11. In 1898 he was a delegate to the International Conference on Terrestrial Magnetism , which was held at Bristol, England. 12. The commander was J . F .

From 1951 to 1971, he was a staff member at the Carnegie Institution of Washington, Department of Terrestrial Magnetism . 14. Simultaneously, he worked on terrestrial magnetism , and magnetic charge of the geological expeditions in the vicinity of Mount Elbrus. 15. This was the paper rejected by the U . S . journal " Terrestrial Magnetism and Atmospheric Electricity ". 16. According to Father Serafim Leite, the Jesuits installed an observatory in his school in Castle Hill in the terrestrial magnetism . 17. In 1819 he published a volume of researches on terrestrial magnetism , which was translated into magnetic poles of the Earth. 18. The magnetic observations he made during his travels were utilized by Carl Friedrich Gauss in his theory of terrestrial magnetism . 19. Much of the increased activity and interest in hydrography, geodesy, seismology, and terrestrial magnetism may be traced directly to his influence. 20. In 1859 he was appointed director of Kew Observatory, and there naturally became interested in problems of meteorology and terrestrial magnetism .
