London:: Printed by W. Bulmer, 1810., 1810. 292 x 235 mm. 4to. Pages 16-74. [Entire issue: [iv], [2], 147, [1 blank], 26 pp.] Original plain blue wrappers; top cover off and water-stained, spine heavily chipped. Very good. First appearance of Davy's discovery of hydrogen telluride, being delivered as part of the Bakerian Lecture series for 1809. / Davy's fourth Bakerian lecture, read to the Royal Society November 16, 1809. "Contains the discovery of hydrogen telluride, further investigations on ammonium, and some hasty speculations on the supposed composition of the elements". Partington. Arguments are given for considering potassium and sodium elementary bodies. "Gave further proofs of the elementary nature of potassium, and described the properties of telluretted hydrogen.” Encyclopaedia Britannica. / "Davy began to examine the chemical effects of electricity in 1800, and his numerous discoveries were presented in his Bakerian lectures". – Wheeler. / "Mr. Davy having from the commencement of his electro-chemical researches, communicated the several steps of his progress to the Society (The Royal Society), takes the present opportunity of reporting the results of his further inquiries under four principal heads. First, on the nature of the metals of the fixed alkalis. Second, on the nature of Hydrogen and composition of ammonia. Thirdly, on the metals of the earth and fourthly he makes a comparison between the antiphlogistic doctrine, and a modified phlogistic hypothesis".
