Gladstone on Jar(hne\s Calendar. 



[A Natiiralit?t's Calendar, liept by Sir W. Janliut' from 1 Jauiiary 

 to 31 May, 1829. (Reprinted from Trans. Uiunfr. N, H. Soc, 

 Feb. 1919.)] 



A Calendar^ kept for a I'ew moiitlis of one year, can never, 

 of course, be of any great importance ; tiut we should like 

 to draw attention to Mr. Gladstone's transcription of, and 

 notes on, the manuscript of a great naturalist of the Inst 

 century, as it shows the status and abundance of birds 

 on the West Marches of the Borderland in 1829, compared 

 with the present day. 



Gurnerj on the Black-headed Gull. 



[Breeding- Stations of the Black-headed Gull in the British Isles. 

 By Robert Gurney. (Extract from Trans. Norf. &: Norw. Nat. Soc.

It is especially fitting that this article should be written 

 by a resident in Norfolk^ where the well-known "Gullery^' 

 at Scoulton is situated — no doubt the largest in existence 

 in our islands ; while Mr. Gurney has been most success- 

 ful in gathering records and obtaining full information. 

 Probably he has passed over a few cases where the birds 

 have bred in small numbers for a single season ; but this is, 

 we suppose, intentional, though we think that in an area 

 with which we are well acquainted on the Borders, he 

 should have noted the temporary change of quarters of the 

 Pallinsburn colony to the neighbouring Paston Loch.

[A Geographical Bibliography of British Oruithology from the earliest 

 times to the end of 1918. By W. H. Mullens, H. Kirke Swann, and 

 Rev. F. C. R. Jourdain. Part .3. London : 1920.] 



A third part of this woik, which concludes the County 

 of Middlesex and reaches as far as Surrey, is especially 

 important to residents in the Metropolis. AVe congratulate 

 the joint authors on the fullness of the information given,
