paiiied with vomiting of food. In this case one part of the solution totwo or three of milk, is usually sufficient” ( United States Dispensatory ).In the dyspepsia of gouty and rheumatic subjects, and which is usuallyaccompanied with a copious secretion of uric acid by the kidneys, Ihave seen lime water serviceable. As a dessicant or astringent, it isuseful as a wash for ulcers attended with excessive secretion. In somescrofulous ulcers in which I have employed it, its power of checkingsecretion has been astonishing. In diarrhoea, when the mucous dischargeis great, and the inflammatory symptoms have subsided, lime water isuseful as an astringent. As an injection in leucorrhcea and gleet -itsometimes succeeds where other remedies have failed. The internal useoflime water has also been serviceable in checking secretion from variousother parts, as from the bronchial membranes, the bladder, &c.

Besides the above, lime water has been employed for various otherpurposes. Thus as an antispasmodic, in hypochondriasis and hysteria,with habitual excessive sensibility of the nervous system, it has beenfound useful by Weickard (Richter’s ausf. Arzneim. iii. 585). It has alsobeen given as an alterative in glandular enlargements and venereal affec-tions, and to promote the deposit of bone earth in diseases accompaniedwith a deficiency of this substance. In skin diseases (tinea capitis,scabies, prurigo, &c.) it has been applied as a wash.

Administration. —From half an ounce tu three or four ounces maybe taken three times a day. As already mentioned, it may be conve-niently administered in combination with milk.

Linimentum Calcis, Pli. Dub. & U. S.; Oleum Lini cum Calce, Ph .Ed. Calcareous soap or oleo-margarate of lime (lime water, linseed orolive oil aa. ecpial parts).—This compound has been celebrated as anapplication to burns and scalds. From being used at the Carron Iron-works, in cases of bums, it is called Carron oil. It is almost invariablyprepared with linseed oil, though in the Dublin Pharmacopoeia olive oilis ordered. Turpentine may be sometimes advantageously added to it.

Cal'cii Chlo'ridum. — Chlo'ride of Cal'cium .

History. —This salt, obtained in the decomposition of sal ammoniacby lime, was known, according to Dulk {Die Preuss. Pharm. iibersetst,&c. ii. 293) in the fifteenth century to the two Hollands, who called itfixed sal ammoniac (sal ammoniacum fixum ). Its composition was notunderstood until the eighteenth century, when it was ascertained byBergman, Kirwan, and Wenzel. It is commonly termed muriate oflime.

Natural Historv. —It is found, in small quantity, in sea and manymineral and well waters. It has also been detected, in a few instances,in vegetables: thus Pallas recognised it in the root of Aconitum Lycoc-tonum.

Preparation. —It is readily prepared by dissolving carbonate of limein hydrochloric acid. The proportions ordered in the London Pharma-copoeia are, five ounces of chalk, half a pint of hydrochloric acid, andthe like quantity of water. When the effervescence has finished, thefiltered solution is ordered to be evaporated to dryness, and the residue
