PUBLISHER’S NOTE. 
THE World’s Congress on Ornithology was held in con- 
formity with the announcement of the Committee, in Hall 
No. 23 of the Memorial Art Palace, at 2 Pp. m. of Wednesday, 
Thursday, Friday, and Saturday, Oct. 18th-21st, 1893. The 
few weeks intervening between the appointment of the Com- 
mittee and the sessions of the Congress did not enable the 
Committee to do all they wished to mature their plans for 
the co-operation of ornithologists living at a distance from 
Chicago, but they had reason to be much gratified at the 
measure of success attained, as witnessed by the large and 
interested audiences which attended every session, and the 
many papers which were read in person or by proxy. In the 
unavoidable absence of President Coues the chair was oc- 
cupied by other members of the Committee. The opening 
address was made by the late Rev. Dr. David Swing, who 
was followed by Rev. Jenkin Lloyd Jones, Prof. D. D. Mc- 
Cormick, and others. The programme prepared for the four 
sessions, and printed at the time, was carried out as far as 
possible, but some changes were necessitated by delay or 
non-reception of some papers which had been expected, and 
others were made for the convenience of those who presented 
papers in person. The papers selected for publication by 
the Committee include among those which were read before 
the Congress a number which reached their hands too late 
to be placed upon the programme of the sessions. 
The responsible editor, Dr. Elliott Coues, has given per- 
sonal supervision to every paper, and has read the proof of 
the entire book.
