Note 3 — I. PHYSIOLOGY.

I can from personal experience state, that being subject when younger to swelling of the upper lip from cold, previous to entering Switzerland I allowed my moustache to grow. During six weeks excursion on foot, exposed to all weathers and stopping for none, being at one moment in warm valleys and a few hours afterwards at the top of ice-clad mountains, I never felt the least uncomfortableness about the mouth. When on returning home, however, I was foolish enough to shave, I paid dearly for the operation.
