One more kind of secondary sexual character must here be mentioned: the odour which emanates from so many animals at the breeding season. It is possible that this odour also served at first merely to give notice of the presence of individuals of the other sex, but it soon became an excitant, and as the individuals which caused the greatest degree of excitement were preferred, it reached as high a pitch of perfection as was possible to it. I shall confine myself here to the comparatively recently discovered fragrance of butterflies. Since Fritz Mueller found out that certain Brazilian butterflies gave off fragrance "like a flower," we have become acquainted with many such cases, and we now know that in all lands, not only many diurnal Lepidoptera but nocturnal ones also give off a delicate odour, which is agreeable even to man. The ethereal oil to which this fragrance is due is secreted by the skin-cells, usually of the wing, as I showed soon after the discovery of the _scent-scales_. This is the case in the males; the females have no _special_ scent-scales recognisable as such by their form, but they must, nevertheless, give off an extremely delicate fragrance, although our imperfect organ of smell cannot perceive it, for the males become aware of the presence of a female, even at night, from a long distance off, and gather round her. We may therefore conclude, that both sexes have long given forth a very delicate perfume, which announced their presence to others of the same species, and that in many species (_not in all_) these small beginnings become, in the males, particularly strong scent-scales of characteristic form (lute, brush, or lyre-shaped). |
In Switzerland, one of the chief employments of the people is that of herdsmen and shepherds, and nearly the half of the surface of the country is occupied as mountain pastures and meadows. Here you see the woman tending the sheep and goats, and spinning industriously, while her husband is busy with some other part of the duties of tending the sheep. It is often painful to see how much the poor sheep and oxen suffer while being driven through the streets. It is pitiful to see them looking in vain for some place of rest and shelter. Little boys in towns sometimes like to HELP--as they call it--to drive cattle, but they generally increase the terror and confusion of the poor beasts, and little think of the pain they are causing. Sheep and goats are very useful to us; besides serving us for food, they supply our cloth and flannel clothes, blankets, and other warm coverings. |
