He was only twenty-three when the incident occurred, but he resolved in future never to take anything for granted, or to accept theories which were not well supported by trustworthy experiments.

Liebig was a man of untiring labour, always at work, early and late, and his discoveries and philosophy have proved of the highest importance to mankind.

Liebig's books on Animal Chemistry (1842), Researches on the Chemistry of Food (1847), The Natural Laws of Husbandry (1862), etc., have been translated into most of the languages of Europe.

Liebig often visited England, and attended several meetings of the British Association. In 1837 he was requested by the Association to draw up a report on the
