Page 218 - As to the first question, we may observe that what we call a mind is nothing but a heap or collection of different perceptions, united together by certain relations, and supposed, though falsely, to be endowed with a perfect simplicity and identity.
Page 228 - Pluck from the memory a rooted sorrow, Raze out the written troubles of the brain, And with some sweet oblivious antidote Cleanse the stuff d bosom of that perilous stuff Which weighs upon the heart ? Doct.
Page 259 - ... 6. The non-nitrogenous matters of food, which find their way into the blood, yield up all their potential energy as actual energy ; the nitrogenous matters, on the other hand, leave the body with a portion (one-seventh) of their potential energy unexpended. 7. The transformation of potential energy into muscular power is necessarily accompanied by the production of heat within the body, even when the muscular power is exerted externally. This is doubtless the chief, and probably the only source...
Page 259 - After the supply of sufficient albumenized matters in the food of man, to provide for the necessary renewal of the tissues, the best materials for the production both of internal and external work are non-nitrogenous matters, such as oil, fat, sugar, starch, gum, etc.
Page 231 - My medicines are a powder, a decoction, and pills. The powder consists of egg-shells and snails, both calcined. The decoction is made by boiling some herbs (together with a ball which consists of soap, swine's cresses burnt to blackness, and honey) in water. The pills consist of snails calcined, wild carrot seeds, burdock seeds, ashen keyes, hips and hawes, all burnt to blackness, soap, and honey.
Page 249 - All these organized tissues, all the parts which in any way manifest force in the body, are derived from the albumen of the blood; all the albumen of the blood is derived from the plastic or sanguigenous constituents of the food, whether animal or vegetable. It is clear, therefore, that the plastic constituents of food, the ultimate source of which is the vegetable kingdom, are the conditions essential to all production or manifestation of force, to all those effects which the animal organism produces...
Page 259 - We thus arrive at the following conclusions : — 1. The muscle is a machine for the conversion of potential energy into mechanical force. 2. The mechanical force of the muscles is derived chiefly, if not entirely, from the oxydation of matters contained in the blood, and not from the oxydation of the muscles themselves.
Page 259 - ... 3. In man, the chief materials used for the production of muscular power are non-nitrogenous ; but nitrogenous matters can also be employed for the same purpose, and hence the greatly increased evolution of nitrogen under the influence of a flesh diet, even with no greater muscular exertion. " 4. Like every other part of the body, the muscles are constantly being renewed ; but this renewal is not perceptibly more rapid during great muscular activity than during comparative quiescence. "5. After...
Page 259 - The mechanical force of the muscles is derived chiefly, if not entirely, from the oxidation "of matters contained in the blood, and not from the oxidation of the muscles themselves. 3. In man, the chief materials used for the production of muscular power are non-nitrogenous ; but nitrogenous matters can also be employed for the same purpose, and hence the greatly increased evolution of nitrogen under the influence of a flesh diet, even with no increase of muscular exertion. 4. Like every other part...
Page 250 - Finally, in a masterly review of the present relations of chemistry to animal life, published in March last, * Odling says, page 98 : " Seeing, then, that muscular exertion is really dependent upon muscular oxidation, we have to consider what should be the products, and what the value of this oxidation.
