Solution of Lime. Aqua Calcis. Lime Water is thus prepared: - Take Slaked Lime 2 oz., Distilled Water 1 gallon. Introduce the Lime into a stoppered bottle containing the Water, and shake well for two or three minutes. After twelve hours the excess of Lime will have subsided, and the clear solution may be drawn off with a siphon as it is required for use, or transferred to a well-stoppered green glass bottle. The process may be repeated with the remaining Lime four or five times, if the Lime be pure and the bottle accurately stoppered.

Med. Prop. and Action. Antacid, lithontriptic, astringent, and resolvent. Milk is the best vehicle for its administration. In large or long-continued doses, it occasions thirst, constipation, and derangement of the digestive organs. It renders the urine alkaline. Unlike other alkalies, it diminishes the action of secreting organs, and hence has been termed astringent. Externally it is applied to ulcers, cutaneous affections, &c.

Offic. Prep. Linimenturn Caleis(Solution of Lime fl. oz. ij.; Olive Oil fl. oz. ij.). An external application in burns.

Dote of Liq. Caleis, fl. oz. ss. - fl. oz. iij. Each fl. oz. j. contains about gr. ss. of Lime.

Incompatible!!. Acids; Acidulous and Metallic Salts; Ammoniacal Salts; Alkaline Carbonates; Borates, and Astringent Vegetable infusions.

609. Therapeutic Uses

In Acidity of the Prim Vi, in Car-dialgia, and in Dyspepsia arising from or connected with Acidity of the Stomach, Lime Water, in doses of fl. oz. iss. - fl. oz. ij., is often speedily and permanently effectual. It is particularly useful in Dyspepsia occurring in persons whose urine shows strong acid reaction, and when vomiting is a prominent symptom. It is best given in milk. Milk with Lime Water has been found of great service as an article of diet in Ulcer of the Stomach.

610. In Diarrha, depending upon Acidity, Lime Water may be given with manifest benefit. In these cases, mucilage is the best vehicle. It is especially of use in the diarrhoea of infants and young children, and is administered with the best effect when purging and acidity result from artificial feeding. A sixth or fourth part of Lime Water may be added to each pint of milk. In Chronic Dysentery, used in the form of enema, it proves useful in some instances. It may also be given by mouth.

611. As A Solvent For Urinary Calculus, Lime Water Was First Employed By

Dr. Whytt, of Edinburgh, in 1743; and subsequently by Drs. Hales, Butler, and Campbell. They confined their experiments chiefly to injecting a weak solution of Lime Water into the bladder, but Dr. Butler, in 1755, also employed it as a drink, and in the form of an enema. If we are to credit their reports, their practice was signally successful, not only affording relief, but in many instances effecting a perfect cure. The practice, however, fell into disuse until the investigation into the claims of Miss Stephen's nostrum for dissolving calculi, when it was discovered that the basis of this much-famed formula was Carbonate of Lime. It does not appear, however, to possess any particular virtues over the other alkalies as a solvent. It is occasionally useful as a palliative, but cannot be regarded as a curative agent. (See Lithontriptics.)

612. In Pruritus Pudendi, an effectual removal of the distressing symptoms is occasionally effected by the topical application of tepid Lime Water, together with perfect rest and light clothing. To prevent Pitting in Small-pox, Dr. J. Bell* recommends the application of cotton wool soaked in Linimentum Aquae Calcis. He speaks highly of its efficacy.
