PREFACE. VI 1 



suggestions which have been lately offered for the 

 improvement of their Economic Value ; and, that 

 the student may suffer no loss from our thus giving 

 a prominence to the more popular parts of the sub- 

 ject, we, at the close of the treatise, supply a minute 

 and accurate Synopsis of the Ichthyological portion 

 of the British Fauna, brought down to the present 

 time, which will enable him readily to discriminate 

 species, and assist him in his individual investiga- 

 tions. 



The second and concluding Volume of this de- 

 partment is in the Press, and will soon be pub- 

 lished.
