On the 22nd of the same month Mr. Roberts wrote as follows:--"I weighed two hundred and six pounds, and now weigh only one hundred and ninety-two. I measured forty-three inches in circumference, and now only thirty-one inches. I am delighted with the success which has attended your system of treatment, and am happy to be able to inform you of it. Accept my sincere thanks, for I am indebted to you for a condition which I despaired of ever again attaining. Yours truly, "ROBERTS." The following letter has been also received: "SAINT DIÉ, 24th Nov., 1850. "SIR,--Having read your book on the treatment of obesity, I wish to ask if you will undertake my case, although living at a distance of three hundred miles from Paris. I am fifty years of age, and possessed of a vigorous constitution. Since I have retired from business, now ten years ago, I have steadily increased in corpulence; my present weight being one hundred and eighty-nine pounds. I am troubled with an affection of the heart, shortness of breath, and my legs swell, especially when not taking much exercise on foot. I am not fond of walking, since it induces great fatigue. My belly has become much enlarged, and I am greatly troubled with drowsiness. For breakfast I use coffee with milk, although I am not fond of it, but I find that it prevents headache, to which I am otherwise subject, &c. You will oblige me by sending the necessary instructions, if you can take charge of my case, by the bearer of this letter, together with such medicines as you may direct. "Yours, &c. K." In answer to Madame K., I sent her the medicine, together with the necessary information. On the 25th of February I received a letter, from which the following extracts are made:--"Your directions have been scrupulously observed for the past fifteen days. I take a daily walk in the mountains, and to-day was weighed. I have lost but four pounds: too small a reduction I fear; but perhaps due partly to my temperament. The medicine requires to be taken in larger doses, I think. Nevertheless I am well satisfied with the result thus far, being now free from those troublesome palpitations of the heart to which I have been hitherto subject." The 9th of April following this lady wrote: "My legs do not swell as they used to do, and the palpitations have ceased. I am delighted with this good result of your method of treatment."
