APPENDIX II. 
consultation with several of his friends (including myself, 
■whom he had asked to aid him in preparing the new 
edition for the press), accordingly decided to reprint ‘ The 
Structure and Distribution of Coral Eeefs ’ from the 
edition of 1874, subject only to a few press corrections, and 
to give any important emendations or additions in the 
form of notes, so arranged as to be easily distinguished 
from those written by the late author. As regards the 
extent and amount of the additional matter, we thought 
that, as the volume was never intended as a text-book 
for examination purposes, it was needless to endeavour to 
concentrate within its pages every result of recent work, 
and it would suffice to call attention to the more important 
points, which would almost certainly have been noticed by 
the author in any new edition. 
Therefore, from a few papers left by Mr. Darwin, from 
information kindly supplied by Capt. Wharton and other 
friends, and from my own reading, I have added a few foot- 
notes to the text, and have given in this appendix a summary 
of the papers which appeared to me of special importance 
among those which have been published since 1874. No 
attempt has been made to compile a bibliography of the 
literature of ‘ Coral Eeefs.’ This was a task, as I told Mr. 
F. Darwin candidly at the outset, which my previous studies 
and present occupations would not permit me to undertake, 
and it was also one which, for the reason above given, seemed 
to me needless. I believe, however, that I have looked 
through most of the recent literature, and I have selected 
therefrom certain papers, in which, as it seemed to me, the 
arguments for and against Mr. Darwin’s theory were 
stated with considerable fulness. The remainder have been 
passed over, either because they did not contain original 
information, or because they would have supplied additional 
details, on the one side or the other, rather than fresh 
arguments. In making this selection I have been influenced
