INDEX 
1 iie difficulty of pronouncing correctly many of the names 
in systematical natural history by those who are not readily 
acquainted with the languages frofn which they are generally 
derived, has induced us to accent those which have more than 
two syllables, and divide such as appear to be most liable to 
mistakes of this nature: as in the words i-dn-thi-na^ which has 
properly four syllables, and ba-la-no-i-des , which has five, it is 
common to pronounce the former j an-thi-na, as if it had only 
three syllables, and the latter bi-la-nor-des , as if it had only 
four. The synonyms are in italics.
