8b. A young lady, age 25, got the same dose of gum ammoniac for an affection that had nothing to do with the eyes. She had precisely the same symptoms, almost complete blindness in the evening. She had never experienced anything similar. On leaving off the medicine this symptom was gone next day.
8c. This case got gum ammoniac in pills. He complained of dimness of vision for several successive evening, and also of stars and fiery points before eyes.
8d. Dr. Lodemann related 2 cases where the same symptoms followed the use of ammoniac. (WICHMANN, Hufeland’s Journ, x, 3, 62.) 9. There is a singular effect, by no one to my knowledge hitherto indicated, of the much belauded gums, ammoniacum and galbanum, when taken rather too largely in the d. The sight is affected in a remarkable manner. Towards evening, it seems to many either as if molten and glowing brass were poured out before the eyes; or, if a lamp or fire be present, this is marvellously encircled with shining colours. With others a dense cloud, as if of dust scattered through the air, dims the vision. But after a few hours these phenomena disappear entirely of their own accord. (Burggravii Comm. de aere, aquis et locis urbis Francofurti, 1751, p. 110, quoted by Wichmann.).
Hughes was a great writer and a scholar. He actively cooperated with Dr. T.F. Allen to compile his 'Encyclopedia' and rendered immeasurable aid to Dr. Dudgeon in translating Hahnemann's 'Materia Medica Pura' into English. In 1889 he was appointed an Editor of the 'British Homoeopathic Journal' and continued in that capacity until his demise. In 1876, Dr. Hughes was appointed as the Permanent Secretary of the Organization of the International Congress of Homoeopathy Physicians in Philadelphia. He also presided over the International Congress in London.
