Dr. John H. Brinton has put into practice at his surgical clinic at the Jefferson Medical College a new test for cancer, proposed by Mr. H. J. Stites, of Edinburgh. The method, as given by Dr. Brinton, in the Medical News, October 31, is that which was furnished him by Dr. John Chiene, of the Royal Infirmary of Edinburgh, and reads as follows:
Excise the mamma.
Wash thoroughly in water to remove blood.
Place in a 5 per cent, solution of nitric acid (B. P.) for ten minutes.
Wash in cold water for five minutes.
By the time these procedures are executed the axilla is cleaned out and the vessels tied. The mamma is now examined; the carcinomatous structure appears a dull white, like the eye of a boiled fish, the healthy tissue translucent. When any such reaction is seen additional tissue should be removed at the corresponding point.
