the fry iiuu-ked bv tlirin, in their experiments, believing 

 them all to be what they considered the young of the Parr, 

 have been retaken as Grilse, Bull-Trout, Salmon-Trout, 

 and River-Trout. That the Parr is not the young of the 

 Salmon, or indeed of any other of the larger species of 

 Salmonidce, as still considered by some, is sufficiently ob- 

 vious from the circumstance that Parrs by hundreds may 

 be taken in the rivers all the summer, long after the fry 

 of the year of the larger migratory species have gone down 

 to the sea ; and the greater part of those Parrs taken even 

 in autumn do not exceed five inches in length, when no 

 example of the young of the Salmon can be found under 

 sixteen or eighteen inclics, and the young of the Bull- 

 Trout and Salmon-Trout are large in proportion. As has 

 been before stated, the transverse dusky bars from which 

 this fish has obtained the name of Brandling and Fingerling 

 are family marks, borne by all the species of the genus for a 

 time, are obliterated by degrees, and at periods depending 

 on the ultimate size attained by the individual species when 

 adult ; the soonest probably in the Salmon, and certainly the 

 latest in the Parr. 



" Some of the rivers of Scotland being unprotected, arc 

 poached to such an extent that very few Salmon or Salmon- 

 Trout escape the nets or spears of their relentless pursuers ; 

 yet the Parr swarms in shoals." — Slaliatics of Scolland. 



" In the Western Isles there arc streams in Avhich Parrs 

 are common, although Salmon never visit them ; and al- 

 though the Salmon and the Sea-Trout, Salmo IrulUi, fre- 

 quent some of the lakes, yet the Parr has never been seen in 

 these lakes."* 



Dr. Heysham, of Carlisle, devoted particvdar attention 

 to the history of this fish, which is there called Branlin and
