666 The Account of a 



St. Andrew's or the Old Church, at Plymouth. 



The angle at Butterton, between the Old Church tower and 

 Kit Hill, is 37° 45' 5",2 ; its bearing, therefore, south-west from 

 the meridian, is 75 i' 56" ; consequently, its distance from the 

 meridian is 57505 feet, and from the perpendicular 15374 feet. 

 These respectively subtend 0/ 24", and 2' 32",i : hence, its lati- 

 tude becomes 50 22' i3",6\ and longitude 4 7'3i",6= i6' m 

 3o s ,i in time, west of Greenwich. 



As it is of very great importance that the truths of the con- 

 clusions given in this Work should receive support, wherever 

 I can find it, I think it right to mention the result of his 

 Excellency the Count de Bruhl's endeavours to ascertain the 

 longitude of Plymouth, by means of chronometers. The fol- 

 lowing is a copy of his communication, made in the year 1795.

* It is, perhaps, right to observe, that Mr. T. Mudge's transit, at Plymouth, was 

 made by the late Mr. Bird, and properly set up between stone pillars. The clock, the 

 entire work of his own hands, was a most excellent one.
