Camphorated Oil

Best oil of Lucca, gum camphor. Pound some gum camphor and fill a wide-necked pint bottle one-third full; fill up with olive oil and set away until the camphor is absorbed. Excellent lotion for sore chest, sore throat, aching limbs, etc.

Earache

There are various ways of treating earache: the most old fashioned are the appliance of a roasted onion, or a hot bag of salt to the ear, and putting in the ear a small piece of cotton wet with camphorated oil, or simple olive-oil with a drop of chloroform; better still, to puff tobacco smoke into the ear. This remedy is very soothing and effective.

Or, take a small wax taper, pare one end quite small, envelop it in a dry linen rag, insert it into the ear; then light the taper. Odd as this remedy may seem, it is wonderfully rapid and effective; it is practised by all Italian sailors and fishermen.

In Kentucky, a cockroach is drowned in whiskey, then wrapped in hot cotton, and applied to the ear.
