I ftill continued, for Come time, to make my observations in 
the upper room, as before. For this purpofe I fixed up a little 
clock there, which may be called a journeyman, or fecondary 
clock, having a pendulum Twinging leconds, which after being 
well adiufted, would keep time very regularly for feveral hours. 
It had only a minute and fecond hands, and {truck every minute 
exadlv as the fecond hand came to fixty, which, was very con- 
venient for the counting of feconds ; more efpecially. in the 
obfervations made with the parallaftic telefcope it being im- 
proper, on account of the inftability of the floor, to get up 
from one’s feat, or to alter the pofition of the body confidently 
even to catch the fecond, till thofe obfervations were completed.. 
I reduced the times to that of the obfervatory clock by means, 
of my watch, with the fecond hand. The little clock, as well 
as the larger clock, which I fent with Mr Dixon to the Cape 
of Good Hope, was made by Mr. John Shelton. 
? December 4 th , I compared the moon s weftein limb with 
the three * of Aquarius, with refpeft to right afeenfion, and 
obferved her occult to the fouthern one. Jhe time is fet down 
according to the little clock, and the difference between that 
and the obfervatory clock is fet down by the fide ; the latter loL 
5 o feconds upon 24 hours, in one revolution of the fixed ftars, 
and the little clock kept very nearly the late of flder, p *im . 
In thefe obfervations the diredting wire was adjuiUd by t 
liars..
