In the preceding report (VI), we have derived an equation representing the temperature dependence of the odor intensity, and, making use of it under some suppositions, we have found, as a first approximation, that, at ordinary temperature and thereabouts, the intensity decreases with the increase in temperature. In the present report, we have re-examined, aiming at a better approximation, the characteristics of some quantities which had been regarded as independent of temperature in the preceding report. The results are as under. (1) Eq. (8) in text, of just the same form as the previous one with the exception of only one numerical coefficient, was obtained by closely following the foregoing procedure, and it was shown that the influence of temperature was smaller than that found previously. (2) On the assumption that the the surface area of olfactory organ might be affected by temperature, Eq. (9) was derived, indicating the possibility of the odor intensity reaching a peak at a definite temperature; reckoning it to be in the region of 25°-30℃ according to literature, the expansion coefficient of the sensory area was found to be of the order of magnitude of (10)^<-2>ll/deg. The soundness of the finding was discussed, taking into account certain available data.
