time; additive when the sun is receding from the elevated pole, 

 and vice versa. 



Note, when the index in the last result turns out to be 8 or 9, 

 which can happen only when the sun is very near the solstice:, 

 the equation must then be considered as a fraction.

By these the clock was too fast for mean time 36" 4, and 

 by a comparison with those of May the 1st, the clock loses at 

 the rate of 3" 6 per day,, which correction being applied to 

 the occultation of e leonis, we shall have the immersion at 

 b" 46' 30" 2 mean time, or 8 h 49' 11" 37 apparent time.
