NEW LIST OF STANDARD SAMPLES.

A new list of standard samples for use in chemical analyses has just been published by the bureau as Supplement to Circular No. 398.

This replaces the former list known as Supplement to Circular No. 25.

The samples are listed by groups, such as irons and steels, ferro alloys, sheet brass, bronzes, bearing metals, die-casting alloys, limestone, clays, glass sand, various kinds of glasses and ores; sugar, naphthalene and benzoic acid for determining heats of combustion; cement for testing the fineness of sieves; and pure chemicals, such as sodium oxalate, arsenic trioxide, and acid potassium phthalate.

Directions are given for ordering and the methods of shipment to addresses in the United States and foreign countries are described.

Copies of this pamphlet are obtainable without charge from the Bureau of Standards, Washington, D. C.
