Extract from the JMUmtes, JOHN B. SCOTT, Sec'ry. DISCOURSE. >^EC ) ligaments of the larynx made to accompany with pro- per vibrations. The charm of musick is confessed by all who have heard it. From the reedy pipes of Pan, to the metallic tubes of Handel; from the simple lyre to the compli- cated piano forte; from the dulcet strains of the artless damsel of the cottage, to the high-toned and wide-va- ried song of the tutored and professed performer, there is a correspondence in musical expression, with the sen- sibilities of our nature. Hence Plato places musick in the constitution of his projected republic ; leaders of armies combine it with martial exercises; directors of civic festivals mingle it with the rejoicings of peace; and Zinzendorff and many more devout men, incorpo- rate it with the public rites of religion. Powerful as is the effect of musick, it is excelled by that of language. This is accomplished by the sentiment the tongue conveys. Here the sounds are full of meaning. They are loaded with significancy. They convey ideas from person to person. They carry expression through the trembling air. They are the vehicles of thought. They bear the tone of feeling and of intellect to indefinite distances. The Almighty is represented as communicating his will, in this mode, to man. The words he spoke to the saints and the prophets, have been faithfully re- corded. When that voice resounded, what a meaning was there! In the effusions of the heart, wc address this ex- alted and incomprehensible Being, with our voices. Whether we make confession of our sins, or offer up applications for mercy: whether we praise him for be- ( io ) nefits received, or pray to him for succour in distress; whether we prostrate ourselves unconditionally before him, or ask in this our blind state, a ray of his guiding light; it is usual and it is reverent to give utterance to our emotions in words. All these functions of the voice would be lost in air, unless there was some sense to which they were immediately adapted. This resides in the organ of hearing. Among the correspondences in nature, there is perhaps none more exquisite and admirable, than that subsisting between the throat and the ear. The fitness extends beyond the constitution of the indivi- dual person; it has the nicest relation to other be- ings of the like organization. In the contemplation of this subject, it ought not to escape observation, that sounds may be heard by the ear of the person who utters them. In this manner they may be modulated, harmonized, and rendered pleasant, as well to the speaker, as to the listener. It is likewise a worthy theme of reflection, that in the act of communicating to another by the voice, there is a chance that both parties may enjoy pleasure; but such is the kindness of providence in this particular, that though the passive party may grow drowsy at the tale, the narrator is sure to be delighted with his own performance. There is an association, by means of the nerves, between the organ of hearing and the tongue. Instead of proceeding from their origin, direct and unconnect- ed, to their respective places of destination, these sen- sitive filaments communicate with each other. While the soft portion (portio mollis) of the auditory nerve, spreads itself upon the labyrinth of the internal ear. ( 11 ) and constitutes the immediate seat of hearing, the hard portion (portio dura) of the same nerve, despatches a branch to join a branch of the fifth pair, and to form by their union the (chorda tympani) cord of the drum. This fifth is called the gustatoryJpair, because it sen
