•One ounce of this folulion of magnefiac liver of fulphur, 

 mixt with a quart of pure water free from any ftiptic or acid 

 mixture, makes a medicinal fulphureous water fit for ufe. If 

 an acid be added to it, it decompofes the liver of fulphur, 

 uniting with the magnefia to form a fal catharticus amarus. 

 Fixed air would therefore be an improper addition to this 

 medicinal water. 



A GROWN perfon may take of this medicinal water, at iirft, 

 half a noggin twice in the day ; and gradually increafe the 

 quantity to three noggins in the day. I have not known it to 

 caufe the head-ach in any perfon except myfelf; and I have 

 always been immediately relieved by taking fix grains of camphor 

 and fix drops of ether in honey and water. 



I HAVE had ample experience of the efiicacy of this medi- 

 cinal water in the cure of thofc diforders which are fometimes 

 called the land fcurvy, and fometimes faid to proceed from 

 impurities of the blood ; fuch as eruptions on the head ; the 

 herpes exedens ; a white, dry, fcaly fcruf ; and thofe various 

 infedious eruptions which in Scotland are named the fibbens, 

 and araongft the common people of this country pafs under a 

 variety. of names. 



The itch is alfo efFedually cured by this water. 



It has had remarkably good effeds in the few cafes of 

 fcrofu'a in which I have had opportunity of trying it.
