The Bleak is a very abundant fish in many of our rivers, and in 
those of the north of Europe in general. The form is elegant, and 
the colours brilliant : the flesh is in some esteem, but it is chiefly 
taken for the sake of the beautiful silvery scales, which artists make 
t* s e of in the manufactory of artificial pearl.
