Gentlemen, 



I shall make no apology for requesting your insertion of the fol- 

 lowing reply to some strictures which have lately appeared in a 

 French pui)lication on a part of my ornithological labours. The 

 kindness with which your pages have hitherto been opened to me,

 that we wish to uphold. The views in Natural science Avhich we 

 advance from time to time in our various speculations ought to be

 erroneous ; or the silent retention of our opinions where no ground 

 has been exhibited for censure. Such a mode of reply would 

 exempt ^he public from much of the personal feelings of in- 

 dividuals,— a subject at all times of little interest, — and the 

 cause of science would pursue its due course, without the interrup- 

 tion of extraneous matter. In the present instance, however, I
