C.B.TICEHURST: WOOD-PIGEON DIPHTHERIA. 245 



sug-g-ested in the other disease would no doubt help to 

 elucidate the mystery. 



[The points raised by Mr. C. B. Ticehurst seem to us 

 to form most fitting* subjects of enquiiy for the readers 

 of British Birds. It is only by the co-operation of 

 observers all over the country that these and similar 

 interesting problems can be solved. We sincerely hope, 

 therefore, that every reader of the Magazine will take the 

 subject up and give the results of his observations, however 

 limited these may have been. With this object, the 

 essential points upon which evidence is required have been 

 embodied in the form of questions in a schedule, which 

 will be found attached inside the cover of this number. 

 The schedule can be easily detached, and should be filled 

 in and posted to the Editors by March 1st. It would also 

 greatly assist the enquiry if correspondents who can 

 procure Wood-Pigeons suffering from either disease would 

 post them, together with details as to the place and date 

 of capture, and the name and address of the sender, to 

 Mr. C. B. Ticehurst, at Gruy's Hospital, London, S.E. —
