This monograph of eighty-one pages deals exclusively with urinary calculi. The first nine pages are devoted to a consideration of the history of urinary calculi and of the theories, such as those of Ebstein, Lichtwitz, Kukula, Jores, which have been advanced to explain their formation. Considerable attention is devoted to the chemical composition of the stones and the relation of their chemical composition to gross appearance.
The book deals most satisfactorily and comprehensively with the present status of calculus formation and could be used to advantage as a reference book. Following the text are sixteen colored plates illustrating the color and composition of the various stones.
