This laboratory, under the charge of Dr. H. M. Goodwin, occupies a room measuring 28 by 291/2 feet, and is devoted to photographic work, experiments in electrical conductivity, thermo-chemistry, molecular weight determinations and experiments in chemical dynamics. More recently still, a complete option in electrochemistry has been established, to meet a growing demand.

Still another illustration of the policy of specialization is afforded by the action of the Institute in establishing new courses of study, extending through the entire four years, whenever the need is felt for men trained in a direction not hitherto specially provided for. Thus, in 1888 a new course was established in chemical engineering. The chemical engineer is not primarily a chemist, but a mechanical engineer—one, however, who has given special attention to such problems as the construction of dye works and bleacheries, sugar refineries, soap works, paper and pulp manufactories, fertilizer works, chemical works, and in general all the problems of chemical machinery and manufacturing. That this new course filled a real want was soon made evident. The first class, that of '91, contained seven graduates, while eighty-eight students in all have now been graduated and are for the most part engaged in chemical works.

The physical laboratories of the Institute are now known as the Rogers laboratories. Although they formed perhaps the central feature of President Rogers' plan, financial and other exigencies prevented their being established when the school was opened. In 1869, Prof.
