view as to the lagoon-origin of the green earthy sands, and an attempt is made to 
assign its real value to such fossil evidence as they furnish. 
With regard to the view lately reiterated by Messrs. Gardner, Keeping, & 
Monckton, as to the possible marine origin of the upper sands, it is shown that the 
evidence is quite compatible with the theory of their marine-estuarine origin, 
while many of the features they present on a closer study can hardly be explained ° 
in any other way. The author, however, agrees with those writers that there is 
no real necessity for postulating any considerable break in time between the two 
series, as has been done by the Geological Survey. The distribution of the pebble- 
beds is discussed, and shown to admit of a rational explanation in accordance with 
the author’s view as to the history of the Bagshot series. The ‘ decalcification’ 
hypothesis of the writers referred to is criticised, and the probable mode of genesis 
of the irony casts found in the Upper Sands pointed out. 
Lastly, the time required for the formation of these few hundred feet of strata, 
as measured by their continental equivalents, is seen to harmcnise with the 
exceedingly slow rate of deposition which a study of the evidence of their physical 
history reveals to us.

3. Suggestions on Sites for Coal-search in the South-Hast of England. 
By W. Wuiraxker, F.R.S., F.G.S. 
The object of the note is to point out that there are sites, favourably placed for 
the search, where much of the work is already done, in borings for water, &c., and 
the following places are noted :— At St. Margarets, near Dover, Gault was reached 
548 feet down; as the Secondary beds thin northward a further depth of 700 or 
800 feet might be enough to show whether or not coal is present. At Chartham, 
near Canterbury, Gault was reached at the depth of 735 feet. At Chatham, a 
boring penetrated Gault to 943 feet, and then entered Oxford Clay for 22 feet, a 
trial on Government land, which ought certainly to be continued, as is further urged 
by the results of the Chattenden boring. Shoreham (Kent), in Lower Greensand at 
475 feet. Bushey (Herts), in Gault at 700 feet. 200 feet more here might yield 
useful results. Loughton—apparently through the Gault at nearly 1,100 feet. 
Coombs, near Stowmarket, in Gault at 895 feet. 
Other borings, that reach to below the Chalk, at Caterham, East Horsley, 
_ Saffron Walden, Norwich, and Holkham, are referred to.
