To quickly assess the difficulty of the text, read a short excerpt:
) The concentration of the copper salt was constant throughout, and equal to 0. 05 normal. The percentages of water in the solutions, beginning with the one whose spectrum is adjacent to the numbered scale, were 0, 4, 8, 10, 12, 14, 16, 18, 20, 24, 28, 32, 36, 40, 44, and 50. The depth of the absorbing layer was constant and equal to 2. 0 cm. The solution containing no water was brown, and practically opaque in deep layers. With addition of water the color changed rapidly to yellow- ish-green, ...and finally became bluish-green in the solutions containing the greatest amount of water. The time of exposure to the light of the Nernst lamp and spark was, respectively, 1 and 3 minutes, the slit having, as usual, a width of 0. 01 cm. The limits of transmission for the first eight solutions, beginning with the one containing no water, were A 5450, A 4900, A 4625, A 4520, A 4450, A 4330, A 4270, and A 4220. Leaving out the first two, where there was considerable general absorption, the limits fall almost exactly on a straight line.
