The mean weight of the Denarius from all thefe 
pieces is 60,95 grains j therefore, had all of them 
been perfedt, it might have exceeded 61 grains. But 
the mean from the twenty-one that are fo, amounts 
but to 60,92. Either of them comes very near to 
what Eifenfchmid found it by the like method; 
though he rejeded fome pieces for no other reafon but 
becaufe he thought them too light. 
But a mean from pieces fo unequally fized is not 
to be relied on. And it may be queftioned whether 
thole of above 63 grains ever palTed as common coin. 
Greaves, who had examined many hundred Denarii 
Confulares, fays the bell amounted to 62 grains ; but 
had he met with any of 63, or even of 62I, it cannot 
be doubted that he would have mentioned them in 
fupport of his Denarius of 62^ grains from the 
Congius. Therefore the pieces of 63 grains and up- 
ward mull be very uncommon, whereas they make 
above a feventh part of the number in this table. 
Hence I conclude, that the mean derived from this 
table is of very fmall authority. 
But if we take 5040 Troy grains for the weight of 
the Roman Pound, as determined from the Gold 
coins ; the fcruple will weigh 17I grains ; the Con- 
fular Aureus, 126; the Imperial Aureus^ ii2j and 
the Solidus, 70 : all which are probable weights of 
the feveral Coins; and the Confular Denarius of 84 
in the Pound will weigh juft 60 Troy grains. 
And this muft be very near its true ftandard 
v/eight; for were we to add only half a grain to it, the 
Conlular Aureus would exceed 127 grains, which is 
certainly too great a weight for. that coin.
