Chemical/alchemical work (p. 1-154), preceded by an explanation of astronomical and chemical symbols and by a table of contents (p. [vii]-[xii] before p. 1), to which page references were added by the same hand that added the pagination. Begins (p. 1) with a chapter on "lapis philosophorum" and continues with astrological, alchemical and pharmaceutical sections, e.g. Sole di Fra Giorgio d'Armenia; sole in mercurio; lavoro mercuriale; oglio d'antimonio' sale di vitriolo; purificatione di mercurio; ad morbum gallicum. Also includes a litany of the Blessed Virgin (p.158-159), very similar to the Litany of Loreto.
