seen her run five or six times round the wall of the yard with it in her mouth, and only stop to take breath, devour the meat, or attack the dog if he came near. The dog was stronger than the wolf, but as he was less ferocious, we began to have some fear for his life, and therefore put him on a collar. After the second year their quarrels were sharper, and their combats more frequent, when a collar was also put upon the wolf, whom the dog began to treat more roughly. During these two years there was not the least appearance of desire in either of them; towards the end of the third they began to discover some marks of it, but it was without any signs of love, and instead of rendering them more gentle when they approached each other, they became ferocious and ungovernable. Nothing was now heard but dismal howlings mixed with cries of anger; in about three weeks they both grew very thin, and never came near each other without indications of mutual destruction. At length they grew so enraged and fought so dreadfully that the dog killed the wolf; and I was obliged to have the dog killed a few days after, because as soon as he was set at liberty, he sprung with fury on the poultry, dogs, and even men. At the same time I had three young foxes, two males and a female, which had been taken with snares and kept in separate places. I had one of these fastened with a long light chain, and had an hut built to shelter him. I kept him in this manner several months, and though he seemed pensive and had his eyes constantly fixed on the country, which he could see from his hut, yet he had constantly good health and appetite. A bitch in season was put to him, but as she would not remain near the fox, she was chained in the same place and plenty of food was given them. The fox neither bit nor used her ill, and during the ten days they remained together, there was not the smallest quarrel between them, neither night or day, nor when they fed; he even approached her familiarly, but as soon as he scented his companion, the signs of desire disappeared, he returned in a melancholy manner to his hut, and no intercourse took place. When the ardour of this bitch was gone, another and even a third and fourth were put to him in the same manner; he treated them all with the same gentleness and with the same indifference; to ascertain whether it was natural repugnance, or the state of restraint he was kept in, prevented his coupling, I had a female of his own species brought to him, which he covered more than once the same day, and upon dissecting her a few weeks afterwards we found she was impregnated, and would have produced four young ones. The other male fox was successively presented with several bitches in season; who were shut up with him in a close courtyard, but he discovered neither hatred nor love to them; they had neither combats nor caresses, and he died a few months after either of disgust or melancholy.
