In England, when troublesome questions press and seem to call for new legislation, it frequently happens that the collection and sifting of evidence preliminary to legislation is a task for which the methods and routine of Parliament are unsuitable. The Queen, acting through her responsible advisers, appoints a Royal Commission, consisting of a small body of men, to which is entrusted the preliminary task of collecting and weighing evidence, or of making recommendations on evidence already collected. To such honourable posts Huxley was repeatedly called. He served on the following Commissions: 1. Royal Commission on the Operation of Acts relating to Trawling for Herrings on the Coast of Scotland, 1862. 2. Royal Commission to Enquire into the Sea Fisheries of the United Kingdom, 1864-65. 3. Commission on the Royal College of Science for Ireland, 1866. 4. Commission on Science and Art Instruction in Ireland, 1868. 5. Royal Commission on the Administration and Operation of the Contagious Diseases Acts, 1870-71. 6. Royal Commission on Scientific Instruction and the Advancement of Science, 1870-75. 7. Royal Commission on the Practice of Subjecting Live Animals to Experiments for Scientific Purposes, 1876. 8. Royal Commission to Enquire into the Universities of Scotland, 1876-78. 9. Royal Commission on the Medical Acts, 1881-82. 10. Royal Commission on Trawl, Net, and Beam-Trawl Fishing, 1884. This is a great record for any man, especially for one in whose life work of this kind was outside his habitual occupation. It was no doubt in special recognition of the important services given his country by such work, as well as in general recognition of his distinction in science, that he was sworn a member of Her Majesty’s Privy Council, so attaining a distinction more coveted than the peerage.
