Chemistry and physics, however, meet on common ground in a well-defined branch of science, named physical chemistry, which is primarily concerned with the correlation of physical properties and chemical composition, and, more generally, with the elucidation of natural phenomena on the molecular theory.
But the subject requires elucidation from both chemical and biological points of view.
At the same time it should be remembered that many points await elucidation, and it is unwise to assume conclusions in advance of the evidence.
The applications of anthropogeography to human uses give rise to political and commercial geography, in the elucidation of which all the earlier departments or stages have to be considered, together with historical and other purely human conditions.
He was early attracted by the works of William Blake, whose Songs of Experience he endeavoured to interpret, and of Swedenborg, to the elucidation of whose writings he devoted the best energies of his life.
