WALKING IN CIRCLES - [To the Editor of the SPECTATOR."

Slat,- --With reference to the correspondence on the above in your issue of October 31st, a theory is put forward that walking in circles may be due ton bias caused by people being longer one side than the Other.. Many years ago I was once lost with a squadron of cavalry- in- -the desert in the Eastern Sudan. One of the troopers averred that he knew the way ; I felt confident that he did not. However the officer command- ing the squadron told him to lead the way, whilst the squadron and baggage camels followed him. -He started off. I remained halted and watched him. As I anticipated, before very long I it became clear that he was marching in a circle. Shortly afterwards he admitted that he didn't know the way. Now, that could not have been due to "one side being longer than the other," because we were on horseback. It must have been the rider who gave the bias imperceptibly to the horse's reins.—! am, Sir, &c., 8 Cannongate Road, Ilythe, Kent. - G. CUNNINGHAM.
