the 
External Air ; but before the fealing of it,the whole Glafs was 
filled with Spirit of Wine (tinged with Cechineel , to make it the 
more difcernable to the Eye^fo warmed,that it filled the whole 
content of the Glafsibut afterwardsjas it copled^did fo fubfide, 
as to leave a void fpace in the upper part of the Neck. Which 
Inftrumentjfo prepared, doth by the riling or falling of the tin- 
ged liquor in the neck(confequcnt upon the expanding or con- 
trading of the whole liquor contained in it and the Ball be- 
low)give a very nice account of the Temperature of the Air,
