Dear Argosy. THANK YOU very very much. I ordered the book "A Case of Removal of the Lower Jaw, for OsteoSarcoma of Immense Size" by George C. Blackman. I was pleased beyond words just to think that I was getting an original copy of a book that my great great grandfather wrote. When it arrived it was an even bigger treasure for me, as his own handwriting was in the upp right corner of the cover, giving the book to a fellow colleague. Thanks again so very much for helping me bring my ancestry searching a little closer and more personal. "
