Well's Natural Philosophy for the use of schools, academics, and private students. By David A. Wells, A.M. Fifteenth edition revised. Published in New York by Vision, Blakeman, Taylor, & Company in 1878.
This book was originally published in 1857. I found 16 copies online, in good condition or better priced from $8.00 to $46.00, with most around $32. Based on this I'd say your price is HIGH.
