ago I was much struck
a remark,
to the above effect,
by Mr.
→Waterhouse.
→I infer also from an observation made by
Professor Owen,
→with respect to the length of the arms of the ourang-outang, that he has
come to a nearly similar conclusion. It is hopeless to attempt to convince any one of the truth of
proposition without giving the long array of facts which I have collected, and which cannot possibly be here introduced. I can only state my conviction that it is a rule of high generality. I am aware of several causes of error, but I hope that I have made due allowance for them. It should be understood that the rule by no means applies to any part, however unusually developed, unless it be unusually developed in
→comparison
with the same part in
allied species. Thus, the

abnormal structure in the class
but the rule would not
whole group of bats
it would apply only if some one species
→of bat had its
wings developed in
remarkable manner in comparison with
other species of the same genus. The rule applies very strongly in the case of secondary sexual characters, when displayed in any unusual manner. The term, secondary sexual characters, used by Hunter,
to characters which are attached to one sex, but are not directly connected with the act of reproduction. The rule applies to males and females; but
→as females more rarely
offer remarkable secondary sexual
The rule being so plainly applicable in the case of secondary sexual characters, may be due to the great variability of these characters, whether or not displayed in any unusual
of which fact I think there can be little doubt. But that our rule is not confined to secondary sexual characters is clearly shown in the case of hermaphrodite cirripedes;
