The _pinham_ requires less rain and grows quicker than the _molungo_, but it is without thorns, and the plant is not nearly so large. The seed of the _pinham_ is used as an emetic by the peasants, and is violent in its operation, a very small quantity being sufficient even for an adult. The fruit incloses three seeds, and is about the size of the common hazel-nut. During the third attack of ague which I had whilst I was at Jaguaribe, I placed myself under the direction of an old mulatto woman, than whom I never saw any one more like a witch; and indeed poor old Antonia had the reputation of being somewhat of a _mandingueira_. However she gave me a dose of _pinham_, which, I think, consisted of four seeds, but they were picked out from a heap of others for their superior size. The dose acted most violently and effectually produced vomiting, and although excessive weakness followed the disorder was removed. I begged her to give me a quantity equal to what she had administered, that I might take it to Recife; this I shewed to a practitioner, who answered that he should have imagined that such a dose would have killed any one; but the old reputed sorceress knew full well, that a dangerous disease requires to be severely attacked[131]. After the ague left me, my nurse would not be satisfied until she applied the bark of the _mutamba_ tree to my stomach; or rather the application was made just below the ribs, which she said was to prevent _dureza_; this she described as a hardness immediately under the lower rib of each side, which sometimes was produced by the ague, and which, if precautions were not taken in time ended in dropsy. I did not suffer her to continue the _mutamba_ for many days, for I found that I was well, and wanted no more nostrums. The _mutamba_ is a small tree, having a straight stem; it grows to the height of eighteen or twenty feet, and to the diameter of twelve or eighteen inches. The bark is easily torn off, and is extremely glutinous. The _Gameleira preta_ (black,) so called from the dark colour of its bark, is a large tree which grows in low marshy grounds; the stem contains a white juice, which is much sought for as a medicine in all eruptive complaints and in dropsy; it is likewise given inwardly. The juice is obtained by making an incision in the stem, and leaving a vessel into which the liquid may drop. There is another species of the same tree, which is distinguished by the name of white _gameleira_, and this is useless.
