Note 31 — CHAP. IV.
Reading edition
Unfortunately the minimum and maximum thermometers were so deranged that Mr. Overweg was unable to repair them. We had no barometer, and the only aneroid barometer with which we had been provided, and which had been under the care of my companion, was damaged on our first excursion; so that nothing was left to us but to find the elevation of places by the boiling-point of water. I will here mention, for the use of future travellers, that I always wore not only my azimuth, but even my chronometer in my belt, and found this an excellent precaution against accidents of any kind.
