CONCLUSION 161 
but a reasonable faith in one’s own work coupled 
with the respect that is due to one’s predecessors 
and contemporaries in the great and honourable 
fraternity of working naturalists. 
In the first chapter I quoted the motto of the 
Linnean Society, ‘‘ Nature discere mores,” and through- 
out these pages I have endeavoured to point out 
one way in which to respond to the call. The 
motto of our premier learned Society, the Royal, 
consists again of only three words, * Nullius in 
verba,”’ and the reader will no doubt understand and 
appreciate the significance of the genitive singular. 
If he will also recall what I wrote, when dealing in 
Chapter III. with mutual competition, anent the 
definition of the word “‘ Nature,” he will grasp my 
meaning when I say that he should bear both mottoes 
steadily in mind and keep the fear of them always 
before his eyes, for upon the correct interpretation of 
these two hang all religion, every step upward in 
the advancement of learning, and the whole duty of 
the Nature-student.
