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. This publication has a great deal of hitherto unpublished information.
