Context

“he offered it to us each in turn, and this generous beverage cheered us up slightly. "Forträfflig," said Hans, drinking in his turn. "Excellent," replied my uncle. A glimpse of hope had returned, although without cause. But our last meal was over, and it was now five in the morning. Man is so constituted that health is a purely negative state. Hunger once satisfied, it is difficult for a man to imagine the horrors of starvation; they cannot be understood without being felt. Therefore it was that after our long fast these few mouthfuls of meat and biscuit made us triumph over our past agonies.” source
