LOWER CARBONIFEROUS FOSSILS IN THE COAL-MEASURES.* 
Mr. R. W. Sxipsey has asked by letter if Mr. J. Ward (a note 
from whom appeared in the last No. of the GEoLocicaL MaGazineE, 
p- 234) will be good enough to state if the English discoveries 
made by himself and the Geological Surveyors have been published ; 
and, if so, where and when. He asks also for the description of the 
fossils found, the character of their holding-ground, and that of the 
immediately adjacent strata, as well as the relative position and dis- 
tance which such ground holds to the Millstone-grit, well enough 
known to hold some Carboniferous Limestone forms. 
Mr. JoHN Warb, writing May 9th, states—‘* You will find a 
notice of the discovery of the marine fosils, by Messrs. Hull and 
Green, in the “Trans. Manchester Geological Society,” vol. iii. 
No. 15, Session 1861-62, p. 348. The fossils are also figured and 
deseribed by Mr. Salter in Mr. Hull’s “Memoir of the Country 
around Oldham” (Geological Survey Memoirs). 
‘The fossils I found (Mr. Ward adds) in the Upper Middle Mea- 
sures at Longton were determined by Mr. Salter as Lingula (two 
species), Discites falcatus, Discina nitida, Macrocheilus, Aviculo- 
pecten, Ctenodonta, and others. The bed I found them in will be 
passed through again in a few months, when I hope to add many 
more species to the list.’ 
To the Editor of the GroLrocicaAL MAGAzInE. 
Sir,—In the newspapers it is stated that a cottage has been seen 
to sink wholly into the earth near Tredegar, South Wales, by the 
collapse of some old coal-mine, certainly, it is stated, 100 feet below. 
As this seems to offer some support to Mr. Fisher’s hypothesis 
(GroLocicaL Macazinz, Vol. IL, No. IIL, p. 102) for the formation 
of the Lexden Pit, by the giving way of the Chalk at about 142 
feet below the surface, I think it worth notice.—ENQUIRER.

OBITUARY NOTICE OF HENRY CHRISTY, F.L.S., F.G.S., &c. &e. 
Henry Curisty, born July 26, 1810, was the son of William 
Miller Christy, the inventor of the Penny Receipt-stamp; was a 
partner in the eminent house of Christy and Co. in Gracechurch 
Street, and succeeded his father as a Director of the London Joint- 
Stock Bank. He displayed in commercial matters the same indomi- 
table energy which he afterwards devoted to scientific pursuits. In 
1850 he travelled to the East. His turn of mind was then strongly 
Kthnological, as exhibited by his collection of primitive Eastern 
fabrics. He also brought from Cyprus an extensive collection of 
* Perhaps some of our readers may have to be reminded that in England the 
real Coal-measures (those above the Millstone-grit) are divided into Upper, Mid- 
dle, and Lower; whilst in Scotland the coal-beds associated with the Yoredale 
Series and Mountain-limestone are termed the Lower Coal-measures; and the 
Coal-measures proper are referred to as the Upper Coal-measures.—EpITor.
