480 Correspondence—Mr. Arthur H. Foord. 
north-west, there is a large pit worked for sand and gravel, which 
has apparently escaped attention, or at least description. The beds 
are obviously Glacial, and apparently coeval with the Boulder-clay, 
but the boulders and pebbles are cemented with greensand, and not 
with clay. The stratification is distorted, and discontinuous. The 
greatest depth of the section is about 35 feet, and the beds extend 
further beneath. Beginning from below, the layers are in one part 
as follows: loam, conglomerate of boulders, clay, conglomerate, sand, 
pebbles and half-rounded flints, sand, conglomerate, sandy subsoil ; 
the thickness of each layer being three or four feet. The pebbles 
and fossils are of all ages, but flint, chalk boulders, and hard iron 
sandstone predominate. There are also fragments of lignite; Am- 
monites from the Oolite; Granite, and Igneous rocks. It is just 
possible that the beds have been deposited under the combined action 
of ice and rivers, but the beds in no way resemble the river-gravels 
of the Ouse. A layer of sand 3 or 4 feet thick, and about 25 feet 
in Jength, is absolutely free from pebbles, and is of a fine white 
texture, similar to that used for commercial purposes, and quarried 
from the Lower Greensand in many places. It looks as though it 
had been pushed or transported bodily, without any disturbance from 
the Greensand. 
The conglomerate is extremely hard, and fractures occur across 
the contained pebbles like Hertfordshire pudding-stone. A search 
for flint implements proved, as was expected, futile. 4 
This section thoroughly deserves a visit, and I should be ols 
learn the opinion of geologists about its age and probable_s- 
formation. Vow ay 
P.S.—Mr. Cameron, of H.M. Geological Survey, is of opinion that 
these beds are Middle Glacial.

DISCOVERY OF A CIRRIPEDE IN CANADIAN PALAOZOIC ROCKS. 
Str,—I have just received a communication from my friend Mr. 
Henry M. Ami, M.A., F.G.S8., of the Geological Survey of Canada, 
dated Ottawa, 23rd August, 1888, in which he makes the following 
interesting announcement in a postscript :— 
«Last Saturday afternoon, whilst collecting in the ‘ Siphonotreta ’ 
band [lower part of Utica Formation=Bala Limestone Group, in 
part] along the Rideau River—near the rifle range—I had the good 
fortune to come across what appears to be a fossil Cirripede, allied 
to Turrilepas. The group to which these ancient barnacles belong 
lies still in much obscurity ; Darwin, Woodward, Lindstrom, Hall, 
and Clarke have written on them. JI think this is the first time we 
have found any in Canada in Paleozoic rocks.” 
I have only to add that I expect shortly to receive the specimen 
from Mr. Ami for description.
