14 pages. Read before the British Association, September 1876 and published in the Philosophical Magazine for October 1876, this is the separately printed and paginated offprint of that presentation, regarding the conversion of gravity into other forms of energy. James Croll (1821 - 1890) a largely self-educated British geologist and climatologist, responsible for advancing "...the theory that global weather patterns would be indirectly affected by the periodic changes in the eccentricity of the earth's orbit about the sun, for a winter occurring when the earth was in the aphelion of its most eccentric orbit would be bitterly cold, and this would set in motion a chain of large-scale climatic changes resulting in large tracts of glacial land ice-an ice age. Croll postulated a global climatic feedback system, resting on the combined proven physical phenomena of the variation of eccentricity, the precession of the equinoxes, and the motion of the apsides of the orbit itself. Such a system accounted for cyclic global climate patterns..." (David Kushner in the ODNB) Title page with the small name-stamp of collector George R.
