AN EARLY WORK ON BIRD-MIGRA TION.

the Moon will not be allowed, some other Place must be found 

 out for them." 



With regard to the authorship of the work, in Tonkin's 

 edition of Carew's 1 Survey of Cornwall' (p. 83), it is attributed 

 to the Hon. Francis Koberts, though on what authority I have 

 been unable to ascertain. The work was known to John Legg, 

 author of ' A Discourse on the Emigration of British Birds,' as 

 is shown by Legg's criticism of it on pp. 12, 13 of the ' Emigra- 

 tion,' and by some remarks upon the Woodcock, borrowed (with- 

 out acknowledgment) by Legg. In the earlier work these 

 remarks occur on p. 25 ; in Legg's book on p. 35. 



The views expressed in this tract may seem ridiculous in our 

 day, but it may be suspected that they are not more so than 

 some of the ideas entertained on the subject at the present time 

 will appear to ornithologists of the future.
