2305. To Prevent Mould in Mucilage

2305.    To Prevent Mould in Mucilage. Solutions of gum-arabic are very liable to become mouldy; and while the introduction of creosote, corrosive sublimate, etc., frequently used to remedy this evil, is objectionable on account of the danger of poisoning, according to the "Industrie Blatter," sulphate of quinine is a complete protection against mould, a very small quantity of it being sufficient to prevent gum mucilage from spoiling. It is quite possible that writing ink might be protected, by the same application, from a like difficulty. The use of ammonia for the same purpose is also recommended.
