Salmonia; Or, Days of Fly Fishing In a series of conversations. With some account of the habits of fishes belonging to the genus Salmo

"Salmonia; Or, Days of Fly Fishing" by Sir Humphry Davy is a philosophical treatise interwoven with personal reflections and natural history, likely written in the early 19th century. The work unfolds through a series of conversations among four fictional characters—Halieus, Ornither, Poietes, and Physicus—who engage in discussions that extol the joys and intricacies of fly fishing. The text not only explores the art of angling but also delves into the habits of fish, particularly within the genus Salmo, shedding light on the broader connections between nature and human experience. At the start of the book, the characters introduce themselves and engage in a spirited debate about the merits of fly fishing, with Halieus defending the practice against the criticism of Physicus, who is skeptical about its ethics. This opening dialogue sets the stage for a contemplative exploration that blends personal anecdotes with reflections on nature, moral philosophy, and observations of aquatic life. The conversation shifts between a defense of angling as a noble pursuit and an inquiry into the biological instincts of fish, demonstrating the author's passion for both fishing and natural philosophy. Overall, the opening portion establishes a leisurely yet intellectually stimulating tone that invites readers into the serene world of fly fishing and its deeper implications.

Sir Humphry Davy, 1st Baronet, was a British chemist and inventor who invented the Davy lamp and a very early form of arc lamp. He is also remembered for isolating, by using electricity, several elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as for discovering the elemental nature of chlorine and iodine. Davy also studied the forces involved in these separations, inventing the new field of electrochemistry. Davy is also credited with discovering clathrate hydrates.
