It is difficult to say how much of the usefulness of Dr. Emmons had been lost, if he had harbored that anile bigotry which would banish from our spiritual mechanism the lubricating oil of joy, without which the wheels drag, and the machine wears out. A man who could say, when nearly a century old, “ I never took an hour’s exercise for the sake of exercise, in my life ;” who had studied on an average ten hours a day for more than half a century ; such a man would have become a morbid hypochondriac, or an obtuse plodder, unless his mind had received relaxation and tone, and elastic versatile energy, from the use of that gift which distinguishes men from brutes, and sane men from idiots. Indeed, there must have been some such recreation, in order to perpetuate his life through so many eventful periods, amid so many perplexing and fatiguing studies.
