PREFACE. 



This, the twenty-third, volume of ' The Ibis ' is larger 

 by many pages than any of its predecessors, shoAving 

 that the Editors lack neither contributions to this 

 Journal nor funds wherewith to publish them — 

 subjects on which the Members of the B. O. U. 

 may justly congratulate themselves. Long may the 

 present state of things continue !
