prudent, I think, to found too mucli upon the similarity of imple- 

 ments now, or recently, in use among divers barbarous nations, and 

 the interesting relics which have been discovered in Dordogne." 

 Mr. Anderson adds his belief '* that under similar circumstances and 

 conditions of things, isolated branches of the human race will arrive, 

 in simple matters of domestic or offensive art, at nearly similar con- 

 clusions, each independently of the other." In this belief Mr. Ander- 

 son is supported by M. Troyon, Dr. Ferdinand Keller, and many 

 other able investigators of pre-historic man in Europe, who have ex- 

 pressed their views in nearly the same words. 



The Plates in the present part, which continue to be executed in 

 the same admirable manner, are Plates xv. and xvi., flint flakes, 

 well selected to illustrate varieties of forms. Plate xvii., four 

 cutting or chopping hatchet-like implements of flint, from Le 

 Moustier, similar in type to those of the old gravel of the Somme, 

 etc. Plate xviii. is devoted to the illustration of flint scrapers and 

 awls. The two remaining plates commence a series of " Sketches 

 on the Vezere," the first being a view of Le Moustier, the second of 

 Les Eyzies, near the Junction of the Beune and the Vezere. They 

 are executed by W. Tipping, Esq., F.S.A.

1. Silliman's American Journal of Science (2nd Series, No. 

 130, p. 96) contains an interesting description of the Glaciers of 

 Alaska, Eussian America, by Mr. William P. Blake. 



"In ascending the Stickeen Kiver" (writes Mr. Blake), "one 

 glacier after another comes into view ; all of them upon the right 

 bank of the stream, and descend from the inner slope of the (Blue) 

 mountain range. There are four large glaciers, and several smaller 

 ones visible within a distance of 60 or 70 miles from the mouth. 

 The first glacier observed, fills a rocky gorge of rapid descent, about 

 two miles from the river, and looks like an enormous cascade. The 

 mountains are greatly eroded by it, for it is overhung by freshly- 

 broken cliffs of rock evidently produced by the action of the glacier.'* 



" The second glacier is much larger and has less inclination. It 

 sweeps grandly out into the valley from an opening between high 

 mountains, from a source that is not visible. It ends at the level of 

 the river in an irregular bluff of ice, a mile and a half, to two miles 

 in length, and about 150 feet high. Two or more terminal moraines 

 protect it from the direct action of the stream. What, at first sight, 

 appeared to be a range of ordinary hills along the river, proved, on 

 landing, to be an ancient terminal moraine, crescent-shaped, and 

 covered with a forest. It extends the full length of the front of the 

 glacier." Within this old moraine is a belt of marsh-land and ponds 

 of water, and then commences the modern moraine, which is desti- 

 tute of vegetation of any kind, and covered with huge blocks of 

 granite, perched in every conceivable position upon the most slender 

 ice-columns, and ready to be hurled down at any moment. The 

 glacier itself seemed rent and torn and faulted by huge chasms and
