2. Hicerche LagunaH y in charge of G. P. Magrini, L. De 

 Marcht, and T. Gnesotto, under the auspices of the Reale 

 Istituto Veneto di Scienze, Lettere ed Arti. No. 8, Osserva- 

 zioni Mareometriche, Lungo il Utorale e in Laguna (Biennio 

 1906-1907), 50 pp. and 3 'figs. No. 9, Impianti Mareografici 

 Eseguiti) 17 pp. and 4 photos. No. 10, Operazioni Geodetfche 

 Fondamentali per il Bilievo delta Citta e Laguna di Venezia, 

 64 pp., 2 photos, and 1 fig. Venice, 1908. — The reports of the 

 study of the lagoons of Venice (see this Journal, xxi, 407, xxiii, 

 397, xxv, 89) are continued in the three bulletins listed above. 

 The work has now advanced to the point where the velocity, 

 direction of propagation, and physical character of the tidal 

 wave are approximately determined. The records show also a 

 rather uniform wave of translation and a second tide more or 

 less undetermined. The stations of observation have been 

 increased in number and some of them relocated until now there 

 are three in the lagoon of Malamocco, ten in the lagoon of Ven- 

 ice, three in the lagoon of Chioggia, and one each in the lagoon 

 of Murano and at Caorle. 



Of especial assistance to the committee in charge of this inves- 

 tigation has been the action of the city of Venice in undertaking 

 detailed geodetic work in the region about the city, including the 

 establishing of a new base line. The plans include the prepara- 

 tion of a large scale topographical map of the entire district.

3. Beitrage zur Ohemischen Physiologie und Pathologie, 

 herausgegeben von F. Hofmeister. XI Band. Braunschweig, 

 1908 (Fr. Vieweg und Sohn). — This volume concludes the inde- 

 pendent existence of Hofmeister's Beitrage, which henceforth is 

 to be merged with the Biochemische Zeitsckrift, edited by Pro- 

 fessor C. Neuberg of Berlin. Professor Hofmeister will enter 

 the editorial board of the latter journal. The noteworthy con- 

 tributions to physiology contained in the first ten volumes of the 

 Beitrage have been referred to in these columns from year to 

 year. The final volume forms no exception in point of merit. 

 Among the forty or more papers mention may be made particu- 

 larly of E. Friedmann's extensive studies of the katabolism of 

 carboxylic acids in the animal body ; Embden's investigations on 

 the genesis of the acetone bodies ; Wiechowski's observations on 

 the formation of allantoin in metabolism ; Baer and Blum's 

 experiments on acidosis ; and, as usual, numerous contributions 

 on proteins and their derivatives. l. b. m. 



4. Canada's Fertile Northland', edited by Ernest J. Cham- 

 bers. Pp. 139, with 6 tables and 5 maps in pocket. Ottawa, 

 1907 (Government Printing Bureau). — How extensive are the 

 natural resources yet undeveloped in the vast northern area of 

 the Dominion of Canada is well brought out in this volume. 

 The information is given in the form of evidence presented to a 

 Committee of the Senate by a considerable number of persons. 

 This is classified as follows : the territory of Ungava ; the region 

 west of Hudson Bay; the navigability of Hudson Bay; the 

 climate of Canada. A series of large maps accompany the 

 report.
