lab ARCTIC EXPEDITION.

(TO THE EDITOR OF THE "SPECTATOR."]

:Sia,—My attention was called a few days ago to the paragraph in your edition of January 31st, in reference to the Arctic Expe- dition, and I would, on behalf of myself and the Committee, thank you much for the kind encouragement you gave to the undertaking. Will you, however, allow me to correct one little -error of your reporter? I did not say that the centre of the .earth was 26 miles nearer to the Polo than to the Equator, but that "the diameter passing through the Equator was a little more than 26 miles greater than the diameter from Pole to Pole." The centre is, therefore, about 131 miles nearer to the Poles

than to the Equator.—I am, Sir, am. SAMUEL Knees.
