. American engineer and railroad journal . .12 in. in Inches. Inches Inches Inches Inches Inches 7 21 1 1 ( 10 13 1 (* 1 1 1 •• Total increase)in diameter. / circular cross-section of the jet had been changed into an ellipse bythe bridge, into which the longer axis lay at right angles to thebridge. jjig. 66 shows such a section of the jet by the cross-hatchet linesfor a height of inches. The outer circle shows the ring usedfor the measuring; the dimensioQs given are those from which theaxis of the ellipse were located. It is thus seenhow the wedge-shaped surface of the bridge causesthe steam to make a sharp deflection at right angles to its length,while in the direction of its axis there is a smaller variation from thecircular section that is quite noticeable, as is shown in Table XXVI, TABLE
