Steam is Condensible into water, and when you lower the temperature of steam, you convert it back into fluid water; but I have lowered the temperature of the gas which I have collected in this jar, by passing it through water after it has traversed the iron barrel, and still it does not change back into water.

But, besides that, something is going out at the top: it is not moisture-it is not water-it is not Condensible; and yet, after all, it has very singular properties.

If anything is to be inferred, either from the Nebular Hypothesis, or from the analogies supplied by the planets, it must be concluded that the outermost part of the solar atmosphere consists of what are called permanent gases-gases that are not Condensible into fluid even at low temperatures.
