Mr. Peebles, on complaining, received the following letter : — 
" Mr. A. Peebles. " 47 High Street, Hull : January 12, 1888. 
" Dear Sir, — In reply to yours of yesterday, please refer to the invoice 
sent you September 30 last ye.ir, and you will see they were not sold as 
pure. I never expected any complaint after so long a time has elapsed. 
The lots j ou had on previous occasions were exactly the same quality, and 
I took it for granted you would know what you were ordering — parti- 
cularly as the price (5/. 12.s. Gd. per ton) was too low to expect a better 
quality — for tlie money it was quite as good as could be expected, and I am 
glad to say I have had no complaints from any one else. 
" I shall be glad wheu you are again a buyer to send you a better article 
if you say I am to do so. — Yours respectfully, " J. M. Jackson."
