Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility.

The results are contained in a short paper in the Quarterly Journal of Science, Vol. XV. Its composition is very nearly chlorine, water, or 1 proportional of chlorine, and 10 of water.
