CATCHING COLD.
[To TER EDITOR Or TER "SPECTATOR :l Sig,—It is a common experience in Northern India among officers who spend a considerable part of the cold weather under canvas that colds are very seldom caught while one is living in tents, but that if the camping is broken into by a few days spent in a bungalow a cold is very likely to be the result. This is in accordance with my own experience, and I have often heard the fact alluded to by others. It bears out the theory brought forward in the interesting letter of " X. X. X.," in the Spectator of January 7th. Many persons carefully avoid going into houses during their camping season on this account, even when convenient houses are available.—
