Upon thefe occafions, I have frequently inquired 
whether there was any fuch notion or tradition 
amongft the mountaineers, with regard to monocular 
fifh, and have found, that it is fuppofed there are 
fuch in a pool called Llyn y Cwn, which indeed I have 
never feen; but, by the beft accounts I can procure, 
it is high up the Glyder mountain, which forms the 
oppofite fide of the vale of Lanberris to Wyddva, 
or the higheft part of Snowden. 
I have, by means of an interpreter, examined fome 
of thefe mountaineers very particularly with regard to 
this point. One of them told me that, though he 
had often heard of thefe monocular fifh, yet he had 
feen two or three taken by an angler in Llyn y Cwn, 
which did not feem to differ from common trout; 
and indeed the fifh of that lake are feldom caught, 
as they are of very difficult accefs, and have no extra- 
ordinary chara&er either for goodnefs or fize. 
Mr Hughes (of Penrhyn in Carnarvonfhire) having 
known that I had a curiofity with regard to thefe ex- 
traordinary fifh, fent me over laft fummer a moun- 
taineer, whole account of them I took down by means 
of an interpreter, and fend you herewith.
