Two letters, S and O, a sibilant and a vowel, of which no further explanation can be given.
A vowel is like an olian harp; it makes a full and perfect sound of itself.
Meso: middle: as prefix, drops the o when stem begins with a vowel.
No attempt has been made to indicate these differences of vowel sound.
The Thought is simple and massy enough: but where is a Vowel?
