Accent and quantity. 



The marks over the generic and specific names have refereno- 

 not only to the syllable which is to be accented, but to the 

 quantity of the vowel in the accented syllable, as either long or 

 short. 



Those syllables over which the single mark is placed have 

 the vowel pronounced long, as in Fra-ga'-ri-a; those over 

 which the double mark is placed, have the vowel pronounced 

 short, as in He-paP'-i-ca ; in the latter case, the stress of voice 

 seems thrown upon the consonant ; the Iwo marks may, there- 

 fore, be considered as indicating that the consonant, as well as 

 vowel, is accented. 



The general rule respecting words of two syllables is simple, 

 and renders it unnecessary to prefix to such words the marks for 

 accent and quantity. 



Words of two syllables always have the accent on l\\e first , 

 if the syllable end with a vowel it is long, as in Cro'-cus ; if it 

 end with a consonant it is short, as in Cac"-tus. 



NOTE It would be well lor the teacher to request the pupil to com- 

 mit to memory the directions for pronouncing the name of plants 

 the signification of the letters and to observe particularly the marks 

 u.?ed to point out accaii and quantity.
