An essay on the preservation of shipwrecked mariners : in answer to the prize-questions proposed by the Royal Humane Society : "1. What are the best means of preserving mariners from shipwreck?-2. Of keeping the vessel afloat?-3. Of giving assistance to the crew, when boats dare not venture out to their aid?"

In this clear‑sighted treatise, a learned physician turns his analytical mind to the pressing dangers that beset Britain’s seafarers. He lays out practical measures for preventing shipwrecks, from strengthening hulls to improving navigation, while also proposing inventive ways to keep a damaged vessel buoyant long enough for rescue. The essay draws on recent experiments and the collective experience of naval officers, offering concrete ideas such as buoyant cages, signaling devices, and shore‑based communication lines that could buy precious moments for crews in peril.

Beyond the technical advice, the author reflects on the humanitarian stakes of maritime loss, emphasizing that the value of a single life outweighs any commercial cargo. By weaving scientific reasoning with a genuine concern for human welfare, the work invites readers to consider how modest innovations might dramatically reduce the tragedy of shipwrecks on Britain’s bustling seas.
