Notes, Reviews and Comments. 121 



Sardeson, F. W. — " The fauna of the Magnesian series. 

 Description of fossils." Bulletin of the Minnesota Academy of 

 Sciences. Paper F., Vol. IV., No. i, pp. 92-105, PI. V and VI, 

 Feb. 28, 1896. In this paper Prof Sardeson has done much to 

 clear the veil of obscurity which lay over the palseontological 

 characters of the " Lower Magnesian " and " Potsdam " forma- 

 tions. The former is treated of in this important paper. 



Chalmers, R. — ''Pleistocene marine shore-lines on the 

 south side of the St. Lawrence Valley." Amer. Jour. Sc. Vol. i, 

 pp. 302-308, New Haven, 1896. In this paper Mr. Chalmers 

 brings together a number of observations which seem to correlate 

 and possibly identify the St. Lawrence Valley beach, which is 

 certainly marine, with the Iroquois beach of other authors, and 

 thus reaches the same conclusion arrived at by Taylor, that the 

 marine terraces of the Lake Champlain district coincide with 

 Iroquois, Chippewa and Huron beaches. 



Weston, T. C. — " Notes on the Geology of JSfeufoundland." 

 Trans., Nova Scotia Institute of Science, Vol. IX, pp. 150-257, 

 Halifax, 1896. This paper contains notes of observations made 

 by Mr. Weston in that island during the summer of 1874. A 

 clear statement of the author's non-belief in the organic origin of 

 " Eozoon Gan'idense" accompanies his notes on the Laurentian 

 System. With reference to the Huronian, the Cambrian and 

 Quebec group of the island, Mr. Weston gives numerous lists 

 of the organic remains comprising species described by the late 

 E. Billings. 



Notes on the Devonian, Carboniferous follow the above and 

 thus bring a number of interesting facts together.
