To Purify Foul Apartments
To one tablespoonful of common salt placed in a tumbler, add a large pinch of manganese, powdered fine. Turn over it a quarter of a wine-glass of strong vitriolic acid. Do this at an interval of a few minutes, four or five times; then place the tumbler on the floor of the room that requires fumigating, and leave it for a day or more, closing all the doors and windows tightly. The vapors formed by it will destroy all the foul odors, and sweeten the most filthy air.

Rye Tooth Powder
Rye contains carbonate of lime, carbonate of magnesia, oxide of iron, manganese, and silica, all suitable for application to the teeth. Therefore, a fine tooth powder is made by burning rye, or rye bread, to ashes, and grinding it to powder by passing the rolling-pin over it. Pass the powder through a sieve, and use.
