The muscle of the tongue, for vocal utterance, is the most important in our organization. It appears to me, in fact, as if in its tip there were a concentration of all the threads which control our existence; and that it is, therefore, representative of an epitome of our entire being. As all sciences, in a general, though in some instances perhaps somewhat remote, sense, centre in the science of life, so do the controlling elements in our composition centre in the tip of the tongue. If it were possible to analyze it spiritually as well as physically, we would obtain a compendium of knowledge far in advance of any there is in existence in the world at the present time. Still, it must be admitted that this would, to some extent, depend upon _whose_ tongue's tip was submitted to such analyzation. The fact of the tip of the tongue being removed by surgical operation without serious effect upon the mental condition of the individual does not greatly affect my assertion. In that case the concentration must have taken place at the tongue's new tip or end. The tongue's tip, with as infallible correctness as the magnetic needle points towards the north pole, indicates the exact spot whence sounds come, or should come, to appear on the surface in a clear and undefiled manner. The tongue's tip, for English vowel sounds, does not touch any part of the oral cavity. It is constantly changing its position, however, and for every vowel sound, or shade of a vowel sound, points in the direction of or _approaches_ the spot whence a sound comes, or should come. To ascertain such spot with exactitude, it is but necessary to _extend_ the tongue's tip until it reaches the wall of the oral cavity during or, still better, immediately after the utterance of a vocal sound. Upon reaching that spot the tongue may continue in the same position of contact and the sound can still be uttered with entire purity. Change this point of contact, however, but in the least, and such sound will at once cease to come to the surface. Yet, while _apparently_ a sound comes from the direction in which the tip of the tongue points, this is not really the case. In pointing in a given direction, the tongue opens up the channels of the œsophagus and the trachea in a special manner for the proper emission of a given sound, beneath as well as above, and to the left as well as to the right of its radix. In changing the tongue's position but in the least, these channels will open in a different direction, which may then be the proper medium for the emission of another sound, but not for the one under consideration.
