INTRODUCTION. 
No one will lightly attempt a supplement to 
Booth’s Catalogue of his cases who has entered 
fully into the spirit of that Catalogue. Does 
Booth not say in his 1876 Introduction “The few 
notes and facts I have recorded are. solely the 
result of personal observation, and with two other 
exceptions (all noted) not a book of reference has 
been opened.” Look at his notes on the Gannet 
{case 153), the Raven (case 97), the Merganser 
(case 249), and the large Wheatears (case 147) ; or 
again read what he says under the head of Knot 
(case 150), or Pomerine Skua (case 219), the Lesser 
Black-backed Gull (case 217), or Snipe (case 186) ; 
and any true lover of birds will recognise how 
hopeless it is to try and supplement his work 
on equal terms. Nothing but the necessity of 
cataloguing the additions which have been made 
to his collection since his death, can justify the 
Editor’s work. But if in any degree, and in one or 
two instances, he can catch the spirit of the master, 
he will be content.
