These require caution, as they are apt to injure the skin. We have omitted those which contain sulphuret of arsenic (orpiment), as there is danger of its being absorbed, and the object can be accomplished without its use. The powders require to be kept in close bottles or boxes, and no more should be mixed with liquid than is required to be used at once.

1. Mix lime and water to a thick cream, and pass through the mixture 25 or 30 times its volume of sulphuretted hydrogen gas. When the gas escapes, stop the process. The pulpy mass is spread on paper, and applied for 12 or 15 minutes, and then washed off with a sponge and water. The only objection to this is its disgusting smell.

2. Chinese. Quicklime 16 oz., pearlas'h 2 oz., liver of sulphur 2 oz. Reduce to a fine powder, and keep it in a close bottle. Use it as No. 4.

3. Mr. Redwood recommends a strong solution of sulphuret (sulphide) of barium, with sufficient powdered starch to form a paste; to be left on for a few minutes, then scraped off with the back of a knife.

4. Boudet's Depilatory. Crystallized hydrosulphate of soda 3 parts, quicklime in powder 10 parts, starch 10 parts; mix. To be mixed with water, and applied to the skin, and scraped off in 2 or 3 minutes with a wooden knife.
