The iftaunafov the thing defined is that respecting 

 which every circumstance is collected that can tend 

 to give a proper idea of it ; take, for exaitipl.^, he'ruvaim 

 nmifiky a speaking a?ihnaly as the definition of *' in-' 

 saiin,'^ that is Man; and, in defining, the definition 

 must correspond w?th the thing defined, that is to 

 say, the description with regard to the thing de- 

 scribed must stand in the relation of mmsavjaiu nmt- 

 tahuhck, real correspondence. It is likewise required 

 tha,t the definition should be more perspicuous, that 

 is, more clear and obvious, and for this reason de- 

 fining by a term that is more general than the thing 

 defined is not proper ; such, for example, asthede-- 

 scription of Man by the term animal. Neither is it 

 admissible to define by a term that is less general ; 

 such as the description of animal by the word Man ; 

 because the relation between annual and vian^ is that 

 of Amom Chusoose Ahitluk, and not that of Mussawaut 

 or perfect agreement, which is required ; nor is it al- 

 lowable to define. by means of a thing equally known, 

 or less known than the thing defined, because it is 

 required that the description should correspond, and 

 be at the same time more clear. 



The nature of definition and its requisites being 

 now understood, let it be remembered that defini- 

 tions may all be referred to four ditlerent kinds, viz. 



1 . Huddi Taum or perfect definition. 

 1. Huddi Nauhi<i or imperfect definition. 



3. Resimi Tauni o^ fcrject indication ox designa- 



tion. 



4. Resimi Nauhs or imperfect indication or de- 



signal ion. 



1. If. the definition consist of the nearest genus 



and the nearest difference, then it is a perfect defini- 



. tion, such as Heiivaun Nautik, the definition of man. 



2. If it consist of the lemotc ge/n(s and the nearest
