408 Capt. Kater's experiments for determining the variation 
Latitude of Shankl in Farm. 
Having observed for the latitude of Arbury Hill, at the 
station itself, it was my intention to have done the same at 
Dunnose, but this, from the distance of the station, and the 
difficulty of the ascent, I found impracticable. My observa- 
tions therefore were made on a spot which was 20 feet south 
of the chimney of the summer-house in which the pendulum 
was placed. Previously to quitting London, the transverse 
level of the repeating circle was adjusted so as to render any 
correction unnecessary, and the axis carrying the telescope 
having been tightened, the index error was again carefully 
determined, and found to be 13". The observations were 
made under circumstances peculiarly favourable, and though 
those forming the second series are few in number, in conse- 
quence of the pole star having been frequently obscured by 
light clouds, I consider them as unexceptionable. The cor- 
rection of the mean polar distance for precession, 8cc. was 
kindly supplied by the Astronomer Royal. 
By altitudes of the sun, given in the Appendix, the chro- 
nometer was fast on the 10th of May 4”. 39 s , 7, its daily rate 
being — i ",78.
