amounts to 276. Some writers have even supposed that no 
more than one coin was ever struck from one die. This was 
not the case, and yet perfect correspondence is very rare. 
If their dies were of brass, as there is some reason to sup- 
pose, this would account for frequent change. The Romans, 
though deficient in poetical genius, were very fertile in 
allegory, and hence the variety of symbolical types which we 
find on their coins. 
It is not probable that any of the coins of this period were 
struck in Britain. Those of Valerian, Gallienus, and 
Claudius Gothicus would naturally be struck at Rome ; those 
of the Gallic Tyrants at one of the three mints of Gaul — 
Aries, Lyons, and Treves. Carausius may have coined 
money in Britain, and Constantine is thought to have estab- 
lished a mint in London, but even this is not certain. 
These few remarks may serve to justify what I have before 
said, that the coins of the Nunburnholme find, though neither 
"rich nor rare," are yet capable of affording instruction, 
and reflecting some light on the history of the times. 
ON THE FRAGMENTS OF CROSSES DISCOVERED AT LEEDS 
IN 1838. BY THE REV. DANIEL HENRY HAIGH, OF 
ERDINGTON. 
There can be no doubt as to the age and use of the fragments 
of crosses which were discovered, in the year 1838, in the 
walls of the belfry and clerestory of the old Parish Church of 
Leeds. They were sepulchral memorials, erected, perhaps, 
at different periods from the seventh to the tenth century. 
Of such memorials we find occasional notices in our early 
chronicles. Simeon of Durham, for instance, who wrote 
early in the twelfth century, tells us that Ethelwold, Bishop 
of Lindisfarne, caused a cross to be erected in the cemetery 
of Lindisfarne, and his own name to be engraved upon it;
