THE SALMON FAMILY. 225 



In the foregoing figures, No. 1, represents the impregnated 



egg; 



2. The young fish on emerging from the egg — with the 

 umbilical bladder, from which it draws its sustenance for 

 the first month, attached — this little sack of nutriment being 

 absorbed in about that time ; 



3. The young fish after the umbilical bladder has dis- 

 appeared ; 



4. Kepresents its size when three months old. 



5. Eepresents the size at five or six months old. 



Figure 6, on page 227, shows the size at ten or eleven 

 months. It is seldom found larger with the bars or " finger- 

 marks" on it; and has much the appearance of a young 

 Trout. Figure 7, on same page, represents the fish, when a

 course seaward, to return in a few months a beautiful Grilse, 

 weighing as many pounds, as it did ounces when it set out on 

 its first journey to the great deep. 



The first four figures, on page 224, I have had copied by 

 Mr. Fry's permission, from his work on Fish-Breeding ; the 

 remaining figure (No. 5), and those on page 227 (Nos. 6 and 7), 

 are fac similes of those in the "Book of the Salmon." 



A careful observer will have no hesitation in distinguishing 

 the fry of the Salmon from small Trout. The Salmon-fry 

 have scales which are much more perceptible, and easily de-

 single row of red spots ; the eyes are larger and more promi-

There is a fact connected with its change of apparel, not 



mentioned in the "Book of the Salmon," but which Mr. 



Scrope turns to account in proving that the little fish, known 



for a long time as the "Parr," and thought to be of another
