In the course of my journey through Sennaar, I saw that all the inhabitants were well acquainted with the virtues of this plant. I had prepared a quantity pounded into powder, and used it successfully everywhere. I thought that the mixing of a third of bark with it produced the effect more speedily, and, as we had now little opportunity of getting milk, we made an infusion in water. I tried a spiritous tincture, which I do believe would succeed well. I made some for myself and servants, a spoonful of which we used to take when we found symptoms of our disease returning, or when it was raging in the place in which we chanced to reside. It is a plain, simple bitter, without any aromatic or resinous taste. It leaves in your throat and pallet something of roughness resembling ipecacuanha. This shrub was not before known to botanists. I brought the seeds to Europe, and it has grown in every garden, but has produced only flowers, and never came to fruit. Sir Joseph Banks, president to the Royal Society, employed Mr Miller to make a large drawing from this shrub as it had grown at Kew. The drawing was as elegant as could be wished, and did the original great justice. To this piece of politeness Sir Joseph added another, of calling it after its discoverer’s name, Brucea Antidysenterica: the present figure is from a drawing of my own on the spot at Ras el Feel. The leaf is oblong and pointed, smooth, and without collateral ribs that are visible. The right side of the leaf is a deep green, the reverse very little lighter. The leaves are placed two and two upon the branch, with a single one at the end. The flowers come chiefly from the point of the stalk from each side of a long branch. The cup is a perianthium divided into four segments. The flower has four petals, with a strong rib down the center of each. In place of a pistil there is a small cup, round which, between the segments of the perianthium and the petala of the flower, four feeble stamina arise, with a large stigma of a crimson colour, of the shape of a coffee-bean, and divided in the middle. CUSSO, BANKESIA ABYSSINICA. The Cusso is one of the most beautiful trees, as also one of the most useful. It is an inhabitant of the high country of Abyssinia, and indigenous there; I never saw it in the Kolla, nor in Arabia, nor in any other part of Asia or Africa. It is an instance of the wisdom of providence, that this tree does not extend beyond the limits of the disease of which it was intended to be the medicine or cure.
