1. Heats of adsorption of Congo Red and Fuchsine by various samples of hydrous thorium oxide have been calculated.

2. Bromine - Bromine - Analysis: A sensitive test for Bromine is the reaction with fluorescein to give a deep red colour caused by Bromination of the organic molecule, or by its reaction with fuchsine dyes in the presence of sulfurous acid, to give a deep blue colour
