OF THE NATIONAL PHYSICAL LABORATORY, TEDDINGTON. During the years 1904-1905 the authors were engaged in a research on the resistance of certain kinds of iron and steel to reversals of direct stress.* I n these experiments the change from tension to compression was gradual, and followed an approximately simple harmonic law, special care being taken to avoid the subjection of the specimens to sudden shock, the effect of which, it was considered, would complicate the problem, and might

Since in ordinary machine practice the stresses induced in the moving parts are, in general, due to a combination of shock and gradually applied load, as might happen in the case of the crank-pins and bearings of reciprocating engines, it appeared to the authors that the determination of the relative resistances to sudden shock of the same materials as used in the previous work on gradual reversals of stress would, combined with the previous results, be of considerable value to the designer. This determination appeared to be the more urgently required, since in the opinion of engineers of such wide
