Dear Sir, 
Urgent business has obliged me to be absent from 
home or your second letter and its accompaniments should not 
have remained so long unacknowledged — The examples of each of 
tlio species of Bream were very useful as shewing the differences in 
colour in the same species from different localities and the necessity 
as well as value of attending to characters depending on organic 
structure. Both the Bream were finer in colour than any specimens 
I had hitherto seen — the Roach was also in fine colour, and the 
water of these broads as well as the variety of soil over which they 
extend appear to suit these fish extremely well. The Tench were 
very fine also and very good and I beg you will accept my best 
thanks for them. 
Your information enabling me to improve my account of the 
second Bream which was just going to press I have taken the 
liberty of mentioning your name in reference to the additional 
matter, which I hope you will not disapprove, if, however, you 
have any decided objection to your name being mentioned, pray 
make no ceremony, but let mo know, and I will immediately 
alter it. 
I have but one other little matter to notice. If you will do me 
the favor to send into Norwich on Sunday morning, and I chose 
that day as the one the most certain to be past by you near home, 
your messenger will find at the office to which the Norwich Magnet 
night Coach from Charing Cross runs, a basket containing some 
fish which I will see sent off- on the Saturday (to morrow) 
afternoon — 
I am, Dear Sir 
Yours very truly 
Wm. Yarrell.
