LAVERET. 305 



PHYS. s You mentioned, among the fish 

 for dinner, the laveret : I never heard of this 

 fish before. 



HAL. It is a fish known in England by 

 the name of shelley, or fresh water herring; in 

 Wales, by that ofguinead; in Ireland, by that 

 ofpollan ; and in Scotland, by that of vengis. 

 In colour it is most like a grayling, but with 

 broader and larger scales : it is common in the 

 large lakes of most Alpine countries, and is 

 known at Geneva by the name of ferra ; and 

 I believe that the salmo ceruleus, or wartmann 

 of Bloch, or the gang-^ftsck of the Lake of 

 Constance, from a comparison that I made of 

 it with the ferra, is a variety of the same fish. 

 It sometimes is as large as 2 Ibs. ; and when 

 quite fresh, and well fried or broiled, is an 

 exceedingly good fish, and calvers like a 

 grayling. The laveret of different lakes has 

 appeared to me to vary in the number of the 

 spines in the fins. One, brought me from 

 the lake of Zurich, 13 inches long and 8 

 inches in girth, had 12 spines in the dorsal 

 fin, 15 in the pectoral fins, 11 in the ventral,- 

 13 in the anal, and 18 in the caudal. The
