Solomon gives us another intimation of the weakness of the human body—listlessness of repose, easily awakened. _He shall rise up at the voice of the Bird_. His age, or sickness, is like the wealth of the rich man, it will not suffer him to sleep; in the night he may have some unquiet drowsiness, but the approach of morn, when healthy young people sleep sound, he shall be broad awake, and at the crowing of the cock, or the singing of a Bird, he shall be rising up from his sleepless bed. Hence the saying, The singing of Birds and the sighing of old Men are generally contemporaries—these are as soon weary of their lodgings, through the pains and wakefulness in the night season, as the Birds are for lifting up their pleasant notes. The last remark in this verse is, _The Daughters of Music shall be brought low_. These Daughters are considered by those skilled in Anatomy, to be both active and passive, such as make Music and such as receive Music; the active make a Music themselves, or bear a part in it; the other delights in that of which they have not the least share in making. There are three several kind of organs that do more immediately, yet distinctly and gradually, conduce to the production of vocal Music; the first is the Lungs, which are the proper instruments of our breathing; the second sort of organs that conduce to music, are such as form the Breath into the Voice, or Respiration, the Tongue, the Palate of the Mouth, the Teeth, especially the four Front Teeth, and, lastly, the Lips: these form the sound into a Voice; the others that modulate this Voice into Music, are the cartilaginous parts of the Wind-Pipe; the head of the Wind-Pipe is very small, yet it has thirteen Muscles belonging to it, most of which are framed only for the modulation of the Voice. Some shut the Pipe, some open it, some dilate, some contract it, so that acting severally or jointly, according as there is occasion, they do wonderfully conduce to the variation of sound. This also has got five Cartilages some are moveable, some immoveable, some of one form, others of anther, that they may better contain the air and break the Voice into Melody. This is the Pipe to sing the high praises of God with, and which infinitely excels all the Instruments of Music: these are the active Daughters of Music which are brought low through age; the passive Daughters of Music are the organs of hearing; these are inward and outward; the outward Ear is spread abroad like a net, that it may gather and catch the sound as it rolls about the ocean of the air; the inward ear is a great secret, that no one can possibly understand—all have confessed their ignorance of this great matter; the first part we meet with is a thin strong membrane, which being placed over the Hole of the Ear, transversely, divides between the inward and the outward Ear; within this there are three Cavities, and three little Bones. So likewise there
