This notebook covers the period January-May 1890. It was used by Arthur E. Kennelly and Theodore Lehmann as a rough record book in the Galvanometer Room. The book contains notes, drawings, and calculations regarding battery tests; the use of hydrogen as a rust inhibitor for steel; the use of a phonograph motor for sewing machines; insulation experiments; measurements of the magnetic permeability of iron; and various other electrical experiments. Transcriptions of these records can be found in Arthur E. Kennelly Notebooks #2 and #3. Two pages of notes relating to an "Experiment on the Production of Electricity by passing Coal gas upon spongy Platinum" have not been transcribed. The front cover is labeled "#588." The spine is labeled "105." The book contains 189 numbered pages.
Only the notes on the coal gas experiment have been selected.
