Experiments and observations on different kinds of air (1774–86) is a six-volume work published by 18th-century british polymath joseph priestley which reports a series of his experiments on airs or gases, most notably his discovery of oxygen gas (which he called dephlogisticated air).
To experiment is to isolate, prepare, and manipulate things in hopes of producing epistemically useful evidence. It had been customary to think of observing as noticing and attending to interesting details of things perceived under more or less natural conditions, or by extension, things perceived during the course of an experiment.
Experiments and further observations are often used to test the hypotheses. A scientific experiment is a carefully organized procedure in which the scientist intervenes in a system to change something, then observes the result of the change. Scientific inquiry often involves doing experiments, though not always.
Benjamin franklin beginning in 1747 describes experiments in letters to peter collinson demonstrating electrical principles which were published in a book called experiments and observations on electricity. Alessandro volta constructs a new source of electricity, the electrical battery (1796).
