226 THE PARR DESCRIBED. 



fore no artist was asked to make the attempt.] A 

 full-grown parr is the length of a salmon-fry of 

 nine months old ; but its fins are little more than 

 half the size of those of the fry. It is fuller and 

 darker in the body, and in form like that of a well 

 shaped common trout. Its cross-bars, or finger- 

 marks, as they are frequently called, lie closer

The 7th figure is that of the fry at the age

 and below the lateral line. It is a fish of lighter 

 general hue than it was before. 



The 8th engraving on plate No. VIII. approaches 

 more to perfect resemblance, representing the sal- 

 mon-fry at the age of eleven months. It is five 

 inches in length, and the transverse bars are rapidly 

 fading away ; that is, they are becoming eclipsed 

 by the gradual over-spread of a lighter coating. 

 This coating consists of silvery scales, descending 

 in increasing brilliancy from above the lateral line 

 over the transverse bars. The change is fairly 

 represented in the plate. On a salmon- fry of this 

 age, Mr. Young writes, — " The new scales and 

 silver coating begin to appear, the transverse bars
