In my view, the Christian religion is the most important and one of the first things in which all children, under a free government ought to be instructed... No truth is more evident to my mind than that the Christian religion must be the basis of any government intended to secure the rights and privileges of a free people. Preface to 1828 Dictionary

HYDRAUL'ICS, n. The science of the motion and force of fluids, and of the construction of all kinds of instruments and machines by which the force of fluids is applied to practical purposes; a branch of hydrostatic.
Hydraulics is that branch of the science of hydrodynamics which treats of fluids considered as in motion.
That branch of science, or of engineering,
which treats of fluids in motion, especially of water, its action in
rivers and canals, the works and machinery for conducting or raising
it, its use as a prime mover, and the like.
* As a science, hydraulics includes hydrodynamics, or the principles of mechanics applicable to the motion of water; as a branch of engineering, it consists in the practical application of the mechanics of fluids to the control and management of water with reference to the wants of man, including canals, waterworks, hydraulic machines, pumps, water wheels, etc. Some writers treat hydraulics and hydrostatics as subdivisions of hydrodynamics. | ||||||||
