"RAMSAY, WILLIAM & JOHN SHIELDS. - MOLECULAR SURFACE ENERGY SHOWN.
Reference : 44170
(1894)
(London, Harrison and Sons, 1894). 4to. No wrappers as extracted from ""Philosophical Transactions"", 1893, Vol. 184. Pp. 647-673 a. 2 plates.
First appearance of an importent paper in the history of physical chemistry in which the authors for the first time shows experimentally that ""the molecular surface energy decreases linearly with the temperature, and that the temperature coefficient of molecular surface energy is a colligative property. Determination of the temperature coefficient of molecular surface energy, therefore, were largely employed for the purpose of calculating the molecular weights, and therefrom the molecular complexity, of substances in the liquid state.""(Findley ""A Hundred years of Chemistry"", p. 79).
(London, Taylor & Francis, 1869) Large 4to. Without wrappers. Extracted from ""Philosophical Transactions of the Royal Society of London."". 1868. Vol. 158. Pp. 333-345 a. 3 fine lithographed plates.
First appearance of this paper in which Phillips summarizes his importen work on the moons surface.""In 1852 John Phillips brought maturee geological experience to his own personal observations of the physiocal features ofthe surface of the moon, using first the great telescope belonging to the Earl of Rosse...The drawings (of surfaces of the moon) were to be made under a set of standard conditions of representation and on a uniform scale...By 1853 he was recording his observations photographically on collodion palets and employing his great artuistic skill in accurate and detailled drawings...In a summary of his findings published in 1868 (the paper offered), Phillips drew vivid analogies between many of the features seen on the surfaceof the moon and those known to him intimately by observation and measurement on the earth.""(DSB X, p. 584.).
