side of the Blizzard. Another interesting fact that the 

 author brings out is a cannibalistic tendency amongst young 

 Buzzards in years when food is scarce, and he even states 

 that he has succeeded in photographing the dreadful operation 

 while in progress. 



It is very gratifying also to note that there has been a 

 marked increase of Buzzards in central Wales during the 

 last three or four years, a result described, probably quite 

 accurately, as one of the bye-products of the war. N.F.T.

Ornithology is indebted to Mr. Gladstone for publishing 

 this interesting fragment from the pen of one of our greatest 

 old-time naturalists. The original was lent to him by the 

 late Dr. Harvie-Brown some years ago and presumably 

 now forms part of the latter 's bequest to the Royal Scottish 

 Museum. Sir William was a man of twenty-nine when he 

 wrote his " Callendar," which may well have represented an 

 attempt to follow in the steps of Gilbert White, and it is to 

 be regretted that the effort did not survive a longer period 

 than five months. The diary is arranged in columns contain- 

 ing daily details of the weather, height of barometer and 

 morning and evening temperatures, with such observations 

 on the birds and the appearances of leaves and flowers as 

 he made from day to day. The bird observations, being for 

 so short a period, naturally do not include much of import- 

 ance, but a remarkable feature, that Mr. Gladstone points 

 out, is the paucity of observations and the number of species 

 of the SvlviidcB, clearly indicating in his opinion that these 

 summer visitors have greatly increased in Dumfriesshire in 

 the last ninety years. Another fact that is brought out 

 clearly in the observations is the apparently very short time 

 taken by the Black-headed Gull (L. ridibtmdus) in acquiring 

 its brown hood. Copious notes of explanation, many of local 

 historical interest, by the Editor, add to the value of the 

 reproduction N.F.T.
