Laboratory Examination of Special Rails This group is, at present, represented by the single form shown in Fig. is used for making check analyses against the mill analyses and for reporting theresult of chemical analysis and physical test of special rail or other test pieces whichmay be sent to the laboratory, from time to time, for examination. Fig. 349 showsstandard locations of borings for chemical analyses and also the standard tensiletest pieces of the association.

Compilation of Results for Study This group, Figs. 350-354, exhibits the different ways for compiling quan-titative statistics of rail failures. M. W. 408 (Fig. 350) is intended for compiling the information relative torail failures for a period of one year. The columns for specified chemical analysis are intended for recordingthe analysis of the particular lot of rail as given in the specification, and isinserted in this blank in order to give an idea as to whether the rail is high orlow in carbon, or high or low in phosphorus, etc. M. W. 409 (Fig. 351) has been provided on which the results from M. will be
