62 neglected in the computations, and in order to inalce the reaultcas uniform as possible, the average of the load observed beforethe series of observations and that after the observationswas used in computing the unit stresses. In T7orXing up theresults of the first test made, that of 2050, the load v.a3 correct-ed for each observation by considering that the decrease v;asuniform during the time of making the observations, and theunit stress was computed to the nearest five pounds per squareinch for each gauge-line. The variation from the mean in anyone series was so small, rarely over fifteen pounds per squareinch, that in the other tests the average unit stress for thewhole series was used in plotting the results. 11, ComTDutation of Observations.-The procedure in talcingand computir^g the readings of a test is explained in the foll07;ingdiscussion. Readings were telcen first on two distinct pl&.ceson the standard bar. Each standard bar was used by one observeronly, hence the
