Abstract
IN 1914, when chemists found themselves deprived of the usual Continental supplies of laboratory reagents, a joint committee appointed by the Institute of Chemistry and the Society of Public Analysts drew up specifications to ensure a sufficient degree of purity in eighty-eight chemicals of importance in analytical work. Reagents of this quality were distinguished by the letters “A.R.”. This useful action was taken merely as a War-time emergency measure, and has not been continued by the two societies.
