Published between 1839 and 1852, this two-volume work records the contribution of William Scoresby (1789–1857) to magnetic science, a field he considered one of 'grandeur'. The result of laborious investigations into magnetism and (with James Prescott Joule) electromagnetism, Scoresby's work was particularly concerned with improving the accuracy of ships' compasses. A whaler, scientist and clergyman, he epitomised the contribution which could be made to exploration and science by provincial merchant mariners - men often less celebrated than their counterparts in the Royal Navy or in metropolitan learned societies. In addition to his pioneering work on magnetic science, Scoresby furthered knowledge of Arctic meteorology, oceanography and geography. Volume 1 considers the magnetism of steel and suggests ways to determine its quality and hardness.

The determination of the quality of bars, plates, or instruments constructed of steel; 8. Inferences, from these investigations; Part II: 1. As to the powers of combinations of magnetized plates of tempered steel in contact; 2. On the powers of combinations of magnetized steel plates separated by limited spaces; 3. On the relative powers of combinations of magnetized steel plates or bars; 4. On the relative powers, in combination or separately, of hard plates or bars of steel; 5. On the magnetical powers of steel plates; 6. On the effects of the annealing of hard steel plates; 7. On the powers of hard steel bars combined in various ways; 8.
