tlic experimental error is inflated tenfold. The assignable causes found in 

 the previous experiment are found here, where measured, with one 

 exception — ^ the interaction of Codes on Positions. The estimate of a' 

 for a single reading with the card support bars out now becomes 



a' = 8.56 ms. 



Since the overall estimate of mean dropping time with the card support
