Survey, in his memoir on " The Geology of the Country 
around Woodstock, Oxfordshire/' is, however, disposed to 
place this lower. He says, " All these facts tend to prove 
that the ore forms a continuous bed under the area of the 
Great Oolite." We are not in a position, at present, to 
determine this point. Three discoveries, however, of ores of 
iron over large tracts of country which were not a few years 
since thought to contain any mineral treasures of commercial 
value, appear to prove the probability of the extension of 
vast iron ore deposits along the range of the Lias and Oolite 
formations, over tracts of country which have not yet been 
explored with this object. 
The value of our more recent discoveries of iron ore will 
be shown by the following table of the production of iron 
ores in 1859, from those geological formations which have 
been engaging our attention : —

ON THE RECENT DISCOVERIES IN EXCAVATING THE REMAINS 
OF THE ANCIENT ROMAN TOWN OF URICONIUM, (WROXE- 
TER,) NEAR SHREWSBURY. BY THOMAS WRIGHT, ESQ., 
M.A., F.S.A., &C. 
(The following is an Absteact only.) 
The village of Wroxeter is rather more than five miles 
west from Shrewsbury, and occupies a little corner of the 
southern portion of the site of the ancient city of TJriconium, 
on the banks of the river Severn. This place was 
known for centuries to have been the site of an ancient 
city, from the many relics which the plough had turned
