the paper is accompanied, is necessary to render the descriptions 
fully intelligible. 
A letter from Sir Henry Bunbury, Bart. to Dr. Somerville, 
MGS. was read, giving an account of the strata pierced through 
in boring to the depth of 270 feet below the surface, at Milden- 
hall, in Suffolk. ‘This boring was made in the hope of raising 
water toa higher level than that of the surface; but though the 
water filled the shaft, it did not rise above it. 
The substances passed through in this trial were the fol- 
lowing :

Among the fragments of fossils brought up by the boring 
machine were pieces of pentacrinite stalks, and fragments hav- 
ing the appearance of pyrites from the green sand. 
A notice respecting the quartz rock of Bromsgrove Lickie, by 
Mr. James Yates, MGS. was read. 
The quartz rock here referred to has been described by the 
Rev. Mr. Buckland, in the fifth volume of the Geological Tran=. 
sactions. The present notice details the characters and local 
positions of a series of specimens presented by the author to the: 
Society. 
The quartz rock passes on one hand into coarse friable lime- 
stone, in which the crystalline structure entirely disappears ; and 
en the other, into a rock composed of minute quartz crystals. 
The specimens illustrate this transition, and it is remarkable, 
that the crystalline varieties contain impressions of shells. In 
sinking a shaft to the depth of 40 or 50 yards on the eastern side 
of the Lower Lickie range, some of the usual beds of the coral 
formation were passed through; and at a considerable depth a 
limestone was found containing shells, which appear to belong 
to the genus anomia, beneath which was the quartz rock also 
containing impressions of shells of the same kind. These facts 
the author considers as sufficient to determine the class to which 
this rock belongs, and to place it decidedly among the transition. 
series of formations. 
The quartz rock of the Lickie is similar to that which occurs 
at the southern extremity of the Malvern Hills, and to the quartz 
grit of the Wrekin described by Mr. Aikin in the first volume
