REVIEWS 691
One of the interesting subjects discussed by Dr. Weingart is the dactyloscopic, or finger-print, system of identification of criminals. This system was first introduced into Great Britain and her colonies in 1901. Dresden has recently adopted it, and it is the opinion of the author that its great advantages over the Bertillon system will soon relegate the latter to a secondary or merely auxiliary position.
The development of the fire department and a discussion of its present position, as shown by the municipal exposition, are given by Brandmeister Mittmann.
A valuable discussion of the bookkeeping necessary for a munici- pality which undertakes large business enterprises, by Dr. Kuhfahl, follows.
The presentation of methods and data of the statistical depart- ments, by Dr. Seutemann, shows the importance of such departments in municipal administration. The treatment is hardly adequate in all points, though the article is suggestive.
The second volume is a worthy supplement to the first, containing over eight hundred reproductions of views, plans, sketches, diagrams, and statistical tables and charts from the exposition the major part of them being published here for the first time.
Several studies of German municipal conditions have appeared in this country some more carefully prepared than others ; but here we have an authoritative work by trained men who are students of the practical affairs of city government and all that pertains thereto. Each, dealing with his own department, gives us a presentation of German problems and of the German way of dealing with them. The Dresden exposition gave these specialists an unexcelled oppor- tunity to make comparative studies of material which up to that time was inaccessible or nearly so.
The book is by no means ephemeral because it commemorates an exposition, for it deals with specific, living, important problems.
