A lady of 33, sick for six months; the main symptom was progressive aphonia. A specialist diagnosed papillomata of the larynx, and the patient underwent five local operations for their removal in the course of two months without benefit. She then consulted Dr. Noack, of Lyons, who found the cords red and thickened and almost entirely covered with little papillomata, especially in the arytenoid region. The right apex presented some suspicious physical signs. Spongia 1, three times a day, produced an improvement in the general condition and in the local congestion, but none in the papillomata and the aphonia. Thuja 1, three times a day, was now given. Next month there was sensible improvement, and at the end of three months in all of treatment by Thuja the papillomata had entirely disappeared and the voice had completely returned.
