SURVEY OF THE BRITISH ISLES FOR THE EPOCH JANUA.RY I, 1886. 127 
48a. Stornoway (Arcl Point). September 4 and 5, 1884, and August 19, 1885, 
A. W. E. and T. E. T. (60, 74); aud August 14, 1888, T. E. 1’. (61, 83), 
A. W, E. (60, 74). Lat. 58° 12' 10"; Long. 6° 23' 40". On the top of the 
hillock on the Point. The Declinations taken on this spot agreed well with that 
obtained in the Castle Grounds, and were therefore regarded as normal. In 
1888, simultaneous observations were made by both of us, which agree among 
themselves but differ considerably from each other. Dr. Thorpe occupied the 
old station near the top of the hillock, Professor Eucker was about 50 yards 
distant on lower ground and nearer the mainland. There can be little doubt 
that the station is disturbed.
