A testimonial for Tannate of Mercury in The British Medical Journal, July 24, 1866, read as follows:  “when acting as house-surgeon at Guy’s Hospital, I treated all cases of syphilis at the out-patient department with this drug, in order to test its efficacy.  An account of my cases appeared in the Medical Times and Gazette for December, 1885.  I found the average dose to be 1.5 grains t.i.d. taken one hour before meals.  This was sufficient, in most cases, to subdue symptoms.  One patient, a flute-player, even at this dose, was unable to blow his flute, on account of sponginess of the gums.  Strong healthy men could take 2 grains.  It is by far the best preparation of mercury for specific treatment.  Yours, etc.  J. Inglis Parsons, M.D., Assistant-Physician to Chelsea Hospital for Women.”
