* Observations considered good. + Observations considered bad or doubtful. 
Aug. 184 8h, A first attempt to change the poles of the needle failed, probably from the wrong end of the needle being taken. 
Sept. 124—Oct. 64. The dip instrument and needles sent to Messrs Adie and Son, Edinburgh, to be adjusted. 
Oct. 9°%—Noy. 204. The observations in October were so unsatisfactory that they were discontinued for some time. 
Nov 244 3, Before this observation the instrument was levelled, as it was previously slightly out of adjustment.
