S^ 



Of the simple waters^ about a quarter of a 



pint is a dose^ and of the cordial waters, less th 

 half that quantity. These may be oecasionally 

 given alone ; but they are mostly intended for

 and thus the common forms of medicines, as sent 

 from apothecaries, will be \eryeasy.

 waters, two ounces of one of the compound wa-
