She carried the brimming cup of her inestimable virtues with a cautious, steady hand, and an eye always on them, to see that they did not spill. Then she was an admirable judge of character. Her mind was a perfect laboratory of tests and reagents; every syllable you put into breath went into her intellectual eudiometer, and all your thoughts were recorded on litmus-paper.

I am doubtful of the first of these mixtures, though so common in thermal waters; for example at Aix la Chapelle, Enghien, and Bareges. The gas collected in the tube of Fontana's eudiometer had been shaken for a long time with water. The small basins are covered with a light film of sulphur, deposited by the sulphuretted hydrogen in its slow combustion in contact with the atmospheric oxygen.

Several experiments, made by means of nitrous gas in the narrow tube of Fontana's eudiometer, seemed to prove that the air of the crater contained 0.09 degrees less oxygen than the air of the sea; but I have little confidence in this result obtained by means which we now consider as very inexact.

But he did affirm that in midsummer, the mercury in the tube scarcely ever gets below 100° Fahrenheit, and the action of the sun's rays upon the stagnant water before-named, gives such an intimation to the nostrils of the state of the atmosphere, as to render the use of the eudiometer unnecessary.
