graduate school of cnjjiiioerin<^ research 

 incliulinij' two research laboratories, one 

 for physical chemistry under the charge 

 of Professor A. A. Noyes and one for 

 sanitary engineering under the' charge 

 of Professor Wm. T. Sedgwick. The 

 former is to occupy one of the new 

 buildings now being erected beyond the 

 Pierce building, and will consist 

 mainly of a series of small laboratories, 

 with special rooms for weighing, plio- 

 tography, glass-blowing, pure water dis- 

 tillation, etc. There will be next year 

 nine or ten research assistants and as- 

 sociates working under the direction of 

 the professors of the institute, and 

 every facility will be given to advanced 

 students wishing to carry on research 

 work. The Sanitary Research Labo- 

 ratory and Sewage Experiment Sta- 

 tion has leased a building on the line 

 of the largest main sewer, in which 

 have been fitted up laboratories for 

 chemical and bacteriological work, in- 

 cluding a tank and filter house.

death two of the original members of 

 its faculty, whose portraits are here 

 given. Professor John B. Henck was 

 professor of civil engineering from 

 I8G0 to 1881. During this period he 

 devoted himself largely to the work of 

 teaching, but at this time and pre- 

 viously he also carried forward engi- 

 jieering works, the most important 

 probably being the filling in and im- 

 provement of the Back Bay district of 

 Boston. His ' Field Book for Railway 

 Engineers,' published in 1854, and sub- 

 sequently revised, passing through 

 many editions, is a standard work.

 stitute. Professor Henck settled in Cali- 

 fornia and spent his life in retire- 

 ment, dying early in the present year 

 at the age of eighty-eight years. Pro- 

 fessor John D. Runkle was professor of 

 mathematics at the institute from 

 18G5 until last year, when he was 

 made professor emeritus. During this 

 long period he was closely identified 

 with the development of the institute, 

 being always one of the leading mem- 

 bers of the faculty and for a time presi-
