 Below are the times of the beginning, middle, and ending of the eclipse, as 

 predetermined by a projection of it for Liverpool, from Meyer's tables, which 

 were the apparent times ; reducing the observed equal times to the apparent, by 

 subtracting 3 minutes 48 seconds (which he supposed was the equation of time) 

 from the equal times as observed by the clock and two watches which kept 



equally going together.

XX. Observations on the Eclipse of the Sun, April 1, 1764, at Brompton- 

 Park, By Mr. Samuel Dunn. p. 114. 



At 9*" 4™ 29' per watch, thought he saw a little dull tremulous vibration ob- 

 trude itself on the limb of the sun ; and, 

 it became a little more sensible ; and, 

 a little more sensible ; but it was 



per watch before he was certain the sun's limb was touched by 

 the limb of the moon ; and. 

 At 9 4 33 he plainly saw, through a telescope, and the thin vapours of the 

 atmosphere, the least visible dent, perfectly well defined in the 

 sun's limb. 

 The watch was but one second of time before the sun at the time of obser- 

 vation, for Brompton park, which is exactly one mile from Hyde-park corner, 

 in the way towards Kensington. Clouds prevented the end of the eclipse from 

 being observed.
