able facts detailed above; but when tested by other facts, it fails 
entirely. It is comparatively easy to invent a theory in explanation 
of a particular series of phenomena, provided we be allowed to exclude 
all collateral facts from consideration. If we look back into the history 
of any science, how many futile, though at one time universally-ac- 
cepted theories of this kind, do we not encounter. Many of these, 
however, though eventually discarded, have helped by their elabora- 
tion, to enrich our knowledge; and the wide discussion to which the 
present work has led, will undoubtedly yield the same good fruits. 
In concluding our confessedly-imperfect analysis of this noted Essay, 
we may perhaps be allowed to state, apologetically, that having been 
disappointed of a review on the subject, by another pen, we have been 
forced, at the eleventh hour, to throw thus hastily into form, the 
thoughts suggested to us by an impartial study of the work when 
first obtained. If we have been compelled to record our protest 
against the reception of what we believe to be an unfounded theory, 
no one, we may safely affirm on the other hand, can lay down Mr. 
Darwin’s book, so remarkable in many points of view, without feeling 
that a large accession of new thought has been added by it to our 
common store. E, J.C.

LIST OF BIRDS OBSERVED IN THE VICINITY OF HAMILTON, C. W. 
ARRANGED AFTER TERE SYSTEM OF AUDUBON 
BY THOMAS M°ILWRAITH, ESQ. 
The object of the writer in preparing the following list, has been to afford such 
information as may be of use, should inquiry at any future period he made re- 
garding the birds frequenting this part of the country. In its present state, the 
list has been drawn up from observations made during occasional excursions 
within a period of four years. Those who are acquainted with the subject will 
see that it is necessarily incomplete; but it will be easy to add the names of 
such species as may yet be found. In order that the list may be strictly local, no 
species has been mentioned which has not been found within six miles of the 
eity limits. 
shi Genus Buteo.—Buzzarp. 
1. B. borealis—Red-tailed Hawk. Seen in spring and fall. Not very common. . 
_ 2. B. lineatus—Red-shouldered Hawk. More plentiful than the preceding, 
which it resembles in appearance and habits.
