 to suit particular standard qualities and prices. 



But due allowance being made for all these dif- 

 ferences, though the mode of manipulation, care, 

 skill, and all other circumstances be the same,

 tions, there remains a difference of quality which 

 can only be ascribed to situation, soil, and cultiva- 

 tion, or some natural or accidental difference in 

 the plant. Let us now proceed to examine this 

 subject.
