It is seenthat in this curve the effect of temperature has been suchas to almost completely blot out the minimum valuein thecurve for 7=32 and in the other cases the minimum is muchless pronounced than in the curves thus far studied. Theeffect of temperature is also to shift the minimum point tothe right, the rainimiAm point being for an alcohol of about65- 70 per cent.

They however increase more rapidly and inthe most dilute solutions pass the values for the mixturegiving us again the minimum point. At 25° there is not the sslightest trace of a minimum point although the values arewell below the mean of the values for the pure solvents.
