"This flitting therefore by no means amounts to a 

 total and periodical migration over feas, but is no 

 more than what is experienced with regard to feveral 

 birds. 



For example, the Britifh Zoology informs us *, 

 that, at an average, 4000 dozen of larks are fent 

 up from the neighbourhood of Dunftable, to fupply 

 the London markets ; nor do I hear, upon inquiry, 

 that there is any complaint of the numbers decreaf- 

 ing from year to year, notwithstanding this great 

 confumption. 



I Should not fuppofe that 50 dozen of fkylarks 

 are caught in any other county of England ; and it 

 ihould therefore feem that the larks from the more 

 adjacent parts croud in to fapply the vacuum occafion- 

 ed by the London Epicures, which may be the caufe 

 poffibly of a partial migration throughout the whole 

 ifland. 



I begin now to approach to fbmething like a con- 

 clulion of this (I fear) tedious dhTertation : I 

 think, however, that I mould not omit what appears 

 to me at leaft as a demonflration, that one bird, which 

 is commonly fuppofed to migrate acrofs feas, cannot 

 poffibly do lb. 



apples, which it is conceived he can inftantly extract with his 

 very lingular bill. 



Mr. Tunftall, F. R. S. however, at my defire, once placed 

 an apple in the cage of a crofs-bill, which he had kept for fome 

 time in his very valuable and capital collection of live birds : 

 upon examining the appte a fortnight afterwards, it remained 

 untouched*
