Many years ago, Dr. John Ellis, of New York City, author of the Family Homoeopathy, became financially interested in an enterprise for the manufacture and sale of lubricating oils. After a time it seemed desirable that he should give his personal attention to the manufacturing department of the business, which soon became so widely extended and absorbed so much of his time and energies as to necessitate his withdrawal from the practice of medicine, although he is yet an extensive writer on moral, medical and hygienic subjects. For this reason the future publication of the Family Homoeopathy has been committed to the writer, who will be pleased to supply physicians, pharmacists and others with the work. About the merits of the Family Homoeopathy little need now be said. Many thousands of copies have been sold and it is widely known as a standard work on homoeopathic practice, with none superior, to it, at the most its equal. Its simplicity of language exactly adapts it to family use, and its accuracy of descriptions of diseases and their treatment, renders it of invaluable aid to physicians as well as to others. It gives evidence on every page of great care in its production, by one of the most skilful physicians in this country. Being founded on the unchangeable laws of True Medical Science, its value will never decrease.
