Raoul Pictet and Liquefaction of Gases

Hello, I believe you will find that Raoul Pictet actually liquefied oxygen, not nitrogen. Liquefaction of nitrogen was achieved later by Olszewski and Wroblewski in Poland. No sources at hand now though, except what can already be found on wiki, sorry.147.173.53.130 (talk) 20:33, 19 June 2011 (UTC)[reply]
