Excerpt from Tables of Physical and Chemical Constants and Some Mathematical Functions The need for a set of up-to-date English physical and chemical tables of convenient size and moderate price has repeatedly impressed us during our teaching and laboratory experience. We have accordingly attempted in this volume to collect the more reliable and recent determinations of some of the important physical and chemical constants. To increase the utility of the book, we have inserted, in the case of many of the sections, a brief drum! Containing references to such books and original papers as may profitably be consulted. Every effort has been made to keep the material up to date in many cases a full reference to the original paper is given, while, failing such reference, the year of publication is almost always indicated.
