Reminder how, on the 8th of April 1503, I, Leonardo da Vinci, lent to Vante the miniaturist 4 gold ducats in gold; Salaì carried them to him and gave them into his own hand. He said he would return them to me within the space of 40 days.

Reminder how, on the above-said day, I gave back to Salaì 3 gold ducats, which he said he wished to use to make himself a pair of rose-coloured hose with their trimmings. And I am still left owing him 9 ducats, granted that he owes me 20 ducats, that is, 17 lent at Milan and 3 at Venice.

Reminder how I gave Salaì 21 braccia of cloth to make shirts, at 10 soldi the braccio; which I gave him on the 20th of April 1503.

Although the percussion of the moving body upon its object can be caused by equal powers, it does not therefore follow that their powers are not variable to infinity.

Even though moving bodies are equal and are brought to the site of percussion with equal distance and power, it does not therefore follow that such percussion is not, in itself, variable to infinity.

The percussions made upon one and the same object can be variable to infinity, even though they arise from the same impulses and from the same moving bodies moved through equal distances.

Although the percussions are created upon one and the same object, and by the same power of impulse, and by equal moving bodies moved through equal distances to the site of percussion, it does not therefore follow that their powers cannot be variable to infinity.
