I have been informed that the gentleman in charge of the stud of King Charles X. availed himself of the knowledge of this fact, and allowed only half the usual quantity of water to the horses under his charge, and that this plan was attended with the most satisfactory results, the horses being thereby able to endure a greater amount of fatigue than under a full allowance of water. To return to the cases of cure. Madam C., a landed proprietor, living in the Rue de la Concorde, at Paris, went to take the waters in Germany, in the year 1851. On her return, she made trial of my system, on account of excessive corpulence. Meeting with the usual success, she thought it would be of great advantage to a young lady, a friend, whom she had left behind her at the watering place, and who was then in bad health. This young person, about twenty-three years of age, was very fat, and irregular in her menstrual periods. She was of lymphatic temperament, very pale, and rarely partook of meat: her ordinary food consisted of vegetables, sweetmeats, cakes and sweet fruits; water was her principal beverage. At the pressing instance of Madam C., Miss C. visited Paris, in order to be under my care. After following my directions for a fortnight, her health was much improved. Her parents then came to Paris, and I continued in attendance on Miss C. for three months. At the expiration of this time, she returned with her parents to Brussels. She had lost much of her fat, and had become regular. She ate meat principally, both at breakfast and dinner, and drank wine. I may lay claim, in the case of this young lady, to have effected a complete change of temperament. With but trifling menstrual flow, and great pallor, she was gradually progressing to a state of obesity, which would have proved entirely destructive to health, which would have ended in a total suppression of the menses, and ultimately in death. But now, having overcome her obesity, the menstrual flow has become normal in quantity, the digestive powers have resumed their functional activity, so that she can partake of meat and wine, and in every respect her constitution is fully restored. Should she marry, she will in all probability have a family, which would have been very doubtful had she married while in the previous obese condition; and if she have children, her accouchements will be comparatively free of danger, and her sufferings much less; for it is well known that very corpulent females have more difficult labours than those of ordinary _embonpoint_; while the offspring of the latter are at the same time healthier. The same rule applies in the case of the human female as with other mammalia; when fat, conception is of more rare occurrence; and when they do conceive, they are very liable to miscarry. When, however, they go to the full period of gestation, the progeny of a very fat mother is almost always lean, and possesses little vitality.
