XXIII. A Letter to Dr. William Watfon, 
F. R. S. from the Hon. Daines Barrington, 
F. R. S. on fame particular Fijh fou?td in 
Wales. 
Dear Sir, 
Read April 9, NO WING your attention to every 
thing which relates to any branch 
of natural hiftory, I fhall not make apologies for 
fending you an account of the following particulars 
with regard to perch in a pool of Merionethfhire ; 
and trout, which are found in a river of Cardiganfhire. 
The pool is fituated in the parifh of Trawfvynnyd, 
and is called Llyn Raithlyn ; as it does not lie near 
any road, a common traveller cannot hear any thing 
about it, but by very extraordinary acccident. 
Having been informed by JVTr. Garnons of 
Riwgoch, who lives near this pool, that perch were 
frequently caught there, which were crooked near the 
tail, I have, through him, procured fifh of this fort 
at three different times ; as I intended to preferve 
them in fpirits, I have always delired that they fliould 
be of a fmall lize. 
Thefe fifh were all of them moff apparently 
crooked in that part; which appears Rill Rronger 
(as I am informed) in thofe of a larger lize, and 
fome of them have been taken of nearly two 
pounds.
