Contenido:

A manual of the theory of the deviations and mechanical correction of magnetic compasses in ships.

In addition to dealing with the properties of magnets and the earth's magnetism, three chapters are devoted to the magnetism of the ship, the third explaining in detail the reason for, and composition of, the "nine rods". The relation of the components P, Q and R and the rods to the various coefficients are fully explained.

There are about 70 diagrams, a few in colour, to simplify the matter in the text.
