Subject A, Test 1. ratio mean, the percentage inhibition in sweating caused by the treatment, and the 95•o confidence of this figure are given. A combined, overall set of results is also given for each test. The results, in general, confirm that aluminium chlorhydrate functions as an antiperspirant agent, but that the response from individuals is rather variable. Certain subjects such as panellists A, D and H show a consistently high degree of response, usually in the region of 40• or higher, whereas other panellists such as B, C and L, show only minimal response, often insignificant under the conditions of the test. This suggests that the overall results given for each test have only a very limited meaning, in that they predict an overall situation, but give very little indication of the likely response of an individual subject to a treatment. Such combined figures, therefore, should be used with caution. In this case, however, where the panels were basically similar and the pattern of response in each case was similar, it can be concluded that there was an order of response to the three preparations as follows: Treatment II Treatment I Treatment III
