INTRODUCTION. xxxr. 



2. For a strengthning plaister, melt two pounds 

 of the common plaister, and add to it half a pound 

 of frankincense, and three ounces of dragon's 

 blood. 



3. For a drawing plaister, melt together yellow 

 vrzz und yellow resin, of each three pounds, and 

 a >}ound of mutton suet. This is used instead of 

 the old melilot plaister to dress blisters ; and the 

 bister piaister itself is made of it, only by adding 

 half a pint of vinegar, and a pound of Spanish 

 flies in powder, to two pounds of it, just as it 

 begins to cool from melting. The quicksilver 

 plaister is thus made ; rub three ounces of quick- 

 silver, with a dram of balsam of sulphur, till it 

 no longer appear in globules, then pour in a pound 

 of the common plaister melted, and mix them well 

 together. 



To close this chapter, I shall add a few wa- 

 ters made without distillation, which are very 

 cheap and very serviceable, and the family shop 

 will then be quite compleat. 



J. Lime water. This is made by pouring gra- 

 dually six quarts of water upon a pound of quick 

 lime ; when it has stood to be clear, it must be 

 poured off. If a pound of lignun vita? wood, an 

 ounce of liquorice root, and half an ounce of sas- 

 safras bark be added to three quarts of lime wa- 

 ter, it is called compound lime water ; and is ex- 

 cellent in foulnesses of the blood. 



2. The blue eye water. This is made by put- 

 ting a dram of sal ammoniac into a pint of lime 

 water, and letting it stand in a brass vessel, till it 

 is of a sky blue colour. 



3. Alum water is made by boiling half an ounce 

 of white vitriol, and the same quantity of alum 

 in a quart ot water, till they are dissolved. 



Thus have we described all the drugs and com-
