[105] Here followed, in the first Edition, some _Observations on Singing_. See page 98 of this book--But most of them are taken out, and will shortly be published by Messrs. Hurst and Robinson, No. 90, Cheapside, as part of the Prefatory matter of "THE ENGLISH MELODIES," selected by the Author of this work, from the Library of Wm. Kitchiner, M. D. [106] "A knowledge how to regulate the alvine evacuation, constitutes much of the prophylactic part of Medicine; hence, how necessary it is to advise those who either wish to preserve good Health, or are in quest of the lost treasure, to attend to this circumstance."--HAMILTON _on Purgatives_, p. 7. "How much it behoves those who have the charge of young people, particularly of the female sex, to impress them with the propriety, nay with the absolute necessity of attention to the regular state of the Bowels; and to put it in their power, by the use of proper means, to guard against constipation; and at the same time to watch over them, lest, through indolence, they neglect a circumstance which, promoting in the gay season of youth, the enjoyment of health and happiness, opposes a sure barrier against the inroads of chlorosis, &c., always a distressing, and sometimes a fatal complaint."--_Ibid._ p. 76. [107] "There are three things which I consider as necessary to the cure of disorder. "_1st_, That the Stomach should thoroughly digest all the food that is put into it. "The patient perceiving the necessity of obtaining this end, becomes attentive to his Diet, and observes the effect which the quantity and quality of his food and medicines have upon his feelings, and the apparent powers of his Stomach. "_2dly_, That the residue of the food should be daily discharged from the Bowels: here, too, the patient, apprised of the design, notes what kind and dose of purgative medicine best effect the intention, and whether it answers better if taken at once, or at intervals. "_3dly_, That the secretion of Bile should be right, both with respect to quantity and quality. In cases wherein the secretion of Bile has been for a long time deficient or faulty, I recommend unirritating and undebilitating doses of Mercury, (_i. e._ pil. hydrarg.) to be taken every second or third night till the stools become of the wet rhubarb colour."--P. 90. "Any kind of Brown, which dilution will not convert into yellow, I should consider as unhealthy."--P. 36. See MR. ABERNETHY'S _Surgical Observations_. [108] "A popular hypothesis is now very prevalent, which attributes nearly all Diseases to a disturbed state of THE LIVER--for which, Mercurial drugs are lavished almost indiscriminately. The folly of expecting to repel this, or any other opinion which is favourable to the natural indolence of mankind, is obvious, especially when it is at the same time upholden by the empirical interests of greedy individuals."--A. CARLISLE _on Old Age_, 2d edit. p. 88.
