The interest of 80000^li constantly advanced comes to 3^s per stannary weight to be deducted from the price of 3^li 14^s per cwt. And so in proportion for the interest of a greater or lesser summ advanced. And therefore is ever since the first year & half of the present interest the Queen has advanced more or less about 200000^li the interest comes to 7^s 6^d per cwt to be deducted from the present price of 3^li 14^s per cwt, & so leaves 3^li 6^s as an equitable price per cwt including the Coynage Duty: And this without considering the further loss which the Crown will sustain at {the} {illeg} of the contract by the fall of the price of the Tin.

<539v>

Sixteen hundred Tunns of Tin at 3^li 14^s per cwt stannary which including coynage duty amounts to	}	118400. 00. 00
Freight of 1600 Tunns thereof avoir de pois sent to London at 25^s per Tunn	}	2000. 00. 00
Salaries (including 30^li per annum paid to Truro)		2890. 00. 00
Incidents, Post groats, & Letters, about		1350. 00. 00
If there be allowed for losses by enemy sea & accidents & for promoting the exportation about	}	5645. 14. 03
The total expence will be annually		130285. 14. 03

So that the account is about eaven without recconing interest for money advanced.

The interest of every 20000^li advanced at 6 per cent amounts to 9^d per cwt stannary weight. And therefore if after the first years & half of the present contract there has been about 200000^li (more or lesse) advanced, the interest amounts to 7^s 6^d per cwt stannary weight to be deducted out of the price of 3^li. 14^s per cwt. And by this deduction the price becomes 3^li. 6^s. 6^d per cwt stannary weight, including coynage duty.

And in this recconing, the loss which the crown may sustein in the end of the contract by the fall of the price of Tin is not considered.

1600 Tunns cost		118400
Freight to London		2000
Salaries		2890

Post groats, Incidents & Letters about		1350
Losses by enemy sea & accidents & abatements for encouragement of exportation		5000
Interest of 200000 more or less advanced		12000
	Total	141640

Which is 4^li. 8^s. 6^d $\frac{1}{4}$ per cwt stannary weight, whereas 3^li 16 per cwt avoir de pois is but 4. 1. 5 $\frac{1}{8}$ per cwt stannary. So her Majesty loses 7^s. 1^d $\frac{1}{8}$ per cwt stannary besides the loss by the fall of the price in the end of the contract:

1661^Tuns. 16^cwt. 36^{Lw^t} in 1706 cost		122974.
Scobels account for salaries & Incidents at Cornwall		2828
Anstis's for salaries & Incidents at London		5730
Interest of 200000'		12000
Losses by enemy sea & accidents &c		5000
	Total	148532

Which is 4^li. 9^s. 4^d $\frac{1}{2}$ per cwt stannary weight, whereas 3^li 16^s per cwt, avoirdepois is but 4. 1. 5 $\frac{1}{8}$ per cwt stannary. So her Majesty loses 7^s. 11^d $\frac{3}{8}$ per cwt standard.
