It was for the purpose of remedying these great and numerous defects thatMr. William Cubitt, whom we have already mentioned, instructed Messrs. Kan-some and May, skilful engineers at Ipswich, to try some experiments, from which 56 Fig. 1. certain improvements have resulted, which we are about to describe, and withwhich, through the kindness of Messrs. Manby, brothers, we are well acquainted. The chair represented in Figs. 1, 2, and3, is that employed on the South Eastern Rail-way, and of a new pattern. The points of re-sistance, and the edges are placed in such amanner as to give the chair all the solidity andstrength requisite without unnecessarily in-creasing its weight. A rim, c. Fig. 2, whichpartly covers the wedge B, has been so disposed,as to fix the rail immoveable in the chair. Asit is of the highest importance to jirevent allrising of the rail, the rim, c, of the intermediatepoint is prolonged in the joint chairs, as shown Fig. ;i
