Old antique, very early pre-Civil War copy of Comstock's Philosophy, a collection of -natural philosophy- (now known as science). Looking through this book we saw it covering topics such as physics, mechanics, optics, astronomy, gunnery, electro-magnatisim and much more!
This is leather bound with about 360 pages with engraved illustrations. This is in very nice condition for a piece of this age. It does have some wear to the leather and foxing and spotting to the pages.
