Doses
 DOSES MUST ALWAYS BE MEASURED.NEVER GUESS 
 AGE: For an adult, suppose the dose to be 1 drachm. Then: 
 Up to 1 year will require 1/12 (or 5 grains)
 Up to 2 year will require 1/8 (or 8 grains)
 Up to 3 year will require 1/6 (or 10 grains)
 Up to 4 year will require 1/4 (or 15 grains)
 Up to 7 year will require 1/3 (or 1 scruples)
 Up to 14 year will require 1/2 (or 1/2 drachm)
 Up to 20 year will require 2/3 (or 2 scruples)
 Above 20, the full dose of 1 drachm
 Above 65, the inverse graduation of the above 
 
 
 Take into consideration: 
 SEX: Women usually require smaller doses than men
 TEMPERAMENT: Stimulants and purgatives more readily affect a cheery, optimistic sort of person than a sluggish, unemotional type of person. The former will require smaller doses.
 HABITS: Those who use stimulants-smokers, those who drink alcohol regularly will require larger doses.
 CLIMATE: Medicines an act differently on the same individuals in summer and winter, or in countries/regions of different climates. In general, the warmer the climate, the smaller the required dose.

 1 grain (gr) 
 1 scruple (ei) = 20 gr 
 1 drachm (dr) = 3 ei or 60gr 
 1 ounce (oz) = 8 dr or 480gr 
 1 pound (lb) = 16oz or 7,000 grains
