In a recent paper C. Palache and L. H. Bauer1 record the discovery of the presence of beryllium in vesuvianite from Franklin, New Jersey. This observation is of great interest, not only because it suggests possibly a new source of supply for beryllium, as was pointed out by the authors, but it also simplifies the chemical formula of vesuvianite, which has been more or less uncertain. In addition, this discovery indicates the importance of determining beryllium in various silicate minerals in which it has not been previously looked for or its presence suspected. In the ordinary course of silicate analysis beryllia (BeO) is precipitated with and weighed as alumina (AI2O3), unless it is separated from this constituent, which demands a somewhat complicated procedure. Indeed, the authors say: “It seems highly probable that beryllium is generally present in this mineral [vesuvianite] but has not been recognized, being determined as alumina.”
