DEAR MR. PUNCH,--I read that two new cures for sea sickness have just been discovered: the one the eating of bananas; the other, found out by Professor Heinz, of Erlangen, who declares that the malady proceeds from the lobe of the brain, and that to avert it one has only to breathe freely. As to the Professor's theory about breathing freely, I can safely assert that I never open my mouth so wide as when crossing the Channel, but the experiment is an unpleasant failure.
