Washington, D.C., Jan. 13, 1900.
To the Editor:
—Referring to the paragraph relative to Dematteis' observations on the efficacy of mercurials in the treatment of erysipelas (The Journal, January 13, p. 110), I wish to say that for many years I have used mercurial ointments for the treatment of this disease, successfully. I recall one case, about twelve years ago, in which I applied the white precipitate ointment, and it healed the disease so quickly that the patient's friends became alarmed, declaring the doctor had driven the disease in, consequently another medico was substituted to draw it out. I give this fact for the benefit of Dematteis, hoping he may not be subjected to a like experience.Very respectfully,
