USEFUL PROJECTS.

N. B. I have not found thai the 

 finest, light, white, magnesia, suc- 

 ceeds as well as a dsiker and hea- 

 vier sort. 



The liquid thus racked off, con- 

 tains in solution what may be 

 named a magnesiac liver of sulphur. 



Some powdered nutgaljs bt-ing 

 mixed with this liquid, and after- 

 wards some r-.lum, the water is by 

 their stiptic qualit) rendered inca- 

 pable of holding the magnesiac 

 liver of sulphur in solution : the 

 latter is therefore precipitated, but 

 not decomposed. 



One ounce of this solution of 

 macnesiac liver of sulphur, mixt 

 with a quart of pure water, free 

 from any stiptic or ;>cid mixture, 

 makes a medicinal sulphureous wa- 

 ter fit for use. If an acid be added 

 to it, it decomposes the liver of 

 sulphur, uniting with the magnesia 

 to form a sal catharticiis amaius. — 

 Fixed, air would therefore be an 

 improper additional to this medici- 

 nal water. 



A grown person may take of this 

 medicinal water, at first, half a 

 noggin twice in the day ; and gra- 

 dually increase the quantitv to three 

 noggins in the day. I have not 

 known it tc cause the head-ach in 

 any person except myself; and I 

 have always been imincdiately re- 

 lieved by taking six grains of cam- 

 phor, and six drops of ether in 

 honey and water. 



I have had ample experience of 

 the efficacy of thi-> medicinal water, 

 in the cure of those disorders which 

 are sometimes called tue land scur- 

 vy, and sometimes said to proceed 

 from impurities of the blood ; such 

 as eruptions on the head; the 

 herpes exedens ; a white, dry, .scaly 

 scurf; and those various infectious 

 eruptions, which in Scotland are 



named the sibbens ; and amongst 

 the common p«)ple of this country, 

 pas^ under a variety ot names. 



The itch is also eftectually cured 

 by this waier. 



It has had rernarkably good eiFect 

 in the fe^v cases of scrofula, in 

 which I have had opportunity of 

 trying it. '' 



In every case of worms, in whi6h 

 I tried it, and they have not been 

 few, it has destroyed them ; those 

 particularly called ascarides. In 

 some of those cases, the patients 

 were in a state of high fever when 

 they took this medicine. This is 

 the only case in which I give this 

 water, whilst symptoms of fever are 

 perceivable. 



I have also found this water to be 

 very successful in the cure of the 

 chronic rheumatism. 



1 have thus, my dear sir, noted 

 down the particulars which you 

 wished me to commit to writuig 

 for you, and am 



Your very affectionate 



humble servant,

The method of preparing the 

 medicinal sulphureous water, fronci 

 this strongly impregnated liquor is 

 very simple, beiug as follows, viz. 



Mix oiie ounce of the impreg- 

 nated liquor with twelve our.ces of 

 cold wdter. 



This medicinal water should be 

 used with caution. Two ounces at 

 a lime may be, in general, a pro- 

 per quantity for a person to begin 

 with. 



The strongly impregnated liquor, 

 and the medicinal watt-r prepared 

 from it, may be k "I't a long time 

 unimpaired.
