This selection concludes the series of abstracts on work published some years ago. The special subject index to abstracts in this issue combines all abstracted matter in-this volume. The classification deviates slightly from that used for the Systematic hbstracts 19.57. N’ithin each sub-group the Abstracts are systematized alpha~ticall~. (Ed.)
Some Recent Experiments in Friction. F. P. Bowden. ,vature, v. $76, Nov. 19, 1955, P. 944-946. Measurements of friction and wear on C‘n and Bi at sliding velocities up to 1000 m per sec. Graph, diagram, micrographs. The Adhesion of Clean Metals. F. P. Bowden and G. W. Rowe. Royal Society, Proceedings, v. 233, ser. A, Jan. IO. 1956, P. 429-442. Investigation of adhesion between surfaces of hard metals cleaned by heating in a high vacuum. I,ow initial adhesion is due to released elastic stresses when load is removed. Application of tangential force in addition to load increases adhesion. Diagrams, graphs, table. 14 ref. Friction in a Close-Contact System. ttTalter Claypoole. A6echa42ical ~~g~~eey~ng, v. 78, June 1956, p, 529-332. Fundamental aspects of problem and experimental evidence supporting new inferences with regard to friction.

Tt, Jan.-Feb. 1956, p. 50-58: disc., p. 58-5.9. Comparative friction behavior of 7.5 couples and the role of atmosphere in the sliding process were investigated.
