The Influence of Nickel and Carbon on Iron.* — G. B. Waterhouse 

 has investigated the properties of a series of ten steels, containing about 

 3 • 8 p.c. nickel, the carbon varying from ■ 4-1 ■ 83 p.c. Cooling and 

 heating curves were taken, and mechanical tests and microscopic exami- 

 nation were made on the steels heat-treated in various ways. The 

 chief conclusions arrived at are — (1) nickel raises the tenacity of steel 

 without materially lowering the ductility : the elastic ratio is only 

 slightly greater than in carbon steels ; (2) cementite of the formula 

 FeJSTi 3 C occurs in these steels ; (3) the eutectoid ratio appears to lie at 

 about 0*7 p.c. C.
