PRONUNCIATION. In showing the pronunciation the simplest and most easily understood method has been adopted, that of re-writiny the word in a different form. In doing so the same letter or combination of letters is made use of for the same sound, no matter by what letter or letters the sound may be expressed in the principal word. The key by this means is greatly simplified, the reader having only to bear in mind one mark for each sound. Vowels.

By means of chemical symbols, or formulas, the composition of the most complicated substances can be very easily expressed, and that, too, in a very small compass. An abbreviated expression of this kind often gives, in a single line, more information as to details than could be given in many lines of letterpress.
