Norr.—Mrs. Lewis desires to state that, after the meeting of the 
British Association at Manchester last year, Prof. Carvill Lewis set 
out in company with herself and Dr. H. W. Crosskey, of Birmingham, 
to visit and examine Frankley Hill, in Worcestershire, the only 
alleged deposit of glacial “Till” south of the great Moraine line 
which he had not seen prior to the Manchester meeting. Here an 
excavation was made, under Prof. Lewis’s superintendence, through 
the gravel to a depth of from eight to ten feet; thence the party 
traced the few detached Arenig boulders to the frontier of Wales. 
Prof. Carvill Lewis then said that for the first time in all his 
experience, both in the old and new world, he had found unmistake- 
able evidence of a glacier, between which and the Glacial Epoch 
there was as vast an interval of time as between that and the present 
day. It was the intention of the late Prof. Lewis to make a thorough 
re-examination of all England, lest a similar deposit elsewhere might 
have escaped his notice; but now that his labours have been so 
suddenly brought to a close, Mrs. Lewis thinks this statement should 
be put on record. —H.W.
