Modern science is coming nearer to understanding this. On the one hand Professor Bose spoke about pulsations and showed that vibrations exist even in the vegetable kingdom, so that they can be recorded in graphic form. On the other hand investigators have demonstrated the forms which different vowels make on a glass plate, so that one sees various designs. The forms of various plants and their leaves can be shown in this way. On a recent visit to Paris I met Professor Frossard, who for years has been investigating the effect of the vibrations of the voice upon different parts of the human body, and has been able to demonstrate scientifically how these effects vary with different vibrations.
