The volume contains many interesting articles, technical as well as others, by the pen of members of the Society. One item of information may interest our readers; namely, that the Society now has a membership of 383, of which, however, some are honorary and some corresponding members. Of this latter category twenty-two are residing in foreign countries.

Mr. C. G. Axell, Chief Consulting Engineer of the Commonwealth Edison Co., is serving his second term as president of the Society.
