lean man. Is it not reasonable as a conclusion of the most exacting philosophy that the train of cars that can bring loads of stone, brick and mortar until a great bulk is formed, can also carry away until this bulk disappears in part or all? This being my conclusion I will say by many years of careful observation of the work of creating bodies and destroying the same, that to add to is the law of giving size, and to subtract from is the law of reduction. Both are natural, and both can be made practical in the reduction or addition of flesh, when found too great in quantity, or we can add to and give size to the starving muscle through the action of the motor and nutrient system conveyed to, and appropriated from the laboratory in which all bodily substances are formed. Thus the philosophy is absolute, and the sky is clear to proceed with addition and subtraction of flesh. I believe I am prepared to say at this time that I understand the nervous system well enough to direct the laboratory of nature and cause it through its skilled arts to unload, or reduce, he who is over-burdened with a super-abundance of flesh, and add to the scanty muscle a sufficiency to give power of comfortable locomotion and other forces, by opening the gate of the supply trains of nutrition.
