The general results of these two experiments are placed in juxtaposition 

 in the following table : — 



It appears, therefore, that the difference in the whole distance run by the 

 two coaches and by the engine and tender, amounted to only 133 yards in a 

 distance little short of three miles ; and there was only three seconds differ- 

 ence in the time which elapsed between the moment of starting and the mo- 

 ment of coming to rest. The maximum speed was the same, and the times 

 of descending the inclined plane differed by only five seconds. The differ- 

 ence, such as it was, was in favour of the coaclies. In fact the differences 

 of the numbers in the successive columns are only sucli as woidd take place 

 in the same experiment twice repeated with the same coaches. 



As a further experimental test of this point, the engine and tender were 

 now placed in front of a train of four coaches, and were allowed to descend 

 the plane in the same manner. The engine and tender were tlien removed, 

 and replaced by two coaches of equal weight, and the train of six coaches 

 was allowed to descend the plane in the same manner. The details of these 

 experiments are as follows: —
