%* This work contains a vast number of different hydraulic 

 formulas, and the most extensive and accurate tables yet published 

 for finding the mean velocity of discharge from triangular, quadri- 

 lateral, and circular orifices, pipes, and rivers ; with experimental 

 results and co-efficients ; effects of friction ; of the velocity of 

 approach ; and of curves, bends, contractions, and expansions ; the 

 best form of channel ; the drainage effects of long and short weirs, 

 and weir-basins ; extent of back-water from weirs ; contracted 

 channels ; catchment-basins ; hydrostatic and hydraulic pressure ; 

 water-power, &c. &c.
