A collection of Kelvin's scientific lectures on the science of the seas, particularly on navigation, tides and magnetic forces.William Thomson, Baron Kelvin (18241907), was one of the most important Victorian scientists. These volumes collect together Baron Kelvin's lectures for a wider audience. Volume 3, published in 1891, deals with the science of the seas and oceans, particularly as it relates to navigation, tides and magnetic forces.William Thomson, Baron Kelvin (18241907), was one of the most important Victorian scientists.

While only in his twenties, he was awarded the University of Glasgow's chair in natural philosophy, which he was to hold for over fifty years. He is best known through the Kelvin, the unit of measurement of temperature named after him in consequence of his development of an absolute scale of temperature. These volumes collect together Kelvin's lectures for a wider audience. In a convivial but never condescending style, he outlines a range of scientific subjects to audiences of his fellow scientists. The range of topics covered reflects Kelvin's broad interests and his stature as one of the most eminent of Victorian scientists. Volume 3, published in 1891, deals with the science of the seas and oceans, particularly as it relates to navigation, tides and magnetic forces.Preface; 32. Navigation; 33. The tides; 34.
