Sir
The chemist is at present absent on leave but on his return & on the arrival of your second bore, he shall go to work upon its contents and upon the sample enclosed in your letter & you shall have the result without delay.
If your angillaceous Iron stone should possess the œconomical qualities of our Welsh Mine it will be a valuable discovery.
I remain Sir yr faithfully
