the slightest desire for food, nor did we feel the want of it when we
abstained. At first we forced our appetites, but afterwards we fasted
completely. Altogether we did not consume one-hundredth part of the
compressed provisions we had brought with us. The amount of carbonic
acid we breathed was also unnaturally low, but why this was so I am
quite unable to explain.
