...using the power rooms of the Jefferson and Cruft buildings for the installation of new generating apparatus supplemental to extensive existing equipment, space was economized, and all sources of mechanical disturbance were kept at a distance from the new research quarters. The 100,000 volt storage battery, one of the most powerful high voltage batteries in this country, has been moved to the basement of the research laboratory. Undergraduate instruction is to be carried on in the Jefferson Laboratory...

...clock Professor Black will give a demonstration and description of apparatus seen in foreign schools. At the conclusion of this, an opportunity will be furnished for the members of the association to inspect some of the interesting features of the new research Laboratory, such as the 100,000 volt storage battery, Professor Lyman's ultra-violet vacuum spectograph, Professor Duane's X-ray spectograph, and Professor Bridgman's high pressure apparatus...
...which delicately indicated that the average atomic weight of the isotopes of tellurium is (new observation) 127.47 instead of 127.5. Dr. Bainbridge is proud that his machine cost him only $2,000 to build. President Compton of M. I. T. announced the immediate construction of a 15,000,000-volt x-ray tube and equipment to operate it. Building a tube strong enough to carry that tremendous energy is no great feat. General Electric's Dr. William David Coolidge built one for 900,000 volts. It is now being used to treat cancer in Manhattan's Memorial Hospital...
Among the features of the extensive equipment of the new laboratory are the 100,000 volt storage battery, the Bridgman high pressure laboratory, spectroscopic equipment, and electric oscillation devices. In the Cruft and Jefferson laboratories the visitors will see the new shops, and the original laboratory of Professor W. C. Sabine, where the science of architectural acoustics had its birth...
