THE BIRDS OF ESSEX. 



Arrival of the Summer Migrants at Epping, as observed by Henry 

 doubleday, 1828-1845.* 



* The following series of observations (probably the most complete of its kind ever compiled by 

 one observer), upon the arrivals of twenty-five of our commonest .summer migrants at Epping, for 

 eighteen consecutive years, is taken from Henry Doubleday's Letters to Hey.sham (10) and from his 

 published tables in the .Z'ooA?^/^!' (23. 12, 222, 651 and io65). The years 1828-30 are wholly from the Letters. 

 The years 1831-36, 1839-40, 1841 (partly) and 1844 appear in both the Letters and the Zoologist; while 

 the years 1837-38, 1S41 (chiefly), 1S42-43 and 1845 are from the Zoologist alone. When two different dates are 

 given for the same year, the one marked with an asterisk is the published one. I am quite unable to account 

 for so many differences between the two sources of information. 



a " These arrived as usual all at once." 



b "Arrived in great plenty on the 9th of April. I saw more than a dozen males in sight at the 

 same time." 



c " Young birds flew on the loth of May." 



d " Fewer have visited us thi^; summer than in an)- preceding year that I can remembtr." 



e " Earlier than I ever before met with one."
