Synopsis
Excerpt from The Philosophical Magazine and Journal, Vol. 49: Comprehending the Various Branches of Science, the Liberal Arts and Fine Arts, Geology, Agriculture, Manufactures and Commerce; For January, February, March, April, May, and June, 1817
In the course of our experiments we have met with no sub stance sufficiently refractory to resist its intensity of ignition. Some of these experiments have been detailed by Dr. Clarke but I deemed it best to submit an unbroken series and such of them as have been described by Professor Clarke will find a full corro horation in our repetition. We are even now only upon the threshold of discovery. The rays of chemical science are bounded by no horizon mightier wonders remain to be revealed.
I am, with very great respect, sir, Your obliged and faithful servant, London, January 22, 1817. J. Murray.
P. S. Two emeralds were fused into one mass, exhibit ing, during fusion, a light too vivid for the eye to endure without safer-ing. The beautiful globule thence obtained had become limpid and colourless, with the exception of a band or zone of enamel, like a horizon, circling the spherical mass. The specimen is in possession of Geo. Rennie, Esq. Who, as well as in the other experiments, joined me in this.

Paperback. Condition: New. Print on Demand. This book explores the progression of human understanding regarding the magnetic field of the Earth. The author begins by summarizing the historical development of the 'magnetic equator', the invisible line encircling the planet where magnetic dip is zero. From there, they examine the existing lines without variation, where compasses indicate true north, and the lines of greatest variation. Questions are raised in the text regarding the movement or potential non-existence of these lines, along with a discussion of how a fourth line of no variation might have been discovered. The book relies on observations and experiments by experts in the field like La Perouse, Captain Cook, and Humboldt. The author concludes by considering the implications and applications of these discoveries, including their potential role in determining longitude and their impact on the development of navigation as a practice.
