...first two cases in the series have just been released--Robert Boyle's Experiments in Pneumatics and The Overthrow of the Phlogiston Theory. Case three, Early Development of the Concept of Temperature and Heat, edited by Professor Duane Roller of Wabash College, will be published in a fortnight...
...pamphlet gives sample examination questions used in the course, and an example of the case material used in discussing the overthrow of the phlogiston theory. Its title is the same as the title of his course...
This is where case histories come in, and where the book takes off into new realms. President Conant proposes to take certain cases, such as Robert Boyle's experiments with the air pump or the completely fallacious and stubbornly maintained theory of phlogiston, and illustrate through them the principles of the tactics and strategy of science. As opposed to a broad historical survey, this method offers the advantages of simplicity and totality to the student, and that of greater selectivity to the instructor. The main part of the book consists of illustrations of case histories and the method of drawing...
Priestley did not know what he had made when he heated red oxide of mercury with a burning glass and collected the atmosphere caused by the process. He labored under an old notion that combustible substances had a constituent, "phlogiston," which departed from them when they burned (as soot, for example). Thus, when he found that a candle burned more brightly, and mice thrived, in the atmosphere created with his container of heated mercuric oxide, he thought this atmosphere was "dephlogisticated air." Fortunately, while touring Europe with a patron, he met the Frenchman, Lavoisier, and told him of his experiment...
