In vital economy, the search-light of science has found the protoplasm which from our present state of knowledge seems to be the first point of contact between elemental matter and the vital force. What secrets of biology remain unknown within the realm of life, only those who live in the future may ever know. In the first condition of vitalised matter we find the evidence of autonomy. Whatever may be the ultimate force which actuates this monad, the manifestations of its presence and the result of its energy are seen externally. Whatever may be the nature of that force which imparts motion to matter, the first impulse of the biod is to secure food or to associate itself with a unit of its own kind. This is perhaps the first act of volition within the sphere of life, the first expression of some internal want, and is the first faint suggestion of a consciousness, however feeble; and I may add with propriety, that it is my opinion that the vital and psychic forces operate in a manner not unlike the electric and chemical forces. They appear to polarise, and in this condition act on matter in harmony with that great law of Nature under which positive repels positive and attracts negative, and vice versa. We shall not attempt to follow the tedious steps of progress from inanimate matter to man, but begin with those intermediate forms which are so far developed as to utter sounds and understand the sounds of others. We will deal only with tangible facts as we find them. From whatever source expression may arise, or at whatever point it may appear, it is prompted by desire or some kindred emotion, either positive or negative.

At the point where we begin to discuss this question there are two distinct modes of expression, either one of which can be used without the other. But I may mention here a cogent fact, that in the lower forms of life the normal mode of expression is by signs with supplemental sounds. In the higher forms, expression is by sounds, and signs are supplemental. And from the lower to the higher forms this transition is in harmony with the development of physical types. It occurs to me that signs were the first form of expression, and that sounds were first used to call attention to the sign made; and by an association of ideas the sounds became a factor of expression, and were used to emphasise signs. As we ascend the scale of life, sounds become more abundant, and signs less significant, and in the middle types they appear to be of nearly equal value, while in the higher tribes of man sounds are the normal mode of expression, and signs or gestures are used to emphasise them; and thus we see that signs and sounds in the development of the faculty of expression have quite changed places. This is consistent with the observed facts within the limits of human speech. There are tribes of mankind whose language is scarcely intelligible among themselves unless accompanied by signs; and it is said of some of the African tribes that their gestures are more eloquent than their speech. It appears to me consistent to believe that speech appears in the animal organism simultaneously with the vocal organs, and that the desire of expression must have preceded this. The condition of the vocal organs depends upon the type of speech which they are used to utter, and the speech depends upon the quality of thought it is intended to express. That type of speech used by the Caucasian race within the space of a few centuries has developed from a vocabulary limited to a few thousand words into the polished languages of modern Europe, comprising new types and tens of thousands of new words, until to-day our own language contains more than two hundred and twenty thousand words, very few of which, however, if any, are entirely new. The phonetic elements on which is built up this huge vocabulary do not very greatly exceed in number those found in the lowest types of human speech in the world. The total number of these sounds does not much exceed two score in the highest forms of human speech; and about half this number can be shown as the vocal products of some species of the lower animals. Some philologists claim that the blending of consonant and vowel sounds is the mark which distinguishes human speech from the sounds uttered by the lower animals. To show how poorly this gigantic superstructure of fossilised science is supported by the facts, I have developed such effects in the phonograph from a basis of sounds purely mechanical, and without the aid of any part of the vocal apparatus of man or animal. The sounds from which I have developed such results were neither vowel nor consonant as those sounds are defined, but simply prolonged musical notes. In another chapter will be found some of the experiments which I have performed with the phonograph in the investigation of sounds of various kinds. If I am allowed to think for myself at all, I am not ready to accept as final some of the dogmas on the theory of sound which have long been held and taught, and many of which remain orthodox for no other reason than that no one has denied them. I am not ready at this point to spring upon the world any new theory of sound, but I am quite ready to refuse to believe some of the tenets set forth in the creeds of philology.

Heresy is the author of progress, and I confess myself a heretic on many of the current doctrines of the science of sounds.
