128 SYSTEMATIC POMOLOGY 



The rule of priority as here set forth, how- 

 ever, covers only half the ground. It applies 

 to any case in which one variety has two 

 names. Yet it is not at all uncommon to find 

 one name doing duty for two varieties. It is 

 evident that in such cases the name belongs 

 to that variety upon which it was first publicly 

 bestowed, and the second variety must find 

 another name. This is one of those good 

 rules which work both ways. 



The rules which we have just been dis- 

 cussing are a direct outgrowth of another set 

 of rules proposed to the American Porno- 

 logical Society by Mr. P. Barry in 1867. 

 These rules are very interesting in them- 

 selves, and they throw some light on the de- 

 velopment of the science of nomenclature in 

 its application to American pomology. For 

 these reasons it will be worth while to tran- 

 scribe these rules here : *
