2. "On the so-called Wealdcn Beds at Linksficld." By C. Moore, Esq., 
RG.S. 
The author recognized a similarity of appearance between the shales and 
tliin limestone-beds at Linksfield and those of the Bone-bed series (at the base 
of the Lias) at Pylle Hill, near Bristol, at Aust Passage and at Penarth, on 
the Severn, and at the Uphill cutting on the Great Western Railway. The 
author pointed out some close lithological resemblances, and stated that he 
recognized the " white lias," the " Gotham marble," the " bone-bed," and tiie 
gypseous clay-bands of the south in the qiiarry at Linksficld. Ci/prides, 
lExtheruB, remains of lli/bodus, Lepidot/is, Acrodus, and Plesiosaimis, Mytllus, 
Modiola, Unio, and Ci/clas, from the Linksficld beds, were among the pala;onto- 
logical evidences supporting his correlation of the beds in question.

1. "On a Well-section at Bury Cross, near Gosport." By James Pilbrow, 
Esq. In a letter to the Assistant-Secretary. 
This well, wliich was dug to a depth of one hundred and ten, and bored two 
hundred and twenty-one feet deeper, appears not to have penetrated the 
Bracklesham series of sands and clays, many of the characteristic fossils of 
which, obtained from the well, were exhibited by Mr. Pilbrow, together wdth 
specimens of the beds perforated. The yield of water in this well is very 
copious, certamly equal to five hundred thousand gallons at about seventy feet 
from the surface. When not pumped, the water rises to about nine feet from 
tiie surface. 
2. "On the presence of the Loudon Clay in Norfolk, as proved by a boring 
at Yarmouth." By J. Prestwich, Esq., P.G.S. 
In 18-tO Sir E. Lacon and Co. commenced a well, for the supply of water to 
their brewery, and had a shaft dug to the depth of twenty-two feet, and then a 
boring made to the depth of five hundred and ninety-seven feet, entering the 
Chalk, but stopped by massive flints. The work was unsuccessful ; but the 
specimens of the strata were carefully preserved : Mr. Prestwich and Mr. Rose 
lately examined them, and the following is Mr. Prestwich's opinion of the strata 
that they represent : — blown sand and shingle, about fifty feet ; recent estuarme 
deposits (with Odrea eduUs, Carditim edule, Corbula Nucleus, Tellina Balihica, 
T. planata, Cyprina Idaiidica, Pecten opercularis, Mytilus and Balcmus), one 
hundred and twenty feet ; London Clay, three hundred and ten feet ; Wool- 
wich and Reading series, forty-six feet ; Chalk, fifty-seven feet. 
This section is interesting as being illustrative of the estuary and its filling 
up ; and of the extension of London Clay and Lower Tertiary deposits to a 
more northerly point than had previously been ascertained. 
3. " On some Eoraminifera from the Upper Triassic Clays of Chellaston, 
near Derby." By T. Rupert Jones, Esq., E.G.S., and W. K. Parker, Esq., 
M. Micr. Soc. 
Bluish-grey specimens of the mottled clay from the pits at Chellaston, thi'ee 
miles south of Derby, whence the alabaster is obtained, yielded abundance of 
minute Foraminifera, a few Entomostraca ( Cylhere ), some Otolites, and spines 
and plates of small Eeliinoderms, together with fine siliceous sand and pyritous 
granules. Of the Eoraminifera nearly one-half consist of a small variety of 
Rotalia repanda, namely, R. elegans, D'Orb. The next most numerous group 
are the Nodosarince, including varieties of Nodosaria, Denfalina, Marginulina, 
Vaginulina, Planularia, Frondicuhtria, Flcibellina, and Crhtellaria. The genus
