Note. — The double observations shew a variation in the resistance at the same velocity of which the cause is to be found in theiftl* 

 given velocity its height is small, and the resistance is also small ; but when the velocity has been acquired by small increments due 

 and the resistance arising from it is also increased ; thus in the vicinity of the wave, and immediately behind it, the history of the 

 tions.
