THE apparatus of which an account is here given was first described in 1895.~ The present description is, in part, a revision of one published in 1897.~ Experience since the latter article was written has led to further improvements in the bomb and accessory apparatus. A nuniber of the improvements have been devised by Mr. Blakeslee, formerly mechanician of Wesleyan University ; others were suggested by Dr. F. G. Benedict, who has had much to do with its use, and by Messrs. Dinsmore and Singleton, of Middletown, Conn., by whom the apparatus is now made. The bomb is a modification of that of Berthelot.8 The latter is most excellent; the only objection to it is its great cost, which is due to the large amount of platinum in the cover and lining. 1 " A New Form of Bomb-Calorimeter," by W. 0.
