 * 1851, Walter Hayle Walshe, A Practical Treatise on the Diseases of the Lungs, Blanchard and Lea; Part I, Chapter I, § V, page #138:

 * The whole bearing of this case favours most strongly Laennec’s theory of ægophony. With the single hypothetical exception I have mentioned, the one thing that seemed to regulate it was the presence and quantity of the fluid ; when the effusion was too great in quantity there was no ægophony, when it diminished the ægophony appeared, when it got down to a certain standard the ægophony was at its maximum, and as it subsided the ægophony descended.
 * 1886, Charles Hilton Fagge, The Principles and Practice of Medicine, P. Blakiston, Son & Co.; Volume I, page #876:
 * And, according to Dr. Stone, the cause of ægophony is that the fundamental tone is intercepted in its passage through a layer of pleural exudation, while the overtones are allowed to pass, and, being heard by themselves, give the peculiar character to the sound. In some further experiments he succeeded in imitating ægophony.
 * 1908, E. Feer, with translation by Theodore J. Elterich, in The Diseases of Children, J. B. Lippincott Company; Volume III, page #375:
 * Absolute flatness is found mostly at the lower portion of the left lung, with disappearance of vocal fremitus, marked bronchial breathing, and ægophony, symptoms which, therefore, point to pleurisy with effusion.
