Ersom Sant. ‘Sulphate of Magne 
“This salt is found in mineral waters, whence it has been extracted, — 
but it is at present principally prepared by art from the liquor re- 
maining after the crystallization of sea salt from sea water; which 
holds a quantity of muriate of magnesia dissolved. When pure, it — 
forms large, regular crystals. . They are soluble in nearly an equal 
weight of water. Their taste is extremely bitter. — 
This salt is used as a very common purgative, in dose of an ounce 
_ or more, dissolved in a large quantity of water. Though its taste is 
loathsome, it remains better on the stomach than many other cathar- 
~ ties, especially when given in small repeated doses. Itis a mild and 
gentle purgative, operating with considerable efficacy, and with 
safety. It is of a cold nature, however, and apt to have a debilita- _ 
_ ting effect, inducing weakness of the blood, dropsy, &&c. For these 
reasons, I never prescribe it. ee 
_ @lauber’s salt, or sulphate of Soda, possesses qualities similar to

_ dose is required; from half an ounce to an ounce being sufficient.
