96 On the Ring Money of the Celte. 
history of the proceedings of the illustrious nation, who so abundantly sowed the seed 
of civilization in the world. As we proceed new lights break in upon us, the inves- 
tigation and elucidation of one question opens a vista to our sight into farther mys- 
_ teries, and eventually enables us to force a passage into the remotest penetralia of an- 
tiquity. If I have not deceived myself, I think I see my way still farther, and that I 
shall be able on a future occasion to produce evidence to illustrate the progress of the 
nations of the most remote antiquity, and to throw some light on the channel by which 
civilization poured to the west. 
[ have now the pleasure of laying before you the specimens of the two descriptions 
of manillas alluded to in Sir John Tobin’s letter, which | have since received from that 
gentleman. The price at first cost is as under : 
The copper manilla is £105. per ton. 
The cast iron manilla £22. per ton. 
The copper manilla weighs somewhat more than two and a half ounces avoirdupois, 
or about six to the pound, and would be about twopence each; but they, no doubt, 
pass for much more in Africa, I believe about fourpence. 
The iron manilla weighs rather more than an ounce and a half, and gives ten to 
the pound, or about one farthing each; I believe they pass in Africa for about one 
halfpenny. 
The weight of the ancient Celtic brass manilla found in Monaghan, is somewhat 
more than three ounces avoirdupois. 
As nothing tends so much to the right understanding of the subject as figures of 
the articles in juxta-position, I have placed the wood-cuts of all the different speci- 
mens in one point of view.
