418 in putting a small quantity of phosphorus into the heads to make them ignite more easily when brought into contact with the phosphorus on the box. This fraud has actually been carried into effect in Northern Germany, and, although nothing of the kind has been discovered in this country, the fact that it may be will probably increase their unpopularity. The safety-match has certainly had time to win its way, as an old variety of it existed in Switzerland at a period when other parts of the world were still occupied with the flint and steel. It has been claimed for these matches that they are better able to resist moisture than other varieties. The reason, however, is not apparent, as the heads are composed of salts, which are affected by water in the manner of all saline substances. It may be stated as a general rule that those matches are safest which require considerable friction for ignition, and which, when lighted, furnish merely heat enough to kindle the splints. The safest, probably, are those in which a considerable part of the compound is formed of sulphur, as it requires more than usual friction to light them. They are also a quiet match, and in lighting do not scatter any part of the head about. But they kindle slowly, and the sulphurous fumes always render them objectionable. They can also be lighted so conveniently by rubbing them on the wall that a great temptation is held out to servants to disfigure the appearance of a room in this way.

About twenty years ago parlor-matches began to be manufactured and have ever since been growing in favor. No sulphur is used in them, and in their freedom from odor, their convenience and rapidity in lighting, they have a decided advantage over all others. Their noisy explosion is occasioned by chlorate of potash, and may be prevented by substituting nitrate of potash. They are said to be superior to the German match, owing, perhaps, to the fact that they are not coated with varnish. They seem to have attained their greatest popularity in the Western and Southern States, and are used pretty generally among the wealthier classes. Swift & Courtney, who have factories in four different cities, manufacture about 1,500 gross of these daily, and state that the demand for them is constantly increasing. They are nearly half again as expensive as the sulphur match, and grocers and retail jobbers are inclined to increase their price. There is, however, but a small difference between the cost of matches with sulphur and those in which stearic acid is used, as much more sulphur is required than stearic acid. They partake of the same danger that attends the employment of the safety-match, for if they are tipped too profusely the burning material will scatter to some distance. They take fire easily if any one happens to step upon them, and require to be guarded carefully where there are children. But the danger from their use is not alarming, and insurance companies make but little distinction in their rates between these and others. It is a mistaken idea that the invention of matches has caused much
