Excerpt from Course of Experiments in Physical Measurement, Vol. 4 of 4: Appendix for the Use of Teachers

The first requisite for a course in elementary Phys ical Measurement is a well lighted and uniformly heated room, with the ordinary precautions to secure good ventilation. Experience has shown that these advantages cannot practically be obtained in base ments, however suitable the latter may be for certain scientific purposes. The first floor of a building, prop erly supported by brick pillars to prevent vibration, has undoubted advantages for a course of measure ments. The use of iron in construction should be in so far as possible avoided on account of its magnetic influence.
