  The work is devoted to the investigation of nontrivial behavior of dilute
water-alcohol solutions. The temperature and concentration dependencies of the
contraction for aqueous solutions of ethanol and methanol are analyzed. The
existence of a specific point, the so-called peculiar point, was established.
It is shown that water-alcohol solutions of different types obey the principle
of corresponding states if temperature and volume fraction are used as
principal coordinates. In this case, the concentration of the peculiar point
for different solutions is close to x_{\nu}=0.28. Several predictions are made.
