Hygiene of the Vocal Organs 
A Practical Handbook for Singers and Speakers

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Six weeks after the publication of the second edition of this volume a third was called for, so that it would not appear that much alteration or addition was required. Nevertheless I have thought it desirable to make a’ few slight changes, the princi pal of which consist in placing the anatomy Of the vocal organs and the chapter on the conflicting views on the falsetto register each in a separate appendix at the end of the volume. The large demand for this little work has also led me to add an index, which I trust will be found useful.
