This proportion, however, doss not agree with -the 
weights I have alTigned to the two coins j for if the 
Denarius weighed 6o Troy grains, and 'the Attic 
Drachm 66|, 6650 Denarii Ihould weigh 6000 
Attic Drachms, o-r a Talent; but tliis number of 
Denarii is deficient of 80 Roman Pounds, by juff 10 
Ounces. 
Now, this adjufitnent of the Talent to Roman 
Pounds, w'as probably cccafioned by the Greeks at- 
tempting to impofe light weights upon th$ Romans, 
w'ho finding the Talent to exceed 79 Pounds, might 
take what it wanted of 80 in their own flwour, t.o 
punidi the Greeks for their unfair dealing. Or, the 
flandard the Romans pitched upon for the Euboic 
Talent might be fomewhat over-weight ; and the 
Coin of Lyfimachus above-mentioned, makes this 
conjedture not improbable j for that in the podefTion 
of Mr. Duane weighs 537,6 Troy grains, which di- 
vided by 8 gives a Drachm of 67,2, exadly the 
weight required by this treaty, fuppofing the Dena- 
rius to weigh 60 grains. But the gold coins of Philip 
and Alexander are fo perfect, and fo correctly hzed, 
that their authority is indifputable ; and if the 
mean Drachm of 66| grains derived from them 
were fomewhat too fmall, it cannot be increafed by ^ 
above a quarter of a grain. 
Therefore, I fuppofe the great weight given to the 
Talent by this Treaty,, may arife, partly from too 
heavy a flandard, and partly from .the Romans taking 
the turn of the fcale in their own favour. 
After the Romans became maflcrs of Greece and 
Afia, the Athenians might find it their interefl to 
lower their Drachm to the weight of the Dena- 
rius,
