_Medicine._--These are medicines that are essential. The most important of all is quinine. When not a physician, it is not necessary to take with you an apothecary shop. I took calomel, morphine, laudanum, rhubarb, castor-oil, Epsom salts, Fowler's solution of arsenic, ammonia, a couple of bottles of brandy to be mixed with laudanum, some lancets, and pincers. Fever and dysentery are the two diseases to be most dreaded by the white man, especially the fever. Many white men who go to Africa die of fever. I always used to take big doses of quinine--ten, twenty, thirty, forty grains at a time, and repeated those doses two or three times during the day. _Ammunition._--Let us attend to the ammunition. First we must get some good rifles that are strong and not complicated in their mechanism, for the big forest is a bad country for rust; some shot-guns, and also revolvers and hunting-knives. We must take, if we wish to make a large collection of birds to take home, hundreds of pounds of the smallest kind of shot for small birds, and then hundreds of pounds of large-size shot for larger birds; a great many cartridges, and large numbers of bullets for the rifles, and buck-shot; steel-pointed bullets and explosive bullets. Powder for ammunition must always be plentiful. My ammunition alone amounted to over ten thousand pounds. _For preserving the skin of animals and birds._--Fifty pounds of arsenical soap; arsenic, one hundred pounds; scalpels, a dozen; pincers; big knives, half a dozen; camphor. I had a peculiar way of preserving my butterflies. _Things to astonish the natives._--Musical boxes; powerful magnets; round plain Waterbury clocks; lots of matches; electric battery. Hardly anything I had astonished the natives more than my musical boxes. When I used to put these playing in the midst of the street, they thought many spirits were talking to me. They marvelled when they saw the magnet holding in the air their knives or spears. My round plain Waterbury clocks, which only cost me a dollar apiece, were of great service to me. I used to hang them outside of my huts, and the tick-tack used to frighten the natives, and they did not dare to come round my huts at night, for they thought the noise inside the clock was made by guardian spirits. The matches were objects of great curiosity to them, and a present of a box of matches to a King, or even a few matches, was highly prized by him. The electric battery used to bring terror into their hearts after they had received a shock.
