Abstract
The two Topaz samples do not contain Be, as was shown by the absence of characteristic beryllium lines in the ultraviolet spectrum of these minerals,
The sample of Beryl probably containers 10% or less BeO, instead of the 14% as indicated by the Parsons and Barnes method of analysis.
Al(OH)₃ is appreciably soluble in the boiling NaHCO3 and the repeated reprecipitation produce a very questionable degree of accuracy in the separations.
