"Purity" Is There Such A Thing As Pure Gamefowl

Here I go sticking my neck out on this purity subject again. I don't know what pure is, so far as game fowl are concerned, and in all the thousands of articles which have been published by game fowl magazines on this subject I have never seen even an attempt made to define the word purity. The chemist knows what pure oxygen, hydrogen and various other elements are, and exactly what they will do and how they will react when combined with other elements. Exactly the same result will be obtained every time they are combined.. not most of the time or nearly all the time...but identically the same a thousand times out of a thousand.
