of an Arc of the Meridian. 
canvas sides, I had ready means, at all times, of turning the 
telescope to that object. And I can take upon me to say, that 
during the whole of my stay at this station, I never found the 
instrument out of the plane of the meridian more than half a 
minute. 
Of the 27 stars observed at Dunnose, 17 were observed at 
this station; they were the following, viz. ( 3 , y, 4 $d, qfc, 51, 
16, p, Draconis; ik, iov, Cygni ; £, Ursie; 22r, 85^ 52, 
Herculis ; a. Persei, and Capella; 
As the weather for most part of the time proved favourable, 
the observations were completed on the 22d of July ; and, as 
there appeared to be sufficient time, between that period and the 
arrival of the season which would necessarily terminate my 
operations, to carry on my meridional line to the Tees mouth, I 
reconnoitered the country in that quarter, and selected the sta- 
tions all the way between it and Clifton. 
On the 23d of July, the instrument and observatory were 
taken down, and the large theodolite erected over the point. 
White lights were sent to the distant stations, and were all 
observed, except those fired on the 30th day of the same month ; 
and, as the night on which those lights were burnt was remark- 
ably clear, and it was therefore probable that some intervening 
land obscured the distant hill, I desisted from making any 
farther attempt towards the execution of the above scheme, as 
any greater loss of time might prevent me from making the pro- 
posed observations on Arbury Hill. I therefore sent the sector 
to this last-mentioned place, where it arrived on the 3d of 
September, and was erected on the 7th, the direction of the 
meridian having been previously ascertained, by two double 
azimuths of the pole star. But it is proper I should observe,
