For some inexplicable reason the sense of smell does not hold the high position it deserves among its sisters. There is something of the fallen angel about it. When it woos us with woodland scents and beguiles us with the fragrance of lovely gardens, it is admitted frankly to our discourse. But when it gives us warning of something noxious in our vicinity, it is treated as if the demon had got the upper hand of the angel, and is relegated to outer darkness, punished for its faithful service.
