At the conclusion of the given treatment of each disease, we have given the size of the dose and its frequency of rep etition, but as this must depend largely upon the peculiar ities of each individual case, the reader will often have to use his own judgment in regard to the matter; meanwhile, he should read carefully the article on Administration of the Medicine and Repetition of the Doses. We have also pointed out a suitable diet to be adopted in each particular case, and given specific directions in regard to bathing, ven tilation, and exercise which will be found of especial interest to the lay practitioner.
