THE INFLUENCE OF THE BLUE RAY OF THE SUNLIGHT AND OF THE BLUE COLOUR OF THE SKY In Developing Animal and Vegetable Life; in Arresting Disease, and in Restoring Health in Acute and Chronic Disorders to Human and Domestic Animals
Book Details + Condition: Claxton, Remsen & Haffelfinger (Philadelphia). Very scarce First Edition (Second Impression), 1877. 185 pages. Illustrated by the author, Gen. A. J. Pleasonton (and Others). Lecture addressed to the Philadelphia Society for Promoting Agriculture. Dark blue boards with gilt lettering on front and spine; interior has pale blue pages. An unusual work on the influence of light and color on nature and health. This edition, which was first printed just a year earlier - is an expanded rendering of Pleasonton's 24 page pamphlet "On the Influence of the Blue Color of the Sky", first published in 1871. The work outlines Pleasonton's theory that blue wavelengths from the sun are inherently unique and that they are especially influential in the growth of plant and animal life. He includes the results of his own experiments conducted between 1873-1876 and his extensive meteorological and oceanographic observations. The work is thought to have been influential on Edwin Babbitt who soon after wrote the groundbreaking: "Principals of Light and Colour" (1878), as well as "Blue and Red Light; or, Light and Its Rays as Medicine" by Dr. S. Pancoast (1877). Tight binding; rubbed corners and edges; normal light shelf wear to boards; text is clean and unmarked; includes publisher advertisement pasted on to back inside board.
