[Footnote:  1030 and 1031.  From the character of the handwriting we may conclude that these observations were made in Leonardo’s youth; and I should infer from their contents, that they were notes made in anticipation of a visit to the places here described, and derived from some person (unknown to us) who had given him an account of them.]

The lake of Pusiano flows into the lake of Segrino [Footnote 3:  The statement about the lake Segrino is incorrect; it is situated in the Valle Assina, above the lake of Pusiano.] and of Annone and of Sala.  The lake of Annone is 22 braccia higher at the surface of its water than the surface of the water of the lake of Lecco, and the lake of Pusiano is 20 braccia higher than the lake of Annone, which added to the afore said 22 braccia make 42 braccia and this is the greatest height of the surface of the lake of Pusiano above the surface of the lake of Lecco.

At Santa Maria in the Valley of Ravagnate [Footnote 2:  Ravagnate (Leonardo writes Ravagna) in the Brianza is between Oggiono and Brivio, South of the lake of Como.  M. Ravaisson avails himself of this note to prove his hypothesis that Leonardo paid two visits to France.  See Gazette des Beaux Arts, 1881 pag. 528: 

Au recto du meme feuillet, on lit encore une note relative a une vallee “nemonti brigatia”; il me semble qu’il s’agit bien des monts de Briancon, le Brigantio des anciens.  Briancon est sur la route de Lyon en Italie.  Ce fut par le mont Viso que passerent, en aout 1515, les troupes francaises qui allaient remporter la victoire de Marignan.

Leonard de Vinci, ingenieur de Francois Ier, comme il l’avait ete de Louis XII, aurait-il ete pour quelque chose dans le plan du celebre passage des Alpes, qui eut lieu en aout 1515, et a la suite duquel on le vit accompagner partout le chevaleresque vainqueur?  Auraitil ete appele par le jeune roi, de Rome ou l’artiste etait alors, des son avenement au trone?_] in the mountains of Brianza are the rods of chestnuts of 9 braccia and one out of an average of 100 will be 14 braccia.

At Varallo di Ponbia near to Sesto on the Ticino the quinces are white, large and hard.

[Footnote 5:  Varallo di Ponbia, about ten miles South of Arona is distinct from Varallo the chief town in the Val di Sesia.]
