6. Geological Sketches by L. Agassiz. Second series. 230 pp. 

 12mo. Boston, 1876. (James R. Osgood & Co.)— Geological 

 science owes to Agassiz the first distinct announcement of the 

 glacial origin of the northern drift, and also the collection and 

 publication of facts from Europe and North and South America 

 establishing the truth of his theory. This beautifully printed vol-

 Roads of Glen Roy, in Scotland ;" the " Ice"-period in Ana 

 "Glacial phenomena in Maine;" and the "Physical History ol 

 the Valley of the Amazon." They consist of clear and vivid 

 descriptions and reasonings from one who had seen the facts and 

 scenes he describes, and whose mind was large enough to appre- 

 ciate their significance and grandeur. We think thi^t Professor 

 Agassiz has attributed too wide a range to the ice-covering of the 

 Glacial period in making it extend over the tropics. But if not 

 right in this opinion, his chapter, on the valley of the Amazon, 

 will still be read with interest and profit.
