“Additional Notes on the Drift Deposits near Manchester,” 
by E. W. Binney, V.P., F.R.S., F.G.S. 
In my classification of the Drift Deposits of Manchester, 
printed in Yol. VIII. (second series), is given a fourfold 
division of the beds, No. 4, or the lowest under the till, 
being termed Lower Gravel, and described as a bed of sand 
or coarse gravel having the pebbles contained in it, consist- 
ing of the same kind of rocks as those found in deposits 
Nos. 1, 2, and 3, well rounded, sometimes but not always 
occurring under the till or brick clay. 
Professor Hull, F.B.S., in a paper printed in Yol. II. (third 
series) of the Memoirs of the Society, states, “Another modi- 
fication which we found it necessary to make had reference 
to the lower sand (No. 4) underlying the till in Mr. Binney’s 
classification. We have nowhere been able to discover such 
a bed in situ during our examination ; and it is remarkable 
that in the section of the drift which was furnished by Mr. 
Binney as having been proved at St. George’s Colliery, 
Manchester, and where it is stated that this sand and gravel 
(No. 4) is 10ft. 6in. in thickness, there is no appearance 
whatever of it in the neighbouring quarries of Collyhurst, 
where the till may be seen directly reposing on the Permian 
sandstone. I do not however wish to deny that there are 
occasional patches of sand or gravel underlying the lower 
till, because such bands occur in the till itself. My only 
object is to remove this member from the dignity of a dis- 
tinct subdivision of the drift series, at least till there is 
some better evidence of its existence than the reports of 
well sinkers, the elasticity of whose system of nomencla- 
ture is unhappily proverbial.” He then gives his fourfold 
division. In a paper of my own, printed in the same vol. 
as Mr. Hull’s, a list of eleven drift sections is given in which 
the lower gravel (No. 4) appears in ten found in Man- 
chester. 
No doubt, as Mr. Hull states, it is quite true that on the
