Permian sandstone in the Vauxhall delph at Collyhurst the 
till is seen resting upon that rock without any intervening 
bed of sand or gravel; but if any one considered the ex- 
posed position of the rock at the last named place when 
compared with the sheltered locality at St. George’s Col- 
liery, there would be no difficulty in conceiving that a bed 
of sand or gravel might be removed by denuding causes 
in the former, while it would be preserved in the latter.

In my first paper previously referred to ten other instances 
were given of the occurrence of the lower gravel under the 
till in and near Manchester, and in the Additional Notes

found under. 
In the present communication more sections are brought 
forward, the first three of which are from my own obser-

than I had ever previously observed in the neighbourhood 
of Manchester.
