A high C.G. also tends to swing outward from the centre of the turn. It will tend to make the aeroplane bank the wrong way, and such effect must be remedied by means of the ailerons. The pleasantest machine from a banking point of view is one in which the C.G. is a little below the centre of drift. It tends to bank the aeroplane the right way for the turn, and the pilot can, if necessary, perfect the bank by means of the ailerons. The disposition of the keel-surface affects banking. It should be, in effect, evenly divided by the longitudinal axis.英文原著 · 《The Aeroplane Speaks》

A well-marked naso-labial fold is formed, which runs from the wing of each nostril to the corner of the mouth; and this fold is often double in old persons.英文原著 · 《The Expression of Emotion in Man and Animals》
