Labels:text | screenshot | font OCR: On 26r Leonardo describes a number of practical applications of the theoretical study of water pressure, particularly as it applies to swamp drainage. Here, as elsewhere, he lists a number of "cases" -in this instance, 18-to be examined in the future. Leonardo begins the page with directions on how to empty a swamp by means of "siphonic action" A and ends with a sketch describing the weight of water in a cylindrical container B upon which he has marked off measurements similar to those on a modern measuring cup.
