Seen in Germany . was called to the presidencyot the institution ; and it was he with his immediatesuccessor, Professor Kohlrausch, now president ofthe institution, who organized the work and first in-dicated the lines of research which it was to attention was given to the details of construc-tion, so that the various buildings and the apparatusshould be perfectly fitted to the purposes of accurateinvestigation. Money was not stinted, and it isprobable that no other institution in the world isso thoroughly equipped. For delicate experimentsin physics, great solidity of construction is the two main buildings were sunk deepin the earth and set on a firm foundation of stoneand asphalt, so that an earthquake would hardly jarthem. An even temperature is another requirementfor delicate experiments, especially in the domain oftemperature. Therefore the walls were built thickand solid. I was shown the method of constructionin the basement of the physical building, first an outer. S=o O 168 Seen in Germany wall eighteen inches thick, pierced with tight-fittingdouble windows, then an air space reaching fromfloor to ceihng and wide enough for a man to walkin, then an inner wall of solid masonry two and one-half feet thick, also fitted with tight double windowsand doors. Still inside of this there are rooms en-closed in masonry walls and having thick glass floorsand ceilings, glass being the best heat insulator. Theserooms are not artificially heated, and yet they can bekept at a temperature that will not vary winter orsummer throughout the year more than two room has its own ventilator to carry off^ stenchesand acid fumes, so that in no case can one experimentinterfere with another. All the larger rooms are sofitted with extra doors, windows, heating radiators, andlighting apparatus that they can be divided into twoor more smaller rooms should extra places be neededfor peculiarly delicate experiments.
