particles insigniter, maxime and sacli like, are replaced by 

 superlatives. Subifide, raro, nonnunquam, and such like, 

 are better expressed by the syllable sub, prefixed to the ad-

A good description must, in the first place, be complete, 

 that is to say, it must so comprehend the whole of the essen-
