Excerpt from Physical Laboratory Notes: Massachusetts Institute of Technology

Hese notes are a portion of the directions which have been prepared from time to time during the past ten years as an aid in class instruction at the Rogers Laboratory of Physics of the Massachusetts Institute of Technology. They are now printed (but not published) by the Institute for the convenience of its students. About one-half of the notes up to page' 36 are supplementary to directions gi\ en in Pickering's Physical Manipulation, vol. I., but the greater portion of the remainder is entirely.independent of any text-book.

The treatment of the subjects of Thermometry and heat-measurements is original. The experiments there described have been found, by experience with classes, to be satisfactory both as to accuracy of results and value for training in careful manipulation. Few, if any, existing text-books give an exact statement Of the proper use of the mercurial thermometer with an. Accuracy of to C. Below 1000 C. In View of this fact, and of the necessity of this knowledge in many branches of professional work, it is thought that the section on Thermometry will be of special interest. The omissions in regard to the use of very sensitive thermometers and to measure ments of very high temperature are intentional, these points being considered bevond the mom of this class of laboratory instruction. 'the notes on Elec trionl Measurements are designed rather for students who are beginning a somewhat elaborate course in that subject than for general students. The notes on Photography are by Mr. W. H. Pickering, Instructor in Physics at the Institute.
