The tests on the other two engines were carried out in 
very much the same manner, and therefore need no further 
description. A table comparing the per cent. distribution 
of friction in the three engines is given. Those values are 
compared in the table which were determined at the speed 
nearest to the normal running speed of each engine, though, 
as will be seen from the previous table, the relative dis- 
tribution does not vary very much with variation in the 
speed.
