the analysis of sounds in relation to the organs of speech. The phonograph affords a visible evidence of the nature and divisions of sound; we may be truly said to know what we can manufacture. Artificial languages, such as that of Bishop Wilkins, are chiefly useful in showing what language is not. The study of any foreign language may be made also a study of Comparative Philology. There are several points, such as the nature of irregular verbs, of indeclinable parts of speech, the influence of euphony, the decay or loss of inflections, the elements of syntax, which may be examined as well in the history of our own language as of any other. A few well-selected questions may lead the student at once into the heart of the mystery: such as, Why are the pronouns and the verb of existence generally more irregular than any other parts of speech? Why is the number of words so small in which the sound is an echo of the sense? Why does the meaning of words depart so widely from their etymology? Why do substantives often differ in meaning from the verbs to which they are related, adverbs from adjectives? Why do words differing in origin coalesce in the same sound though retaining their differences of meaning? Why are some verbs impersonal? Why are there only so many parts of speech, and on what principle are they divided? These are a few crucial questions which give us an insight from different points of view into the true nature of language. (6) Thus far we have been endeavouring to strip off from language the false appearances in which grammar and philology, or the love of system generally, have clothed it. We have also sought to indicate the sources of our knowledge of it and the spirit in which we should approach it, we may now proceed to consider some of the principles or natural laws which have created or modified it. i. The first and simplest of all the principles of language, common also to the animals, is imitation. The lion roars, the wolf howls in the solitude of the forest: they are answered by similar cries heard from a distance. The bird, too, mimics the voice of man and makes answer to him. Man tells to man the secret place in which he is hiding himself; he remembers and repeats the sound which he has heard. The love of imitation becomes a passion and an instinct to him. Primitive men learnt to speak from one another, like a child from its mother or nurse. They learnt of course a rudimentary, half-articulate language, the cry or song or speech which was the expression of what we now call human thoughts and feelings. We may still remark how much greater and more natural the exercise of the power is in the use of language than in any other process or action of the human mind.
