The district covered by the weather report has as far as 

 practicable been that portion of Europe contained between 

 lat. 40° and 60° N., and long. 10° E. to 10° W., which we 

 believe includes the area immediately affecting the arrival of 

 migrants in England and Wales. 



We may perhaps emphasize the fact that the records in 

 the following Table refer solely to fresh arrivals, and not to 

 any inland movements.
