vi PREFACE. 
of the marine animals figured may be found upon 
our coasts at low tide. 
In conclusion, I wish to express my great obliga- 
tion to Mr. R. Garnett of the British Museum, for his 
most kind assistance in finding works of reference on 
the special subjects ; and to many men of science, 
especially Mr. Lowne, F.R.C.S., and Mr. Haddon, De- 
monstrator of Comparative Anatomy at Cambridge, 
for their valuable criticisms on the proof-sheets. 
The Illustrations of the marine animals have been 
drawn by Dr. Wild, artist of the ' Challenger' Expedi- 
tion, and those of the insects by Mr. Edwin Wilson, 
to both of whom my thanks are due for the care 
and assiduity with which they have carried out my 
instructions.
