First Principles of Chemistry, for the Use of Colleges and Schools. By Benjamin Silliman and printed in Philadelphia by H.C. Peck and Theodore Bliss. 1866. In fair condition, with rubbing and wear and tear to boards and spine. First page torn at top corner and I think that a page to appendix in back might be missing, as I see a stub of a page at very end. That might have been a blank page, but I don't know. General age-related toning to pages, along with periodic foxing, other spots and wear.
