only succeed by giving up to a tame healthy pair a whole room, in which a sort of grove should be formed of branches. DISEASES.--In general moulting amounts to a disease among nightingales: at this critical time they require a more succulent diet, and sometimes a spider by way of purgative. If their stomach is disordered they puff up their feathers, half shut their eyes, and remain for hours with their head under their wing. They are relieved and cured by ants' eggs, some spiders, and by giving them occasionally water impregnated with saffron till it is of an orange colour, to drink. As to those diseases which they have in common with other birds, they are treated according to the directions given in the Introduction. It is especially necessary, every three months, carefully to remove the large scales from their legs and toes. A nightingale may be kept in confinement fifteen years; whilst in a wild state they are never observed to exist so long in the same spot, which seems to prove that they do not attain so great an age when exposed to all sorts of accidents, both from birds of prey and bird-catchers. I have an instance of a nightingale which has lived twenty-five years in confinement. When they have reached six years they begin to sing less frequently and long, with less brilliancy and ornament; it is then better to set them at liberty in the month of May. The open air often invigorates them so much that they regain their song in all its force and beauty.
