This book, "An address upon the progress of medicine, surgery and hygiene, during the last 100 years delivered by request of the St. John Mechanics' Institute, on Feb. 4th, 1884. 1", by William Bayard, is a replication of a book originally published before 1884. It has been restored by human beings, page by page, so that you may enjoy it in a form as close to the original as possible. This book was created using print-on-demand technology.
