my companions all the way to the town, and answering nobody when spoken to; many days elapsed before I felt myself perfectly recovered from this accident. Understanding that a very large deposit of fossil fishes existed at a place called Mundo Novo, about three leagues to the west of Barra do Jardim, I determined on making an excursion there prior to my departure. To effect this object it was necessary to cross a branch of the Serra de Araripe, at a point where as on the road to Maçapé, the ridge tends north and south; it is here, however, only about two leagues and a half broad. On my way I found two or three trees quite new to me, one being of large size, the _Copaifera nitida_, Mart., then covered with a profusion of small white flowers; its trunk yields an abundance of oil, which is employed in the cure of ulcers, and for frictions in cases of rheumatism. After crossing the Serra, I found the country still more dried up than at Jardim, the sides of the mountain exhibiting only a few green trees; along the foot of the Serra some fine large trees were seen, but as they were then destitute of both leaves and flowers I could not ascertain to what tribe they belonged; they are called Braúna by the natives, and afford an excellent timber, which is both hard and durable, being employed in the construction of sugar-mills, particularly for rollers. I also now saw for the first time, the remarkable _Chorisia ventricosa_, Nees et Mart., called Barriguda by the inhabitants, from the shape of its stem, which swells in the middle to five times the diameter of its upper and lower portions. About half a league to the N.W. from the foot of the Serra, we reached the first habitation on the way, which belonged to the person to whom I was recommended; he received me very kindly, and invited me into the house, which was little better than a mere hut; upon learning the object of my visit, he kindly offered to accompany me to the spot. After partaking of breakfast we started, and in about half an hour reached the place; as in all the instances I had before met with, it occupied an isolated spot of considerable extent on the gentle slope of a low ridge, which runs along the base of the Serra: here also, as in other places, almost every stone contains the remains of a fish in a more or less perfect condition; most of the smaller ones, that were only four or five inches long, were perfectly entire, but the larger ones, some of which measured fully six feet,[7] were always in fragments. After three hours labour, I collected many tolerably perfect specimens, but no species different from those already obtained in other places. On returning with my companion to his house, an excellent dinner was prepared, for which he refused any recompense. The kindness I received on this occasion was indeed greater than could be expected from a person in his poor circumstances; I was glad, however, to have an opportunity of
