from the circumstance that a great part of the journals of the 
various learned societies are published long after the dates given 
on their title-pages ; and several have not appeared even at the 
time of the issue of this volume, yet they will bear the date 
1864 ! Arrangements have been made to obtain such late 
publications as soon as possible after their issue ; but as it is 
of great importance that the annual volume of the ^ Record^ 
should never be delayed far beyond the middle of each year, 
it is thought advisable that such loiterers should be carried 
over to the report of the year following. 
The Contributors have great pleasure in acknowledging the 
opportunities which have been liberally afforded them of con- 
sulting numerous works in the libraries of the Zoological, 
Entomological, Linnean, and Royal Societies, in that of the 
Royal College of Surgeons, and in the Royal Library at Berlin. 
The Editor regrets very much being obliged to defer the 
Records on Ccelenterata and Protozoa fo the second volume, the 
gentleman to whom this portion was entrusted having failed to 
keep his engagement; and as this did not become apparent 
until after two months^ waiting, it was then too late to find a 
substitute. 
Finally, the Editor would crave indulgence for imperfections 
of this volume, in consideration of the difficulties which must 
necessarily attend the eommencement of such an undertaking ; 
and he would request all interested in our science to favour 
him with suggestions which may tend to the improvement and 
perfection of the ^ Record.'
