Desbout (Luigi): 'Ragionamento fisico-chirurgico sopra l'effetto della Musica nelle malattie nervose;' Livorno, 1780.--A French translation appeared in the year 1784, in St. Petersburg, entitled: 'Sur l'Effet de la Musique dans les Maladies nerveuses.' Buc'hoz (Pierre Joseph): 'L'Art de connaitre et de designer le pouls par les notes de la Musique, de guerir par son moyen la melancolie, et le Tarentisme qui est une espece de melancolie; accompagne de 198 observations, tirees tant de l'histoire que des annales de la medicine qui constatent l'efficacite de la musique, non seulement sur le corps mais sur l'ame, dans l'etat de sante, ainsi que dans celui de maladie. Ouvrage curieux, utile et interessant; propre a inspirer le gout de cet art, qui est pour nous un vrai present des cieux;' Paris, 1806.--A treatise with a similar title, by F. N. Marquet, appeared at Nancy in the year 1747. Lichtenthal (Peter): 'Der musikalische Arzt; oder, Abhandlung von dem Einflusse der Musik auf den menschlichen Koerper, und von ihrer Anwendung in gewissen Krankheiten,' (The Musical Physician; or, a Treatise on the influence of music upon the human body, and on its application in certain illnesses. Vienna, 1807.)--An Italian translation of this work appeared in Milan in the year 1811. Schneider (Peter Joseph): 'System einer medizinischen Musik; ein unentbehrliches Handbuch fuer Medizin-Beflissene, Vorsteher der Irren-Heilanstalten, praktische Aerzte, und unmusikalische Lehrer verschiedener Disciplinen,' (A System of Medical Music; an indispensable guide for Students of Medicine, Principals of Lunatic Asylums, Practical Physicians, and unmusical teachers of different methods.

To musicians, the most useful books among this class of literature are those which give good advice concerning the preservation of health. F. W. Hunnius, a Doctor of Medicine in Weimar, wrote a book entitled 'Der Arzt fuer Schauspieler und Saenger' (The Physician for Actors and Singers. Weimar, 1798,) which, no doubt, has been useful to many. Another German publication of the kind, in which especial attention is given to the practice of musical instruments in so far as it affects the health, bears the title 'Aerztlicher Rathgeber fuer Musiktreibende' (Medical Adviser for those who cultivate Music) by Karl Sundelin, Berlin, 1832. The author, a Doctor of Medicine in Berlin, wrote his book with the assistance of his brother, who was a professional musician in the orchestra of the King of Prussia. This treatise is so noteworthy that the following account of it will, it is hoped, be of interest to the reflecting musician. Its table of contents is:--
