"The Techno-Chemical Receipt Book", originally published in 1886. Basically a manual on how to make anything you might need or want, using materials that were available to the average late 19th century household. 576 pages of fine print--probably a bit of a search to separate the wheat from the chaff but still....a few glances reveals a LOT of useful material here.
