Excerpt from Collected Contributions on Digestion and Diet The matters treated of have been thrown together into four groups or sections; and the materials have been subjected to some amount of rearrangement. By this means a certain degree of order and coherence has been given to the entire work; but no attempt has been made to produce a systematic treatise. The articles have all been carefully revised; and repetitions have been eliminated as far as was practicable; but no substantial changes have been made in the subject matter. The present edition is enlarged by the addition, in the form of an appendix, of an article on the Opium Habit in India. This article first appeared as an 'annexure' to the Report of the Royal Commission on Opium, published in 1895. It is here reproduced as a contribution to our knowledge of a group of quasi dietetic substances, which includes alcohol, tobacco, tea and coffee, concerning the true significance of which we are still greatly in need of enlightenment.
