M. Burette thinks it easy to conceive, that music may be really efficacious in relieving, if not in removing, the pains of sciatica; and that independent of the greater or less skill of the musician. He supposes this may be effected in two different ways: first, by flattering the ear, and diverting the attention; and, secondly, by occasioning oscillations and vibrations of the nerves, which may, perhaps, give motions to the humours, and remove the obstructions which occasion this disorder. In this manner the action of musical sounds upon the fibres of the brain and animal spirits, may sometimes soften and alleviate the sufferings of epileptics and lunatics, and calm even the most violent fits of these two cruel disorders. And if antiquity affords examples of this power, we can oppose to them some of the same kind said to have been effected by music, not of the most exquisite sort. For not only M. Burette, but many modern philosophers, physicians, and anatomists, as well as ancient poets and historians, have believed, that music has the power of affecting, not only the mind, but the nervous system, in such a manner as will give a temporary relief in certain diseases, and, at length, even operate a radical cure. In the Memoirs of the Academy of Sciences for 1707 and 1708, we meet with many accounts of diseases, which, after having resisted and baffled all the most efficacious remedies in common use, had, at length, given way to the soft impressions of harmony. M. de Mairan, in the Memoirs of the same Academy, 1737, reasons upon the medicinal powers of music in the following manner:--"It is from the mechanical and involuntary connexion between the organ of hearing, and the consonances excited in the outward air, joined to the rapid communication of the vibrations of this organ to the whole nervous system, that we owe the cure of spasmodic disorders, and of fevers attended with a delirium and convulsions, of which our Memoirs furnish many examples." The late learned Dr. Branchini, professor of physic at Udine, collected all the passages preserved in ancient authors, relative to the medicinal application of music, by Asclepiades; and it appears from this work that it was used as a remedy by the ancient Egyptians, Hebrews, Greeks, and Romans, not only in acute, but chronical disorders. This writer gives several cases within his own knowledge, in which music has been efficacious; but the consideration as well as the honour of these, more properly belong to _modern_ than to ancient music.
