MASSACHUSETTS INSTITUTE OF TECHNOLOGY. 265 



This laboratory, under the charge of Dr. H. M. Goodwin, occupies a 

 room measuring 28 by 29-£ 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 electro-chemistry has been estab- 

 lished, 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.
