Our minister, Rev. B. L. Swan, during the whole of two years of his theological studies at Princeton, made crackers and water his only food, and was in good health. Mr. Hanover Bradley, of this village, who has been several years a missionary among the Indians, has, for I think, eight or ten years, lived entirely on vegetable food. He had been long a dyspeptic. There are some other cases of less importance, and probably very many in New Haven; but I am situated a mile from the city, and have never inquired for vegetable livers. Yours, etc., LESTER KEEP. LETTER VII.--FROM DR. HENRY H. BROWN WEST RANDOLPH, Vt., Feb. 3, 1838. DEAR SIR,--It has been about two years and a half since I adopted an exclusively vegetable diet, with no drink but water; and my food has been chiefly prepared by the most simple forms of cookery. Previously to this, I used a large proportion of flesh meat, and drank tea and coffee. I had much impaired my health by such indulgences. I hardly need to say that my health has greatly improved, and is now quite good and uniform. I think that physicians, in prescribing for the removal of disease, should pay much more regard to the diet of their patients, and administer less of powerful medicine, than is customary with gentlemen of this profession at large. Yours, etc., HENRY H. BROWN. LETTER VIII.--FROM DR. FRANKLIN KNOX. KINSTON,[5] N. C., June 23, 1837. DEAR SIR,--Your letter of the 22d July has been hitherto unanswered, through press of business. I consider an exclusive vegetable diet as of the utmost consequence in most diseases, especially in those chronic affections or morbid states of the system which are not commonly considered as diseases; and I think that, in these cases, such a diet is too often overlooked, even by physicians. Yours, truly, F. KNOX. LETTER IX.--FROM A HIGHLY RESPECTABLE PHYSICIAN. [The following letter, received last autumn, is from a medical gentleman, in a distant part of the country, whose name, for particular reasons, we stand pledged not to give to the world. The facts, however, may be relied on; and they are exceedingly important and interesting.] DEAR SIR,--Your letter was duly received. I proceed to say that, since I settled in this town, my attacks of epilepsy[6] have occurred in the following order: 1833. Nov. 18. One at 11 P. M. Severe. " 19. " " " " 24. Nineteen, from 4 A. M. to 3 P. M. Frightful. 1835. Jan. 13. One at 4 A. M. } " 15. " " } Milder. " 16. Two at 2 and 4 A. M. }
