In conclusion, I ought perhaps to mention

in my dealings with the Spotted Larinus. 
Considering the scarcity of authentic data 
as to what becomes of instinct when the 
conditions of life are altered, we should do

Making ample allowance for anatomy, 
a precious aid, what do we know of animals? 
Next to nothing. Instead of inflating

collect well-observed facts, however humble. 
From a sheaf of such facts a clear, calm light
