When you go out of doors on a cold, frosty morning, your nose is very likely to block up, because so much hot blood is pumped into these little steam-coils of blood vessels, in order to warm the air properly, that they swell until they almost block up the nostrils. The Sense of Smell.
Is it possible that the mere inhaling of air directly into the lungs, even though it be imperfectly warmed, moistened, and filtered, as compared with what it would be if drawn through the elaborate "steam-coils" in the nostrils for this purpose, can have produced this array of defects? It is incredible on the face of it and unfounded in fact.
