ADYICE. 



I PUBLISH these lectures at present roughly, in the form in which 

 they were delivered, — (necessarily more brief and broken than that 

 w^hich may be permitted when time is not limited.) — because I know 

 that some of their hearers wished to obtain them for immediate 

 reference. Ultimately, I hope, they will be completed in an illus- 

 trated volume, containing at least six lectures, on the Robin, the 

 Swallow, the Chough, the Lark, the Swan, and the Sea-gull. But 

 months pass by me now, like days ; and my work remains only in 

 design. I think it better, therefore, to let the lectures appear sepa- 

 rately, with provisional wood-cuts, afterwards to be bettered, or re- 

 placed by more finished engravings. The illustrated volume, if ever 

 finished, will cost a guinea ; but these separate lectures a shilling, or, 

 if long, one shilling and sixpence each. The guinea's worth will, 

 perhaps, be the cheaper book in the end ; but I shall be glad if some 

 of my hearers felt interest enough in the subject to prevent their 

 waiting for it. 



The modern vulgarization of the word " advertisement " renders, 

 I think, the use of ' advice ' as above, in the sense of the French 

 'avis' (passing into our old English verb 'avise') on the whole, 

 preferable.
