107 At an age of 50 days, corapresclon apeclnen 2050 vrac loaded toaboul. 950 lb. per sq.in. , and the test discontinued. The resultsof this preliminary test v;ere computed and it was foiind that theywere consistent although they show a smaller ratio of deformationon the cross to deformation on the arm than the later threetests. The ratio of deformation on the cross to that on the armaveraged 0.54 during the test. The difference between this andthe values obtained from specimens 2051, 2052 and 2053, testedapproximately 70 days after they were made, may perhaps beaccounted for by the difference in age. Two days after thefirst test, specimen 2050 was loaded again with a differentarrax:igement of apparatus. The results of the second test areshown in Fig. SI. The rather high values of 0.70 and 0.79 forthe ratio of deformation on the cross to that on the arm in thefirst two stages of the second test of 2050 may have been duepartly to Lhe earlier test. The apparent initial modulus ofelastic
