Instead of indicating the sounds of the vowels in the Greek and Latin
names given in the notes, we follow the plan of Webster’s Unabridged
Dictionary, giving rules for pronouncing the vowels and consonants. As
the two principal marks (¯ ˘) are in Greek and Latin used differently
from what they are in English, indicating the _quantity_ instead of
_quality_, it will be found less confusing to adopt this method.
