contained a vast amount of fat and carbonaceous food, as well as ingredients easily digestible and calculated to maintain one's strength even in moments of unusual stress. I had them packed in tin cases and skin bags. I carried in a water-tight box 1000 cartridges for my 256 deg. Mannlicher rifle, besides 500 cartridges for my revolver, and a number of hunting knives, skinning implements, wire traps of several sizes for capturing small mammals, butterfly nets, bottles for preserving reptiles in alcohol, insect-killing bottles (cyanide of potassium), a quantity of arsenical soap, bone nippers, scalpels, and all other accessories necessary for the collection of natural history specimens. There were three sets of photographic apparatus in my outfit, and one hundred and fifty-eight dozen dry plates, as well as all adjuncts for the developing, fixing, etc. of the negatives as they were taken. The collecting materials were given me by the British Museum of Natural History, to which institution I had promised to present all specimens of fauna and flora I might collect during my journey. I had two sets of instruments for astronomical observation and for use in surveying (one of which had been furnished me by the Royal Geographical Society), such as the six-inch sextant, hypsometrical apparatus for measuring heights, with boiling-point thermometers specially constructed for very great altitudes; two aneroids, one to 20,000 feet, the other to 25,000 feet; three artificial horizons (one mercury, the others plate-glass with levels); a powerful telescope with astronomical eyepiece and stand; a prismatic, a luminous, a floating, and two pocket compasses; maximum and minimum thermometers, a case of drawing instruments, protractors, parallel rules, tape rules, a silver water-tight half-chronometer watch and three other watches, section paper in books and in large sheets, Raper's and the Nautical Almanac for 1897 and 1898. Not to neglect the artistic aspect of my expedition, I had provided myself with ample painting and drawing materials, and I trust to the appearance of my sketches in these volumes to prove that I did not carry them in vain.
