[The work of Carl Wilhelm Scheele]. / Ergänzungen zu den Kenntnissen und Meinungen über das Werk von Carl Wilhelm Scheele.

On the occasion of C. W. Scheele's 200th anniversary of death corrections and complements to some of his important investigations and theories including discussions of priorities, are given to elucidate his works and to avoid misunderstanding (element term; tartaric, oxalic and benzoic acid; pyrolusit; earths/spar/Bologneese luminous stone/barite; Scheele/Bergman/Lavoisier; fire theory/discovery of oxygen; graphite/Wolfram; Scheele/Wenzel).

[News of the discovery of acids in organic material by C.W. Scheele (author's transl)]. / Neues über die Entdeckung von Säuren in organischem Material durch C.W. Scheele.

With reference to a critical publication by F. Ehrhardt (1780), the author presents and analyses all documents concerning the discovery of tartaric, oxalic and phosphoric acids in animal earth (from bones or hartshorn, Cornu cervi). Furthermore, he dates Scheele's manuscripts Nos 22 to 41 from Oseen's collection, and draws conclusions as to Scheele's studies on fluorspar and to Scheele's acquaintance (1770) with J.G. Gahn and T. Bergman.
