This case being beyond my skill, I could only prescribe calomel pills, and a few doses of salts. I also presented the mother with a few needles and a thimble, for which she seemed truly grateful, pronouncing a blessing upon me as she departed. At last I had an opportunity of lying down to rest. Though suffering much from fever, I soon fell into a confused sleep, from the powerful dose of opium I had taken. Early in the morning I rose with a view of getting the greater part of my journey over before the sun should reach the meridian, but after breakfast, August 17th, some of my men beginning to dispute about carrying the luggage as previously arranged, I was compelled to use my horsewhip. The excitement produced by this disobedience suddenly threw me into a violent chill, which commenced at the feet, and rapidly rose upwards till it reached the pit of the stomach. Then sickness and vomiting began, followed by violent headach and giddiness. This kind of attack is generally a prelude to a very severe and dangerous fever. In a few minutes after the chill reached my chest, I reeled and fell prostrate; but when the violent burning of the fever commenced, the giddiness partly left me. I then took another strong dose of opium and James’s powder, and lay down for two hours. I now found myself in a violent perspiration, overcome by a sort of pleasing stupor. This enabled me to bear up against the violence of the fever. I ordered my horse to be again got ready, in defiance of the kind remonstrances of the captain of my guard, and commenced my journey, bearing magnetic W.N.W. At a short distance from the town, we passed over marble rocks, beautifully twisted; but, on entering the plain, we again found the bed composed of fused iron ore, with shea-butter and palm-trees, thinly spread over it, and many other trees, the names and class of the greater part of which were strange to me, being unacquainted with botany.
