Principles of Chemical Engineering

THE work under notice, by three professors in the department of chemical engineering at the Massachusetts Institute of Technology, Boston, is a welcome addition to the literature dealing with the scientific aspects of the subject. It induces serious reflection on the great strides made in America as contrasted with Great Britain in a matter of vital importance to industrial chemical development, and at the same time provides food for thought to a small minority who consider that there is little scope in industry for the trained chemical engineer.Principles of Chemical Engineering.By Prof. W.
