Part I. Definitions. 



§7. It is assumed that all who read this article seriously 

 are familiar with the parts of the brain referred to, and that 

 they have likewise a " working knowledge " of ancient and 

 modern languages. But space will be saved by the employ- 

 ment of certain terms which are rather linguistic than anatomic, 

 and some of which either are comparatively new, or are here 

 used in new or restricted senses ; these are therefore first briefly 

 defined. The definitions of course apply to the Latin forms of 

 the English words ; the adjectives and other derivatives are 

 self-explanatory. ^ 



§8. Onyni. — From oyu,aa, same as ''''v"/^«, a name. Pro- 

 posed by Coues ('82) in the sense of biologic name. It is 

 seldom needed alone but is the essential element or base (§30) 

 of many derivatives. 



§9. Toponym. — From onyin and tot.uz, place. A term 

 indicating location or direction; e. g. lateral, at the side; laterad, 

 toward the side ; transection, cutting across. 



1 Definitions may be found also in the more recent English and medical 

 dictionaries. Some of the terms are discussed in my articles, '85 and '89.
