In the chronic stages of urethral inflammation, sulphate of iron forms a good injection. I recommend about 12 gr. with 1/2 oz. of laudanum, in 8 or 10 oz. of water - a little to be used three times a day; another form, recommended by Dr. Ringer, contains 1/2 dr. of the per-chloride tincture, with 1 dr. of laudanum in 1/2 pint water. "It often speedily checks the discharge, and relieves pain on micturition." Baru-del, writing from a large experience, would absolutely restrict the local use of perchloride to chronic cases, but he advocates it internally for all forms of urethritis, acute and chronic (Medico - Chirurgical Review, i., 1859, p. 244). I would not myself recommend its use, even internally, in acute stages, but in the later ones of gonorrhoea, or gleet, full doses of 10 to 15 min. are of real advantage. Pereira recommended the remedy in combination with tincture of cantharides.
