1. Chlorate of potash, powdered galls, tannic acid. To be used for a gargle. The powder should be mixed separately with water, and not rubbed all together.

2. Chlorate of potash, and powdered catechu. The combination is intended as a dentifrice. It, however, should not be dispensed alone. If other conbinations are made, the danger is averted.

3. Chlorate of potash, hypophosphite of soda and water. If the salts are rubbed together, they will explode, but if dissolved separately in the water and mixed, no harm results.

4. Chlorate of potash, tannic acid, glycerine and water. If the tannin, chlorate of potash and glycerine are rubbed together, an explosion ensues; but if the acid is first dissolved in the glycerine and the chlorate of potash in the water, and mixed, no harm follows.

5. Chlorate of potash, tincture chlorate of iron, and glycerine, half an ounce of each. This combination, when put together in the above proportions, is very liable to explode.

6. Chlorate of soda 3 ij, sulphuret of antimony gr. xx. This combination, even if gently triturated, is liable to inflame with a crackling noise.

7. Lac sulphur, gr. iij; antimon. sulp. au-rat, gr. ss; zinci valer., gr. ij; potass, chlor., gr. ij. M. This mixture will explode, however carefully prepared.

8. Permanganate of potash, when associated with any readily oxidizable substance, such as glycerine, explodes.

9. Chromic acid, gr. x; glycerine, 3 j. This mixture is liable to explode, unless the glycerine is added to the acid drop by drop.

10. Iodine and ammonia form a very powerful explosive agent when combined, unless some water is introduced into the mixture, which seems to retard the development of nitrogen iodide, upon which the explosive properties de pend.

11. Iodine, 3 ss; liniment camphor, liniment soap, āā. 3 j. M. This combination may explode from the iodine and the ammonia in the liniment coming in contact.

12. Acidi nitrici, acidi muriatici, tincturae nucis vomicae, āā 3 ij. M. May explode after several hours.

13. Acidi nitro-muriatici, 3 j; tincturae car-damomi, 3 ss. M. This combination was the result once of a serious injury.

14. A mixture of equal parts of acetate of sodium and nitrate of potassium, if heated, explodes with great violence. - M. Violette.
