The Account of a 
SECTION FIRST. 
article i. Of Particulars relating to the Operations of the 
Tear 1795. 
In an early part of this season, from the necessity which 
existed of completing the map of Kent, mentioned in the 
preamble, we had conceived that our former intentions, of 
continuing the survey towards the west, would for the present 
be relinquished; as it was not imagined that the telescope 
of the small circular instrument, then in the hands of Mr. 
Ramsden, could be applied, with good effect, in observing 
staffs erected on very distant stations. 
From the obvious importance, however, of adhering to the 
first resolution, it was determined that a trial should be made 
of the excellence of this instrument, in the construction of 
which extraordinary pains had been taken, by operating with 
it in Kent, and using it for those purposes to which, if the 
object before spoken of had not been in view, the great theo- 
dolite would have been necessarily applied. 
This smaller theodolite, therefore, as a substitute, was in 
May taken into Kent by Mr. Dalby, and Mr. Gardner, chief 
draughtsman in the Tower ; the assistance of the former being 
necessary, as the stations in the series of 1787 were for the 
most part unknown to the latter gentleman. 
As the former paper, relating to the trigonometrical survey, 
could not be presented to the Royal Society before the 4th of 
June, the business did not commence till the 12th of the same 
month. The party then left London, and the instrument was 
taken to Bull Barrow, in Dorsetshire.
