 BIRDS, 



The Bittern near Harrogate.- — A strange bird, which 

 proved to be a Common Bittern, had been seen in the neighbour- 

 hood of Bishop Monkton for some days during the month of 

 January. My informant, a keeper, had seen it several times, 

 but had not shot it because he thought it was a rare bird. How- 

 ever, on the 2oth it was captured by a boy who took it alive. 

 It only lived a day in captivity, the probability being that it 

 had been injured in some way. — 'R. Fortune, Harrogate.

 CORRESPONDENCE, 

 The Dating of Societies' Transactions. 

 To. THE Editors of ' The Naturalist.' 

 Dear Sirs, 



With regard to the criticism as to the date appearing on the 

 cover of vol. XVI., part 2, of the ' Proceedings of the Yorkshire 

 Geological Society' (see 'The Naturalist,' No. 614, p. 68), 

 allow me to state that however ' extremely improbable ' it 

 may seem to you, 1907 is a correct one for this part, inasmuch 

 as it contains the proceedings of the society for that year. 



May I also be allowed to say that although the number was 

 not issued until the second week of 1908, I fail to see how any 

 grievance which an author might have would be lessened, or 

 how the cause of priority would be served by attaching the date I 

 1908 to papers actually read in 1907. 



Yours etc., 



Arthur R. Dwerryhouse, 

 Hon. Editor, Yorks Geol. Soc.
