In the following chapters, I shall treat <strong>of</strong> the<br />

secondary sexual characters in animals <strong>of</strong> all<br />

classes, and shall endeavour in each case to<br />

apply the principles explained in the present<br />

chapter. <strong>The</strong> lowest classes will detain us for a<br />

very short time, but the higher animals, especially<br />

birds, must be treated at considerable<br />

length. It should be borne in mind that for reasons<br />

already assigned, I intend to give only a<br />

few illustrative instances <strong>of</strong> the innumerable<br />

structures by the aid <strong>of</strong> which the male finds<br />

the female, or, when found, holds her. On the<br />

other hand, all structures and instincts by the<br />

aid <strong>of</strong> which the male conquers other males,<br />

and by which he allures or excites the female,<br />

will be fully discussed, as these are in many<br />

ways the most interesting.<br />
