His library, which is quite well known to the medical scholars of the country, contains about four thousand volumes, including many of the rarest books now existing, in most of the departments of the healing art. There is, perhaps, no collection of the medical classics equal to his to be found in private hands in the United States. It includes large series of works illustrating the development of anatomy, surgery, materia medica and medicine, from the earliest periods to the present time. His collections of works pertaining to the history of medicine, and the biography of physicians and surgeons, are quite extensive.

The doctor has also been to great pains and cost in collecting the bibliography of teratology, a subject to which he has bestowed special attention. Mention should also be made of his collection of medals relating to the medical profession ; and, also, of his collection of more than one thousand engraved portraits of celebrated physicians, surgeons, anatomists and medical authors. His library is enriched by a wellselected collection of medical essays, embracing about three thousand pamjihlcts, all carefully catalogued and indexed. His private museum contains collections of typical objects in conchology, palseontology, mineralogy and archaeology. The latter department is quite rich in specimens of the stone implements of the American aborigines.

It is to Dr. Fisher that we are indebted for the history of the town of Ossining, which forms one of the chapters of this work.
