FOWLER As a matter of fact there was a slightvariation from the specifications both bythe standard brasses of the railroad com-pany and those treated with titanium, butnot enough to cause any difference in therate of wear because of composition. The brasses supplied by the railroadcompany will be designated as the Stand-ard and those treated with titanium asthe Titanium-Treated. The composition of the two lots wereas follows: eight had been treated with 8 oz. of cupro-titanium per 100 lbs. or per cent, andeight with 12 oz. or per cent, byweight. This was enough to equip four cars,two with each percentage of titanium-treated and all four with the regular stand-ard brasses. The cars were the closed car carried on twobogie trucks and weighing about when empty. Add to this 6,000 the approximate average weight of the.
