integrated limestone from the rock above, confirms the correctness 

 of Mr. Evans's suggestion. 



In narrow valleys, however, where the river passes between per- 

 pendicular limestone cliffs, the rise of the waters during heavy rains, 

 (especially if obstructed by fallen trees and other similar debris) 

 would be extremely rapid, and one can readily conceive that in such 

 cases fine sediment might bo washed into caves considerably above 

 ordinary high- water-mark. 



A gentleman engaged upon the Geological Survey in Australia, 

 mentions an interesting fact in illustration of the difference of level 

 in a country where the rain-fall is considerable. At the time of his 

 writing home he was encamped in a dry gully or watercourse, 

 where, at the height of sixty feet above his head, the wreck of last 

 year's floods was still hanging from the roots and branches, and 

 clinging to the rocky walls of the cliff. 



An interesting comparison is instituted between certain of the 

 implements found in the caves of Dordogne, and some now used by 

 the North- American Indians. Much A^aluable information, and 

 many illustrations (communicated by Mr. Alexander C. Anderson, 

 of Vancouver's Island), are added, which tend to explain the uses 

 of many weapons not heretofore understood. Many suggestions are 

 also offered as to the nomadic habits of the aborigines, their methods 

 of hunting, and general mode of life. 



In the last number of the Geological Magazine, for May, p. 599, 

 quoting from M. Gervais' recent work, on the animals found asso- 

 ciated with man in Western Europe, " The Epoch of the Domestic 

 Keindeer" is spoken of. We are glad to find so experienced an 

 authority as Mr. Anderson decidedly opposed to this view. He 

 writes, ''there is nothing to authorise the supposition that they" 

 (the Germani or the Aquitanians) "tamed the Eeindeer for domestic 

 purposes, but only hunted it." It seems very doubtful whether 

 they possessed any domesticated animals, save perhaps the dog. 

 That the horse was wild, like the reindeer, and formed an object of 

 the chase and an article of food, is abundantly proved by the 

 numerous remains met with in some of the French caverns, espe- 

 cially in that of Bruniquel. From the bones of the horse many of 

 their best implements (e.g. needles) were manufactured. 



Much has been said and written of late, in favour of connecting 

 the ancient inhabitants of Gaul with the modern Laps, Fins, and 

 Esquimaux ; probably this has arisen from the theory, that the pre- 

 historic people of the south migrated northwards in quest of the 

 herds of reindeer which by reason of a change in the climate, or, 

 the increase of their enemies, ceased to visit central and southern 

 France as in earlier times. A certain similarity in their weapons dif the 

 chase and other manufactured articles discovered in their retreats has 

 also favoured this view. But Mr. Anderson justly observes that" Any 

 theory, based upon the disappearance of the Eeindeer from southern 

 latitudes, in connexion with the migration northward in remote ages 

 of the past of the Esquimaux and other northern tribes, ought, I 

 submit to be very cautiously entertained." Nor would it be
