Poiloiing vorde of Iabtti±b are also equally true. i'Ve Mow that upto the prep 1nt time our kn fledge of hydraulics is extremely halted pa i.... oul rly the River Uydrauhtcs, for although soon of great €eniuo have applied tbe.moclvca to the otudy of hydraulics at various times, co are as yet after many centuries in almost complete ignorance of the true la to which the flow of eater is e:ub, eet; it is scarcely a century and half since by Ceene of oxport-montotion the duratic:n , vohumo and velocity of die-charge of water through any kind of orifice ma d.iocovored".
