THE MAMMOTH IN SPACE AND TIME. 147 
coast with Mr. Gunn, who still adhered to his opinion that Elephas 
prumgenius was not found in the Forest-bed. He called attention to 
the probable commingling of Indian and African types in the valley 
of the Euphrates, as shown by the Assyrian sculptures. 
Prof. Bory Dawxr1s, in answer to Prof. Owen, said that the sec- 
tion of the deposits near Northwich in which the Mammoth tooth was 
found was made by the engineer who had made the boring and had 
sent him specimens; and he gave reasons for holding that the Boulder- 
clay was not remanié, but the true Lower Boulder-clay. It contains 
numbers of large striated blocks from Cumberland and Scotland, and 
no marine shells. That was the case in the clay he had described, 
which extended from Northwich to Manchester, and had nothing to 
do with that of Cheshire referred to by Prof. Hughes. He did not 
know that there was any important difference between the blocks in 
the Upper and Lower Boulder-clay. He thought that if Prof. 
Leith Adams would examine the teeth in the museums of Florence, 
Bologna, and Lyons, he would find that the narrow-plated Mammoth 
teeth did shade off into wide-plated varieties, and that the species 
was not so definite as he appeared to think. As regarded Cervus 
megaceros, it occurred in Ballybetale bog in peaty mud above the 
clay, and extended up to close below the upper friable peat. The 
elephant of the Crag was probably HZ. meridionalis.
