moved forwards and backwards, as 'the time of the 
year required; on which the fame Hands fhewed Ap- 
parent Time like wife, according to the Equation Tables. 
This Method the Author owns he knew of. and appiyed 
the fame Motion to Pocket Watches iz or 14 Years 
ago, which I confefs I never did ; being well fatisfied 
that Watches with Springs and Ballances are very unfit 
to Ihew the minute difference, as it iucreafeth and de- 
creafeth, between equal and apparent Time. 
Soon after this Clock was fent to Spain, I made o- 
thers for Mr. ^lare which Ibewed Apparent Time by 
lengthning and fhortning the Pendulum, in lifting it up 
and letting it down again, by a Rowler fomew^hat in 
the form of an Ellipfis, through a flit in a piece of 
Brafs, which the Spring at the Top of the Pendulum 
went through* By this means every vibration of the 
Pendulum would agree to a Second of Time of the 
Suns apparent Motion ^ that Rowler which lifted up 
the Pendulum, and let it down again, being continually 
moving about all the Year ; fo that it may feem very 
ftrange that this Author never heard of it, fo many 
Years after they were made ; For one of thofe, and 
not the firft, made with the rifing and fetting of the 
Sun, Mr. Quare fold to the late King William, and it 
was fet up at Hampton-Court in his Life time, where it 
hath been ever fince. This contrivance of lengthning and 
fhortning the Pendulum, I thought of feveral Years before 
I made any of them. Since then 1 have made others for 
Mr. ^are likewife, which (hewed the difference between 
equal and apparent l ime according to the Equation Ta- 
bles, by a Hand moving both ways from the top of a 
Circle; on one fide fhewing how much a Clock keeping 
equal Time ought to be fafler than the Sun, on the 
other fide how much flower.
