“ Etudes des Glacitrs” has excited some of our principal geologists and 
others to hunt after moraines, and they instantly ex proofs of red 
glaciers, and of a cap of ice’ over the- whole ‘northern, he : 
the bowlders and scratches on the rocks and beds of gravel pees soa, 
which erst were considered indubitable proofs of diluvial action. As a 
consequence, several memoirs on the former existence of glaciers in Eng- 
land and Scotland were read at the Geological Society, and gave rise to 
many animated discussions. This is now over, and Mr. Owen’s foot- 
marks and labyrinthine tracks are on the ascendant. But we are steadily 
advancing in knowledge. Although Agassiz’s theory, to the extent to 
which he carries it, cannot be admitted, yet gprs: it explains many 
hitherto obscure phenomena.—Dr. Mantel.
