FIRST EDITION. The experiments that Hales describes in this book are principally concerned with the health and welfare of sailors, and how the food and water on a ship, which on a long voyage were notoriously bad, may be preserved in an edible state. Hales also published a proposal for improving the ventilation on board ships. Neville I, p. 576.
