Simpson knew the value of perchloride in relieving the hemorrhage and discharge of cancer, and French surgeons equally proved it. The liq. ferri fort. is exceedingly serviceable, as shown in a good paper by Dr. Gibb, of Newcastle; he either filled the vagina with a dilute solution for a few minutes, or plugged with tampons, or painted the strong liquor on the affected part, and so far relieved bleeding and pain, and improved the local condition, as to give, at least, a period of comfort (Lancet, ii., 1874, p. 830). I have myself used the same application with excellent results, and my colleague Dr. Potter constantly uses in cancerous cases a plug of lint or cotton wool soaked in a solution of liquor ferri perchlor. fortior and glycerin (equal parts), and firmly pressed against the uterine surface, the vagina being filled with wool soaked in glycerin. Another method is to apply the saturated solution of perchloride to the affected surface on a Playfair's uterine probe wrapped with cotton wool; this is best in cases when the vagina will not tolerate the presence of tampons.

In cancer other than uterine its application is also valued by myself and many observers independently of its power as a haemostatic: it con-stringes and modifies the affected surfaces, inducing a less rapid growth. Iron cannot cure cancer, but the debility and the anaemia dependent upon it may be much relieved by a course of it.
