I take my hat off to Faraday for having the courtesy to reply. I suspect that he was showered with nonsensical letters.
Michael Faraday, FRS (1791–1867) was an English chemist and physicist who contributed to the fields of electromagnetism
and electrochemistry. Faraday was the first Fullerian Professor of Chemistry at the Royal Institution.
A Manual of Electricity, Magnetism and Meteorology by Dionysius Lardner, edited and completed by Charles V. Walker,
was published in 1844 as part of the Cabinet Cyclopaedia series.
