It will be noted that the differences between the limits4 and 10 per cent are very small, and almost within the limitsof experimental errors, and as it was thought possible thatthere mieht be such errors, Lunges density determina-tions at i5°/4 for similar concentrations were calculatedout according to the methods described above ; the resultsare given in Tables V. and VI. The values of the successive differences in the two setsof data are practically identical, and it would follow thatthe initial rapid increase in the value of the solutionvolumes takes place between o and 4 per cent. Previousobservers have called attention to a slight variation ofphysical properties at the latter concentration, but nostress has been laid upon this point, mainly because mostpersons are sceptic as to the existence of hydrates con-taining a large number of water molecules ; further, thecomplex nature of the molecules of liquid water was notrealised. As to the second limit of concentration, namely, 90 t
