It has been determined to show the distribution of the superficial 



deposits of Prussia on the geological maps on a scale of 1 : 25,000 ; but 



before commencing this work a Commission was appointed to examine 



the way in which the surface-geology of Holland had been worked out 



under Dr. Staring, and to discuss the practicability of constructing the 



N. German map on similar principles. F. W. R.

 Theory of Lake-basins. Quart. Journ. Geol. Soc. vol. xxx. pp. 479- 

 489. 

 Though the author is ready to admit that glaciers may have exca- 

 vated some lakelets and tarns, he maintains that none of the great 

 Alpine lakes have been primarily formed, or have undergone any great 

 secondary modification, by glacier-action. He prefers to account for 

 these large and deep basins by irregular movements of upheaval and 

 subsidence along lines athwart the valleys. A. H. G.
