Now, while a slight degree of impurity or in- molecular weight of the impurity, this value of stability would hardly deet the measured melt- m' would represent about 0.02 to 0.06% (for mo- ing point and heat of fusion to the extent here in lecular weights of 50 to 150) by weight of the cam- question, it is possible to account, on such a basis, phor used. Such contamination or decomposi- for the apparently anomalous molecular freezing tion would hardly be ...
