which are easy of digestion. For those who have good reason to believe that their "kidneys are weak," a diet largely made up of meat is ill-advised. Those organs are intimately concerned in its disposal in the system, and hence are overtasked if it is taken in too great a quantity. _Reasons Why a Strictly Vegetable Diet Is to Be Preferred to Animal Food._--The food which is most enjoyed, says a writer in _Longman's Magazine_, is the food we call bread and fruit. In my long medical career, I have rarely known an instance in which a child has not preferred fruit to animal food. I have been many times called upon to treat children for stomachic disorders induced by pressing upon them animal to the exclusion of fruit diet, and have seen the best results occur from the practice of reverting to the use of fruit in the dietary. I say it without the least prejudice, as a lesson learned from simple experience, that the most natural diet for the young, after the natural milk diet, is fruit and whole-meal bread, with milk and water for drink. The desire for this same mode of sustenance is often continued into after years, as if the resort to flesh were a forced and artificial feeding, which required long and persistent habit to establish as a permanency as a part of the system of every-day life. How strongly this preference taste for fruit over animal food prevails is shown by the simple fact of the retention of those foods in the mouth. Fruit is retained, to be tasted and relished. Animal food, to use a common phrase, is "bolted." There is a natural desire to retain the delicious fruit for full mastication; there is no such desire, except in the trained gormand, for the retention of animal substance. One further fact which I have observed--and that too often to discard it--as a fact of great moment, is that when a person of mature years has for a time given up voluntarily the use of animal food in favor of vegetable, the sense of repugnance to animal food is soon so markedly developed that a return to it is overcome with the utmost difficulty. Neither is this a mere fancy or fad peculiar to sensitive men or oversentimental women. I have been surprised to see it manifested in men who are the very reverse of sentimental, and who were, in fact, quite ashamed to admit themselves guilty of any such weakness. I have heard those who have gone over from a mixed diet of animal and vegetable food to a poor vegetable diet speak of feeling low under the new system, and declare that they must needs give it up in consequence; but I have found even these (without exception) declare that they infinitely preferred the simpler, purer, and, as it seemed to them, more natural food plucked from the prime source of food, untainted by its passage through another animal body. There are thirty vegetarian restaurants in London, and a vegetarian hotel is the latest move in the right direction. The time required to digest different kinds of food:--
