Laboratory Manual of Physics and Applied Electricity. Vol. I., arranged

and edited by Professor E. Nichols. (Macmillan ) — This is a junior course, and a comprehensive one. It is well furnished with all the necessary formulas for experiments and tests, and advocates with great thoroughness the use of plenty of exhaustive tests and consistent care in taking observa- tions. The book, we observe, is composite, so that it has no individuality ; but as a manual, of course, it fulfils its purpose admirably.
