Title: [N322000B] Technical Note, c. 1886
Editor's Notes: 83 1/2 H 142 8/10 H 179 5/10 H 125 8/10 Carbonic acid CO2 109 2/10 CO2 95 CO2 A spectrum of a tube taken off of a washed Hydrogen pump. No spark having passed through it. Another gauge on the same pump which has sparks pass trhough it several houres, showed no carbonic acid. This shows that carbonic acid or organic matter was either on the magnesium electroes or on the glass. These readings were gotten by making the slit for each line very fine, reading from the left-hand edge and focusing both the scale and the scope for each line. The width of the line I have called 2/10 of a degree.; Supplied year
