Her is an antique 2 volume set French medical books from 1818 titled "Traite De Matiere Medicale" which I think translates to "Treate on Materia Medical" written by Schwilgue. This is a 2 volume set. The books measure approximately 7 1/4 " x 5 1/2". Vol. 1 has 504 pages. It is missing the end pages in the front of the book. The second vol. has 520 pages. Both volume has damage to the front and back covers. There is also some browning and light water stains on some of the pages. Please check out the photos. If you have any questions, please feel free to email me. Thanks for looking and please check out my other antique books I have on ebay.
