The hazards inherent in sampling at sea for trace element analyses are discussed. It is proposed that a discussion be held at Helsinki in 1960 on:---- (a) sampling for trace element analysis; (b) a system for international exchange of samples and for reciprocal control of methods for analysis of trace elements.
