Page 55 - ... although one clause of a sentence in it, read by itself, might be supposed to do so. The passage is to be found in their work at p. 286. They begin by saying, that their experimental observations detailed in their previous pages " prove that even in a perfectly calm day there is a strong resistance to the motion of the water at the surface as well as at the bottom," and that this resistance at the surface " is not wholly or even mainly caused by friction against the air.
Page 4 - The rise of ordinary floods is from 5 to 7 feet in 24 hours only, and the maximum is 50 feet above coldweather level.
Page lvii - ... rivers and canals in bad order and regimen, overgrown with vegetation and strewn with stones or detritus of any sort.

The Viranam tank, a very ancient work, in Tanjor, has an area of 35 square miles, and an embankment 12 miles long; it is still in full operation, and secures an annual revenue of £ll 453.
