_Mildew in Books_ (Vol. ii., p. 103).--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."
