Excerpt from On the Influence of the Blue Color of the Sky in Developing Animal and Vegetable Life: As Illustrated in the Experiments of Gen. A. J. Pleasonton, Between the Years 1861 and 1871, at Philadelphia; Read Before the Philadelphia Society for Promoting Agriculture, on Wednesday, May 3, 1871
The first edition of the following memoir was printed for distribution among scientific and literary institutions, and among persons of culture, for the purpose of attracting the attention of those for whom it was intended, to the subjects of which it treats. It was hoped that its publication would invite investigation into the nature, composition, and influences of those great forces which, in the poverty of our language, we call imponderables, that is to say, not to be weighed in the balance, and consequently never to be found wanting. This expectation is likely to be realized, if we may judge from the general interest that appears to be taken in the memoir, which has been manifested in the numerous applications that have been made to the author, from various parts of our country, for copies of it. The edition has now been distributed, yet so many persons who have applied for copies of the memoir are still without it, that it has been deemed advisable to issue another edition.

Paperback. Condition: New. Print on Demand. This book explores the profound effects of the sky's blue color on plant and animal life. Inspired by the scientific advances of the 17th and 18th centuries, the author conducted a decade of experiments with colored glass, culminating in the construction of a cold grapery and a piggery to test his hypothesis. The results demonstrated a striking acceleration of growth and development in both plants and animals exposed to violet light, suggesting its role in photosynthesis and cellular stimulation. The author argues that this blue light, particularly intense in tropical and arctic regions, contributes to the distinctive characteristics of life in these environments. By delving into the relationship between light, electricity, and vital processes, this book provides intriguing insights into the fundamental forces that shape the natural world and offers a fresh perspective on the importance of the sky's blue hue to the balance of life on Earth.
