Your Lordfhip will perceive, that, from April 25 
to April 27, the clock got 4™ i f , upon mean time, 
in two days; which is at the rate of 2 m o f 4- per day. 
In like manner, from the differences between the 
following obfervations, the clock appeared to get per 
day i m 58 f 4, i m 59 f ,7, im 59 f > 1 > 59 f > i m 58 f ,6; 
the mean of all which is i m 59 f ,2. The thermo- 
meter in the clock-cafe, at a medium, during this 
time, flood at 72^ 
The obfervations, as your Lordfhip will perceive, 
agree fo near together, in giving the fame rate of the 
going of the clock, that there is fcarce room for pre- 
ferring one to another. But, from the circumflances 
of the obfervations, I fhould rather cbufe to deduce 
the rate, at which the clock gets per day, from the 
tranfits of April 30 and May 8 ; which is exactly
