As a result of my investigations I wrote a series of articles for the _Detroit Tribune_ on the bad habits which cause diseases, insanity, and deformity; and, as opportunity offered, I gave lectures upon such subjects; and finally I wrote a work entitled the "Avoidable Causes of Disease," of 348 pages, of which I printed several editions, the first of which was in 1859, and furnished to different publishers, and advertised to a limited extent; after that it was published for several years by Messrs. Mason Brothers, of New York; after which it came into my hands again. I also wrote a pamphlet of 48 pages on "Marriage and its Violations," which, for a time, was bound separately, but afterward was bound with the "Avoidable Causes of Disease." In all, eleven editions of the work have been printed; the last edition was printed by Messrs Boericke & Tafel, of Philadelphia, who will probably publish any future editions which may be demanded. I soon found, what my publishers found after me, and other writers and their publishers have found, that it does not pay to advertise books which contain the greatest amount of practical and useful information which is calculated to benefit readers, especially if they call in question the bad habits and evils of life in which so many people indulge; consequently, feeling that a work treating of diseases and their cure, in which I could advertise my first work and call special attention to it, would sell more readily, I wrote a book of 404 pages, entitled "Family Homoeopathy," in which I took great pains to carefully describe in few words the various diseases, and gave as definite and positive instruction as was practicable to guide laymen, so that harmless homoeopathic remedies might take the place of drastic drugs and injurious domestic remedies, which are so frequently used when it is thought not necessary to call a physician, or before his arrival when called. At the end of this volume I inserted a carefully prepared table of the contents of the "Avoidable Causes of Disease," occupying three pages, and referred not unfrequently to that work when treating of various diseases. With but very slight efforts, and no advertising on my part, "Family Homoeopathy" sold very well--principally through the different homoeopathic pharmacies in our country; and this increased the sale of "The Avoidable Causes of Disease" very materially, as I expected it would. Seventeen editions of "Family Homoeopathy" have been printed and sold, the last edition by Dr. E. R. Ellis, of Detroit, Michigan, who will continue to print and supply applicants as wanted.
