Sulphate of Copper, of fair quality, is procurable in most bazaars; it should be in crystalline masses, of various sizes, of a dark-blue colour, without any light green or whitish powder adherent on the surface; if these exist they should be thoroughly removed previous to the salt being employed medicinally. Or it may be further purified by dissolving in boiling water, filtering, and setting the solution aside to crystallise. In doses of from a quarter grain to two grains it acts as an astringent and tonic; in larger doses (5 to 10 grains) it is a powerful emetic. 110. _In Chronic Diarrhœa and Dysentery_ the following pills are often productive of great benefit. Take finely powdered Sulphate of Copper and Opium, of each 6 grains; thoroughly mix them with a small portion of honey, and divide into twelve pills, of which one should be taken thrice daily. These pills have been found very useful in controlling _Diarrhœa in the advanced stages of Consumption_ (_Phthisis_). _In the Chronic Diarrhœa and Dysentery of Children_, a better form is 2 grains of the Sulphate dissolved in 12 drachms of Omum water; of this the dose is a teaspoonful thrice daily. In all these cases, should benefit not be manifest in a few days, the remedy should be discontinued. 111. _In Diphtheria_ the Sulphate of Copper has been highly spoken of. Of a solution of 5 grains in one ounce of water, a teaspoonful may be given to young children, and repeated every half-hour till it produces vomiting. The same treatment has also been advised in cases of _Croup_. After the occurrence of free vomiting its use should be discontinued. 112. _In Ulcerations of the Mouth_, whether occurring in children or adults, 3 to 5 grains of finely powdered Sulphate, incorporated with half an ounce of honey, is a very useful application. It may be easily applied to the ulcers by the finger. 113. _In the Ophthalmia of Children attended with copious discharge_, a solution of one grain in one ounce of water, applied several times in the day, will often be found serviceable. In obstinate cases the strength may be doubled, but it should never be so strong as to cause pain.
