Marie Curie papers

Under Section "Publication by Marie Curie" I did a quick overview of the papers in which Marie Curie and collaborators publish the existence of new elements polonium and radium. Both are very understandable (except the chemistry), and have some cute terminology. I also cited those papers on her Wikipedia page: en.wikipedia.org/w/index.php?title=Marie_Curie&diff=1240252528&oldid=1238097626 Another good exercise in "old paper finding" + "Wikipedia markup/rules" as I looked at the Comptes rendus de l'Académie des Sciences a bit.
