As examples of the latter s...ubstances the aldehydes and ketones in particular may be instanced, and these are substances which contain oxygen wholly united to carbon. In explanation of the facts, the assumption is made regarding these compounds that, by addition, the group (C = O)" passes into (C O)"" ; that is to say, a diatomic radical becomes a tetratomic one. Later experiments of a very detailed char- acter on the unsaturated acids, by Fittig, have led to the confirmation of the view mentioned above ; 83 that is, they have shown that the facts are best accounted for when blanks, or bivalent carbon atoms, are assumed in some compounds at least.
