An account of a useful discovery to distill double the usual quantity of sea-water, by blowing showers of air up through the distilling liquor : $b and an account of the great benefit of ventilators in many instances, in preserving the health and lives of people, in slave and other transport ships .

Description

Experience a foundational text in the history of medicine and engineering. Stephen Hales presents two groundbreaking discoveries that fundamentally changed maritime safety and public health. The first half details his revolutionary method for doubling the output of seawater distillation by blowing air through the liquor — a technique that became essential for long voyages. The second half argues for the widespread use of ventilators on ships, demonstrating how improved air circulation saved countless lives among sailors and passengers alike.\n\nThis is not just a historical document; it is a testament to the power of empirical observation and practical problem-solving. Hales's clear, persuasive writing makes complex engineering and medical concepts accessible to any reader. Whether you are a student of the history of science, a maritime enthusiast, or simply interested in the evolution of public health, this work offers invaluable insights into how simple innovations can have profound consequences. The EPUB format allows you to read Hales's original text on any device, making this classic of the Enlightenment era available to modern readers everywhere.
