We descended in one hour from the heights of Tala Mungongo.

I counted the number of paces made on the slope downward, and found them to be sixteen hundred, which may give a perpendicular height of from twelve to fifteen hundred feet.

Water boiled at 206 Degrees at Tala Mungongo above, and at 208 Deg.

at the bottom of the declivity, the air being at 72 Deg.

in the shade in the former case, and 94 Deg.
