XXVII. Obfervatlons made at Chiflehurfl:, in Kent, in the 
Tear 1774 . By the Rev. Francis Wollafton, LL.B. 
F.R.S. 
Rcdcle, Mar. i6,T y AVING now complcated my originaf 
775* J71 cledgn, and kept my clock going for a 
third year, without the lealf touch of the oil, or any al- 
teration whatfoever, I prefume the refill t of my obfer- 
vations to afcertam the rate of its going, may not be an 
unacceptable addition to the former papers on that fub- 
je 6 l, delivered to this Society. The regular difference 
between the fummer and winter months, and fome degree 
of fimilarity between thofe differences, feems to fhew 
a regularity in the caufe. What that may be, is not 
fully to be afcertained hereby ; though it feems to have 
been difference of moifture, rather than of heat. By 
comparing thefe three laff years with that which I firfl 
gave, when the clock was in fbme degree foul, it feems 
as if it were moft affedred when the work is^ clean. Yet 
is not that quite certain ; for the differences, which de- 
creafing gradually in the following table, would juftify 
this conclufion, it may be obferved, increafe again in 
the lafl inftance.
