The author traces the evolution of intellectual thought in the progress of chemical investigation, recognizing the various points of view of the different ages, giving due credit even to the ancients. It has been necessary to curtail many parts of the History, to lay before the reader in unlimited space enough about each age to illustrate its tone and spirit, the ideals of the workers, the gradual addition of new points of view and of new means of investigation.
