There is a sentence in the Latin grammar: “Too much confidence is wont to be a calamity.” This is no doubt true, but it must be remembered that too little confidence is certain to be one; and though to inculcate a frame of mind is perhaps a useless task, yet there is, as it were, a correct attitude for winning, just as a straight bat is the correct attitude for a yorker, and it seems in the main to be this. Never despise your adversary, but whoever he is treat him with respect. Cultivate a belief in your chances of winning, but remember that though you are not beaten till the last set has been finished, or the eighteenth hole putted into, yet neither is he. Husband your resources, unless things are positively desperate. And so good luck to you. But if you have bad luck, remember you are a gentleman, or, if you are not, that you have an excellent opportunity for making other people think so. CHAPTER X. REMEDIAL. We have already spoken of the constant need of light, in order that the body may be healthy, and have suggested some simple rules about the use of heat, either in Turkish or ordinary baths. But these natural aids to health may, as we have said, be used as directly remedial agents in case of disease, or to correct existing bodily defects. Much scientific investigation has lately been made into the healing properties of electric light, whether used merely as light, or, as some hold, to put external electricity into the body; and it has been found to cure, not only weakness of the system, acting as a tonic, but even such tubercular diseases as lupus. We should not, however, recommend anyone to dabble with electricity, still less to go through a course of treatment except under skilled medical supervision, and this treatment by electricity comes outside the scope of this book.
