Excerpt from Annals of Philosophy, or Magazine of Chemistry, Mineralogy, Mechanics, Natural History, Agriculture, and the Arts, Vol. 12: July to December, 1818When gases are subjected to very small ressures, there does not appear to be any connexion between t eir specific gravities and t e time which they take in ¿owing out through small tubes. Olefiant gas asses with as much facility. As hydrogen, and twice as rapi y as carbonic oxide and common air. Carbonic acid escapes much more rapidly than gases inferior to it in density. Analo ous results are obtained even under consider able pressures w en the caliber of the tube is sufficiently dimi nished. The time of flowing out in such cases presents anomalies, probabl owing to some loss of force in the tube, and it offers to mathematicians an interesting object of research - (ro Institution Journal, iii.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
