746 PROF. J. We JUDD ON THE NATURE AND RELATIONS OF 
In addition to these are a number of Foraminifera, which were 
submitted by Mr. C. Moore to Prof. T. Rupert Jones, and which 
have not been since reexamined. Among the most interesting of 
these are the curious bodies identified by Mr. Moore and Mr. 
_ Carter as spiny processes of Carpenteria. 
The shells referred by Mr. C. Moore to Nucula planata, Desh., 
and Venus parva, Mant., show but little resemblance to those 
Cretaceous forms, but are too imperfect for exact identification. I 
could find no trace in the collection of any shells which could be 
referred either to Nucula umpressa, Sow., or to Astarte formosa, Sow. 
As what may be a thin representative of Neocomian strata occurs 
at the Richmond well, it became a matter of much interest to 
determine if any beds of that age were found at Meux’s Brewery, 
the more so as fossils of undoubted Neocomian age were asserted 
to have occurred in some of the cores from that place. It has 
sometimes been said that the upper portion of the 64 ft. of rock 
occurring at Meux’s Brewery was of a sandy nature; but this is 
certainly a mistake. From the very top of the series, at a depth of 
1000 ft., which was immediately under the Gault, Mr. C. Moore 
received a specimen of limestone, which on microscopical examina- 
tion is seen to be perfectly oolitic in character. A specimen from 
the depth of 1003 ft. kindly supplied to me by Professor Prestwich 
is also a perfectly oolitic rock of somewhat open texture; and a 
specimen from the depth of 1004 ft. supplied to me by the engineer” 
is one of the most strikingly oolitic rocks I have ever seen. From 
a depth of 1005 ft. Mr. Picking showed me a core of remarkably 
shelly oolite rock containing Trigonia costata, var. pullus, with 
other shells apparently of Jurassic affinities. 
From depths of 1008 and 1012 ft. respectively, Mr. C. Moore 
certainly obtained specimens of an impure and somewhat sandy lime- 
stone. In the case of the specimen from a depth of 1008 ft. the 
insoluble matter amounted to 35 per cent. of the whole rock, and in 
that of the specimen from a depth of 1012 ft. to nearly 17 per cent. 
In both cases the insoluble matter consisted of clay with some sand- 
grains. On careful washing I found these impure limestones yielded 
the same forms of Bryozoa, Echinodermata, and Mollusca as oceur 
in the oolitic limestones above and below them in the series. 
Mr. C. Moore also examined specimens of a “‘ coarse grey marl” 
from depths of 1018, 1024, 1031, 1044, 1050, and 1057 ft. 
respectively. Of these I have been enabled by the kindness of Mr. 
Winwood to study the variety from the depth of 1057 ft. This 
answers perfectly to Mr. Moore’s description, and on washing 
yielded some of the organisms described in his paper, as did also a 
similar specimen from a depth of 1046 ft. 
From many intermediate depths I have obtained specimens of 
perfectly oolitic limestone, and examples of such oolitic limestones 
from depths of 1015, 1022, 1088, 1044, and 1056 ft. have been 
studied in thin sections under. the microscope. It thus becomes 
evident that the whole thickness of 64 ft. of strata found at Meux’s 
Brewery, between the Gault and the Devonian, consisted of oolitic 
oe
