The younger the animals are, the easier it is to accustom them to live in cages. They will require, at first, particular care; it will be well to feed them for some weeks on shore before shipment, and too much pain cannot be taken to tame them. An animal that is not frightened at the sight of those who take care of him, is always in better health and resists more easily the fatigues of a sea-voyage than one who remains wild, and there is scarce any animal that does not yield to kind treatment. Nourishment in excess, when they are shut up, and without the power of taking exercise, would be injurious. The surest way of keeping them is merely to give them what is necessary. After a suitable nourishment, cleanliness is most necessary to them. Often, on shipboard, some one would be found who will take care of them, either for amusement or a slight remuneration. It is essential to take precautions to prevent the animals being teased and irritated by passengers. As there are always difficulties in the transportation of living animals, there is an easier way whose results are more extended; that is the spoils of dead animals. Quadrupeds can be procured either by sending hunters in the interior of the country, or by applying to the natives of the country. They will content themselves with bringing the skin, the bony head and feet of the great animals that they have killed in places too remote to be preserved or transported entire. The mammifers of a size small enough to be enclosed in a jar or cask, should be put in alcohol. Those that are too large to preserve in this manner should be skinned, and care should be taken to send with the skin the feet and head, with the brain taken out, or if that cannot be done, the jaws, at least, should be sent. In preparing the head, care should be taken not to damage the skull. The brain can be extracted with care without increasing the occipital hole. We shall speak, further on, of the means to be employed and the precautions to be taken for the preservation of the skins and for that of animals placed in alchool. When the skeleton of the animals can be joined to the skin, a great service will be rendered to science. The officers can entrust with this care the surgeons of the ships, for whom this operation will be easy. It is not necessary that the skeletons should be set up. After having boiled the bones, taken of the flesh and dried them well, all those of the same animal should be put in a cloth-sack with moss, sea-weed, rolls of paper, or some other soft and dry matter that they may not rub one agains the other. Those that are very frail should be enveloped with paper and care should be taken not to lose any.
