T (hall now lay before your Lordfhip the tranfifs, 
which I took of the Sun, contained in the following 
table ; the firfl column of which, exprelfes the day 
of the month of the obfervation : the fecond, tha 
time fhewn by the clock, at the inflant of the tranfit 
of the Sun’s center, acrofs the middle vertical wire of 
the inflrument, on that day : the third column is 
made from the fecond, by applying the equation of 
time thereto. Therefore, the differences between 
the numbers in the fecond column, fhew the rate at 
which the clock gets upon the Sun? and the dif- 
ferences between the numbers in the third column 
lhew the rate, at which the clock gets upon mean 
time.
