(c) Dr. Dyce Duckworth says toothache may be relieved by holding in the mouth a solution of bicarbonate of soda, say ½ dr. in 1 oz. water.

(d) A correspondent of the Electrician gives the following as an instant remedy for toothache:—With a small piece of zinc and a bit of silver (any silver coin will do), the zinc placed on one side of the afflicted gum, and the silver on the other, by bringing the edges together, the small current of electricity generated, immediately and painlessly stops the toothache.

(e) Equal parts carbolic acid and collodion applied on a pledger of wadding and thrust into the hollow tooth. Apt to cauterise the mouth somewhat. The saliva must not be swallowed.

(f) Anæsthetic in dentistry: 6 dr. pulv. camphor, 1 oz. æther. sulphur. Apply this to the gum surrounding the tooth to be removed, until the gum turns white, when the tooth can be extracted with scarcely any pain.

Warts.—(a) Apply a little nitric acid (aqua fortis) very carefully. Take a small stick—a lucifer match—dip it into the acid, and so apply a tiny drop to the top of the wart. It soon becomes yellow, and in a few days the top can be picked off. Repeated applications in the same way are necessary.

(b) Light a match or taper and apply the flame for a second, till you feel a sting, to the top of each wart, for 3 days in succession, when a watery blister will form round each wart, which you must burst, and throw all the warts away, which will be found to be quite loose, causing no pain; they will never return again, and no trace of them will be left after a short time.

(c) Prof. Unna recommends the continuous application of mercurial ointment containing 5 per cent. arsenic or a plaster containing in each 8 sq. in. 154 gr. arsenic and 77 gr. mercury.

(d) A plaster of black soap, applied each night for a fortnight, according to Vidal, will soften a wart so that it may be scraped off.

(e) Cellier’s treatment is to transfix the principal wart with the point of a pin, the head of which is then to be held in the flame of a candle until the wart is destroyed; it will drop off in a few days. The remaining warts will then usually disappear.

(f) A touch of castor oil (the best) once a day. It is a slow process, but, nevertheless, a sure remedy, and painless. Choose night time just before going to bed, to rub in well a little castor-oil, and then take a cloth or towel and rub any that remains off. Continue it for a month or two, for it needs persevering in. In some cases there will be no alteration for 2 months; but sooner or later they all die away. Some die away and others can be taken off, as if they had lost their roots.
