impressions. As he extends the range 
of his observations, he will meet with 
more cases of difficulty ; for he will en- 
counter a great number of closely-allied 
forms. But if bis observations be widely 
extended, he will in the end generally be 
enabled to make up his own mind which 
to call varieties and which species ; but 
he will succeed in this at the expense 
of admitting much variation, — and the 
truth of this admission will often be dis- 
puted by other naturalists. 
“ When, moreover, he comes to study 
allied forms brought from countries not 
now continuous, in which case he can 
hardly hope to find the intermediate 
links between his doubtful forms, he 
will have to trust almost entirely to 
analogy, and his difficulties will rise to a 
climax.” 
Perhaps when you have a convenient 
opportunity you may be able to find a 
corner for this scrap.
