I want to call especial attention to and reiterate the fact that the exact point whence a sound proceeds, or seems to proceed, can, by extending the tongue's tip, be quite as well (if not better) ascertained, _after_ the utterance of a sound, as _during_ such utterance; that is _immediately_ after the tongue has ceased to vibrate for such sound. The difference in the movements of the tongue for various languages is one of the most interesting observations to be made in connection with these studies. The German language being the exact opposite, the antipode, to the English, after comprehending the movements of the tongue for the latter, its own movements, that is, the movements of the tongue for German sounds, were not difficult for me to ascertain. It is an anomaly to apply the works of German writers on the voice to the study of the English language, or to that of any other than the German language; or to apply books written from an English standpoint to the study of any language except the English--the movements of the tongue, and, in sympathy therewith, of countless other muscles, being different for every language. Whatever the movements of the tongue are for the _spoken_ language, they are of an inverse order for _song_. I anticipate in making the following statement, namely, that while speech is of an order which is rapid, direct, anterior, exterior, spontaneous, impulsive, and material, song is of an order which is slow, indirect, posterior, interior, premeditated, contemplative, and spiritual. I will also add this: that, _while speech is of the oral cavity, song is of the pharynx_. In making these remarks and others _in anticipation_, I do so intentionally and for a purpose; not so much in expectation that they will be at once and fully understood, as with a view of setting others thinking on these subjects until I can reach them in due course of time; or, if I should _never_ be able to reach them, that the principle, at least, underlying the same, which if the opportunity had been granted me would have been fully sustained, shall not be lost. The reader will notice that I am hurrying over the ground as rapidly as I consistently can, even from my--under the best of circumstances--superficial standpoint, leaving wide gaps to be filled in by others in the course of time. SIMPLE SOUNDS Speaking of sounds in making experiments in connection with the movements of the tongue, it is of the first importance that these sounds should be _simple_ and not _vocal_ or compound. They must be sounds of the same order as we utter in whispering, or such sounds as we are apt to use when learning to speak a foreign tongue. They are the inharmonious sounds of the deaf, and those which distinguish the speech of a foreigner from that of the native-born. The recognition of these sounds as the _negative parts of speech_ has been one of my main accomplishments, and has been of the greatest assistance to me in my investigations.
