Mildew in Books

In reply to B., who inquires for a prevention for *mildew in books*, I send the following receipt, which I have copied from a book containing many others:—"Take a feather dipt in spirits of wine, and lightly wash over the backs and covers. To prevent mould, put a little into writing ink." Another to take *mildew out of linen*.—"Mix powdered starch and soft soap with half the quantity of bay salt; mix it with vinegar, and lay it on both sides with a painter's brush. Then let it lie in the open air till the spots are out."
