In regard to the second, I think few will deny that man enjoys a vested right to make use of any of the inferior animals, even to the taking of their life, if the so doing ministers to his own well-being or pleasure, and practically every one assumes this right in one way or another. Game animals are shot down (and they assuredly _do_ feel pain), not as necessaries of life, but confessedly as luxuries. Fish are hooked, crabs, lobsters, shrimps perish by thousands, victims to our fancies. Unscrupulously we destroy every insect whose presence displeases us, harmless as they may be to our own persons. The _aphides_ on our flowers, the moths in our furs, the "beetles" in our kitchens--all die by thousands at our pleasure. Then, if all this be right, are we not also justified in appropriating a little butterfly life to ourselves, and does not the mental feast that their after-death beauty affords us at least furnish an equal excuse for their sacrifice with any that can be urged in favour of any animal slaughter, just to tickle the palate or minister to our grosser appetites? To this query there can be, I think, but one fair answer, so we may return with a better face to the question, "How to kill a butterfly." [Illustration: VIII.] {53} I have alluded above to a painless mode of doing so, doubtless applicable to all insects. I know it answers admirably with the large moths, so tenacious of life under other circumstances. This potent agent is _chloroform_, whose pain-quelling properties are so well known as regards the human constitution. There is a little apparatus[8] constructed for carrying this fluid safely to the field, and letting out a drop at a time into the box with the captured insect, taking care that the drop does not go on to the insect. Or a wide-mouthed bottle may be used, having at the bottom a pad of blotting-paper, or some absorbent substance, on which a few drops of chloroform may now and then be dropped. The insect being slipped into this, and the stopper or hand being placed over the bottle's mouth, insensibility (in the insect) follows immediately, and in a few minutes, at most, it is completely lifeless. But the usual and quickest mode of despatch is by _a quick nip between the finger and thumb applied just under the wings_, causing, for the most part, _instantaneous death_: and this can be done through the net, when the {54} inclosed butterfly shuts his wings, as he usually does when the net wraps round him. Now take one of your thin pins, and pass it through the thorax of the butterfly, while open or shut, and put it into the corked lining of your pocket-box. So secured, the butterfly will travel uninjured till you reach home; but a heap of dead butterflies in a box together will, in the course of a long walk, so jostle together, as to entirely destroy each other's beauty, rubbing off all their painted scales, when, of course, they are as butterflies no longer.
