that the curator, in the ordinary pursuit of his duties, need never step outside of these rooms. The auditorium, opposite the main entrance in the basement, is a hall 62 feet by 40 feet and 26 feet high. The rising seats number one hundred and fifty three. There are four classrooms, one on each floor, each seating forty-eight. For study, there is a reading room in the basement for students, a department library on the second floor, and a seminar room on the third floor. The library is about 30 feet square and contains books and journals for immediate use, removed from the main college library and placed in care of the department. Special mention should be made of the supply and tap room for hydrogen sulfide. - This room, directly opposite the laboratory for Qualitative Analysis, is constructed as a large hood, with a ventilating system of its own. In one corner is a generator, designed by Professor Doughty of the chemical staff-anapparatus of stoneware, of very moderate cost, so automatic and self-cleaning that (if an experience of about twenty years can be trusted) it need never be opened, except once a year for recharging. Near-by, also, is a carbon dioxide generator, working on the same plan and principle; and against three walls of the room are students' supply taps for each of the generators. The pipes for hydrogen sulfide are of aluminum with rubber connections to hard rubber stopcocks. On the second and third floors are three suites (each comprising office and private laboratory) and four small laboratories, for special work by members of the staff. In planning the building, the staff and the architects have kept constantly in mind that the purpose of this laboratory is the teaching of chemistry in a small college. Of paramount importance to this end is the provision of adequate space so that each class may have its separate quarters while ample room remains for the carrying on of private work by advanced students and members of the department. We trust that this object has been attained in the present structure, and that the Moore Laboratory will continue for many years to come to serve the needs of our students by giving them that fundamental preparation in science which, as educated men, they will be called upon to apply to the problems of modern life.
Says A11 Scientific Work Not Mathematically Exact. The old belief, widely held at the beginning of the recent great industrial development, that all science could be calculated with mathematical exactness no longer holds true, W. A. Shewhart, of the Bell Telephone Laboratories, believes. Scientists now do not expect to make a thing exactly as they want it and will revise their methods to make better use of this new knowledge.-Science Service
