original condition, as clear, colourless Carbonate of Lime, though in 
many instances the whole is changed ; the oolitic grains also appear 
to have been changed after deposition. The conclusion drawn by the 
author is that the Oolitic Ironstone was originally Limestone, inter- 
stratihed with ordinary clays containing a large amount of the oxides 
of iron, and also organic matter, which by their mutual reaction, 
gave rise to a solution of bi-carbonate of iron, that this solution 
percolated through the limestone, and removing a large part of the 
Carbonate of Lime by solution, left in its place Carbonate of L'on ; 
and not that the rock was formed as a simple deposit at the bottom 
of the sea." 
Mr. W. Baker, of Sheffield, read a paper on the Purification 
of Lead by Crystallization. 
The next Annual Meeting was held in the Philosophical Hall, 
Leeds, on January 22nd, 1857, and Mr. John Hope Shaw presided. 
Earl FitzwilHam was re-elected President ; and Mr. W. Sykes Ward, 
Honorary Secretary ; Messrs. T. W. Embleton and J. G. Marshall, 
Honorary Curators ; and Messrs. Wm. Alexander, M.D., Halifax, 
Hy. Briggs, Wakefield, H. C. Sorby, Shefiield, and R. D. Baxter, 
Doncaster, were re-appointed local Treasurers and Secretaries. The 
financial statement was of a more satisfactory character than the one 
presented in December 1885, but still left the Society with an 
indebtedness of more than £50. 
The Rev. John Kendrick made some remarks on a hoard of 
Roman coins, numbering between 1200 and 1300, which had been 
discovered in an earthen vessel near Warter, in the East Riding, and 
presented by Lord Londesborough to the museums at York and 
Leeds. The Rev. D. H. Haigh, of Erdington, contributed an erudite 
paper on the crosses discovered at Leeds in 1838, with references for 
comparison with other crosses in the West Riding, and Mr. R. D, 
Chantrell, architect of London, gave a short paper on the same sub- 
ject. Mr. Hy. Denny read a paper on the skull of a dog exhumed 
from the alluvial gravel of Norwich, in 1851. It was found associated 
with the bones of deer and other animals. 
At a subsequent meeting Mr. Thos. Wright, M.A., F.S.A., des-
