The mongous is less than the maucauco, but his hair is likewise short, silky, and a little curled. His nose is thicker, and resembles that of the vari. I had a mongous in my possession for several years; his coat was brown, his eyes yellow, his nose black, and his ears short. He had a custom of playing with, and biting his own tail, and by this method destroyed four or five of the last vertebræ. He was very slovenly, and so troublesome that we were obliged to keep him chained. Whenever he got loose, he visited the shops in the neighbourhood, and would make free with fruit, sugar, sweetmeats, &c. and to obtain which, he would open the boxes that contained them. At such times it was difficult to retake him, and he would bite even those he best knew. He was almost continually grumbling, and when weary of being alone, he made a loud noise which somewhat resembled the croaking of a frog. This was a male animal, and had extremely large testicles for the size of his body. He was fond of she-cats, but his connection with them was too slight to be productive. He was very fearful of the cold and wet, and never stirred far from the fire-side, where he sat upright to warm himself. He was fed with bread and fruits; his tongue was rough, like that of a cat, and he would lick a person's hand until it became inflamed, and if not guarded against would generally end with a bite. He died with the cold in the winter, 1750, although he never stirred from the fire-side. He was very brisk in his motions, and sometimes petulant. He often slept in the day, or rather dozed, for his sleep was so light, that he was disturbed with the least noise. There are many varieties of the mongous both in colour and size. The one we have just mentioned was quite brown, and about the size of a middling cat. We saw one which, though adult, was not bigger than the loir. If this small mongous had not perfectly resembled the great one in every respect but in size, it would certainly have been a different species; but the resemblance was so perfect, that we think ourselves justifiable in ranking them together.
