![Codex Leicester, 32v. - Page without figures, containing observations on watercourses and on physical geography. On the lower part of the sheet Leonardo discusses subjects pertaining to the presence of water on mountains, which is not drawn there by the heat of the sun. The earth does not act "like a sponge"; it is not true that the water in the sea, far from the shore, is as high as the mountains. Writes Leonardo: "The water found in the highest mountains is not there because it was drawn up by the sun, because little of such heat arrives there, as can be seen below La Vernia, the force of the sun being insufficient to melt the ice in the greatest heat of summer; on the contrary, the ice remains stored in the caverns where it was placed at the end of winter [...]".](https://vitruvio.imss.fi.it/foto/isd/av/lei_32v_300.jpg)

![Codex Leicester, 34v. - "There are two centres of sphericity of water: one is that of universal water, the other is particular. Of the universal kind is that which serves for all of the waters without motion, which make up a great quantity, such as canals, ditches, fish nurseries, springs, wells, dead rivers, lakes, swamps and seas; the which, although they are all of different heights, have surfaces that are equidistant from the centre of the world, as in the lakes found at the tops of the highest mountains, like the one on Pietra Pana, and the lake of the Sibilla, a Norcia[...]". The mountain of "Pietra Pana", mentioned also by Dante, is Pania della Croce, in the Alpi Apuane; it has an altitude of 1,858 meters above sea level. Today there is a mountain shelter, the Rifugio Pietra Pana, at an altitude of 1,180 m.](https://vitruvio.imss.fi.it/foto/isd/av/lei_34v_100q.gif)
