Here, daily, for almost a whole summer, I used my cold shower-bath, and, as I then thought and still believe, with great advantage. My consumptive tendencies were held at bay during the time very effectually. I was fortunate, indeed, in being able always, with the aid of a coarse towel and a little friction, to secure a pretty full reaction.
This season of cold bathing was when I was about sixteen years of age. I shall ever look back to it as one of the most important, not to say most interesting, of my experiences. Indeed, I do not know that in any six months of my life I ever gained so much physical capital—thus to call it; by which I mean bodily vigor—as during these six months of the year 1814.
I may also add here, that it has been my lot all my life long to learn quite as much from experiment and observation as in any other way. The foregoing experience gave me much knowledge of the laws of hygiene. Sometimes, while reflecting on this subject, I have thought of the assurance of the Apostle John, that he who "doeth truth cometh to the light," and have wondered whether the good apostle, along with this highly important truth, did not mean to intimate that the natural tendency of holy living was to an increase of light and love and holiness. And then I have gone a step further, and asked myself whether it was not possible that the doing of physical truth as well as moral, had the same tendency.
I have alluded to experience, or experiment. It is sometimes said that medical men are very much inclined to make experiments on their patients. Now, although I have a few sad confessions of this sort to make hereafter, yet I can truly say, in advance, that while I have made comparatively few experiments on other people, I have probably, during the progress of a long life, made more experiments on myself, both in sickness and in health, than any other existing individual. Whether I have learned as much in this way as I ought, in such favored circumstances, is quite another question.
CHAPTER VII.
MY FIRST SICKNESS ABROAD.
When I was about half-way through my nineteenth year, a desire to see the world became so strong that I made up my mind to a little travelling. Accordingly, having provided myself with an employment which would, without a great deal of hindrance, enable me to earn my passing expenses, I set out on my journey.
It was in the month of March, and near its close. The weather was mild, and the snow was fast disappearing—but not as yet the mud. In walking all day, my boots became soaked and my feet wet. The era of India rubbers had not then arrived. In truth, I went with my feet wet in the afternoon two or three days.
