Six bum treatments A, B. C, D, E, F were tested on six subjects (volunteers). Each subject has six sites on which a burn could be applied for testing (each ann with two below the elbow and one above). A standard bum was administered at each site and the six treatments were arranged so that each treatment occurred once with every subject once in every position. After treatment each bum was covered by a clean gauze; treatment C was a control with clean gauze but without other treatment. The data are the number of hours for a clearly defined degree of partial healing to occur.
