A method for drying the marsh of Piombino. [Footnote: There is a slight sketch with this text in the original.—Piombino is also mentioned in Nos. 609, l. 55-58 (compare Pl. XXXV, 3, below). Also in No. 1035.]

The shepherds in the Romagna at the foot of the Apennines make peculiar large cavities in the mountains in the form of a horn, and on one side they fasten a horn. This little horn becomes one and the same with the said cavity and thus they produce by blowing into it a very loud noise. [Footnote: As to the Romagna see also No. 1046.]

A spring may be seen to rise in Sicily which at certain times of the year throws out chesnut leaves in quantities; but in Sicily chesnuts do not grow, hence it is evident that that spring must issue from some abyss in Italy and then flow beneath the sea to break forth in Sicily. [Footnote: The chesnut tree is very common in Sicily. In writing cicilia Leonardo meant perhaps Cilicia.]
