American chemical journal . Moist Phosphonis and Air and Carbon Monoxide. 427 Baumanns experiments, and the gases, after passing out of theozonising vessel, were washed with a rather larger quantity ofwater than was used by Baumann. A cloudiness began to appearin the baryta water after six or eight litres of air had passedthrough, and this increased constantly, until when 25 to 30 litreshad passed in 12 to 15 hours a distinct precipitate, not a mere tur-bidity, was in the vessel containing the baryta water. The precipi-tate was carefully examined with reference to the presence of phos-phorus compounds, but not a trace could be detected. The expe-riment was repeated with the same result. It is clear, therefore,that in spite of Baumanns explicit statement, there is some sourceof carbon dioxide independent of carbon monoxide, and beforeaccurate experiments can be made this source must be discoveredand if possible avoided. Karsten has shown that when air alone comes in contact withthe organic matter of corks and con
