In the month of August, 1849, M. Guénaud, a master baker, still residing in the Rue St. Martin, Paris, presented the following appearance:--Age, twenty-eight years; height, four feet eleven inches. His obesity was such that he was scarcely able to walk, and whenever he attempted to do so, suffered from difficulty of breathing. When standing for a short time, he experienced great pain in the region of the kidneys. He was incapable of superintending the workshop and attending the flour market, duties which devolved upon him as manager of an extensive bakery. An unconquerable drowsiness overcame him the moment he sat down, and rendered him unable to attend to his numerous accounts. When in bed he was obliged to be propped up by a number of pillows, in a semi-recumbent position; for if his head happened to be too low, he suffered from vertigo, dizziness, &c. His countenance was suffused, and the veins of the head, especially the temporal, were more than usually distended. The slightest exercise was attended with excessive perspiration. The cerebral circulation was so much impeded, that he could not bear even the pressure of a hat; and asserted that he would not dare to stoop, even were it to insure him a fortune. In this distressing condition he sought the advice of a physician, under whose directions he was repeatedly bled, and freely purged. He was recommended to live upon the smallest quantity of food that nature would permit, and to diet chiefly upon watery vegetables, such as cabbage, turnips, salad, spinach, sorrel, &c., and only occasionally to partake of a very small quantity of meat. He was also directed to use active exercise, to work in the bake-house, and to take long walks. But he found it impossible to follow the latter part of this advice, on account of a feeling of impending suffocation, and severe pains in the region of the kidneys. He was therefore recommended to take exercise on horseback; but this even could not be borne, and in spite of every effort his obesity was constantly on the increase. At last he could not walk a quarter of a mile, and was obliged to confine himself to the house, passing his time in a listless, somnolent condition, entirely deprived of all mental and bodily energy. His mother, who lived in the neighbourhood of Paris, having seen the advertisement of my book upon Obesity, and thinking of the melancholy condition of her son, procured a copy and read it. She thereupon brought her son in a carriage to my office. Guénaud was quite out of breath from having to ascend one pair of stairs; he seated himself upon a sofa in my room, and soon fell asleep. Occasionally he would wake up, and take some part in the conversation. The mother and her son went home, and on the following day Guénaud began to carry out the directions he had received from me; and at the end of thirteen days he was able to walk from the Porte St. Martin to La Chapelle, where his mother resided, delighted at having
