I2S. TRAVELS ON THE RIO NEGRO. [Juty,
some large pinkish-white marbled blotches on the belly. The skin is about an inch thick on the back, and a quarter of an inch on the belly. Beneath the skin is a layer of fat of a greater or less thickness, generally about an inch, which is boiled down to make an oil used for light and for cooking. The intestines are very voluminous, the heart about the size of a sheep's, and the lungs about two feet long, and six or seven inches wide, very cellular and spongy, and can be blown out like a bladder. The skull is large and solid, with no front teeth; the vertebrae extend to the very tip of the tail, but show no rudiments of posterior limbs ; the fore limbs, on the contrary, are very highly developed, the bones exactly corre- sponding to those of the human arm, having even the five fingers, with every joint distinct, yet enclosed in a stiff inflexible skin, where not a joint can have any motion.

As I now expected a canoe shortly to arrive, bringing me letters and remittances from England, after which I was anxious to set off for the Upper Rio Negro as soon as possible, I determined to return to Barra, and having agreed for a passage in a canoe going there, I took leave of my kind host. I must, however, first say a few words about him. Senhor Jose Antonio Brandao had come over from Portugal when very young, and had married early and settled, with the intention of spending his life here. Very singularly for a Portuguese, he entirely devoted himself to agriculture. He built himself a country-house at Manaquery, on a lake near the main river, brought Indians from a distance to settle with him, cleared the
