comparative ease ; the “ nonpareil” had to be perused 
slowly, but could be made out with certainty. 
The time at which the above experiment was performed was 8.15 p.m., and the 
evening of course bright and cloudless. The moon was full at 7.49 p.m. the following 
evening. The observers were three in number, who ail succeeded in reading the three 
types, and it should perhaps be added, as a quantity affecting the results, that the 
“ eyes" were all comparatively young, being under the age of thirty.

“ On Boulders of Clay from the Drift,” by E. W. Binney, 
F.B.S., F.G.8. 
In making the new railway from Manchester through 
Cheetham Hill to Kadcliffe, a fine section of the drift depo- 
sits has been exposed in the cutting at Moss Bank, south of 
the bridge near Crumpsall, at an elevation of 207 feet above 
the level of the sea. The beds occur in the descending 
order as follows : 
ft. 
1. Clay containing a few pebbles , . . . . 12 
2. Sand with beds of fine gravel 20 
3. Clay containing the boulders of clay exposed. 1 2 
The first-named bed would be termed by Professor Hull, 
F.B.S., upper boulder clay, the second middle sands and 
gravel, and the third probably lower boulder clay. — See his 
paper on the Drift deposits in the neighbourhood of Man- 
chester, published in vol. II. (third series) of the Society’s 
Memoirs. 
In No. 2, which is composed of fine stratified sand parted 
by thin beds of gravel and deposits of drifted coal, are 
found some basin-shaped deposits of gravel about 3 feet 
long and 1 foot 6 inches deep, which not only contain the 
pebbles usually found in the till much rounded, but also
