Dr. Moore's case is peculiarly interesting, inasmuch as for some years he was regarded by many of his friends, as near a fatal consumption. In the February preceding the date of his letter, I met him in a stage-coach, and was struck with his healthful appearance, and interested with the account of his restoration. The following letter from the same gentleman confirms the views contained in his first communication.

"Wells, May 7, 1836.

"Dear Sir,—

"Yours of the 3d inst. has just been received; and in answer to your inquiry I have to say, that my health is better than when I last saw you in 1833; although, since that time I have been afflicted with all my former unpleasant symptoms, viz. loss of appetite, debility, tremors, dizziness, palpitations of the heart, anxiety of mind, melancholy, &c. &c.

"You may ask what could be the cause of all these unpleasant sensations. I will tell you. It was returning to the gratification of a depraved appetite in the use of tobacco; and I have no hesitancy in declaring it as my opinion, that could the causes of the many acts of suicide, committed in the United States, be investigated, it would be found, that many instances were owing to the effects of tobacco upon the nervous system.

"It is now nearly two years since I have had any thing to do with this enemy of the human race, and my health has never been better. I have a good appetite for food. My dyspeptic affection troubles me so little, that I hardly think of it. I never weighed so much before by several pounds.

"One of the persons of whom I wrote before, is still in this vicinity, and uses no tobacco; he enjoys uninterrupted health. The others do not now reside in this place.

"Yours,
"E. G. Moore."
