 a cord before them than when they make it pass over their 

 shoulders : it shows us also that the largest men have not 

 also the greatest strength to hold, or to draw in a horizontal 

 direction by means of a cord. To obtain the absolute velocity 

 of these twenty men, I proceeded as follows : 



Having measured very exactly a distance of 12,000 Rhin- Marching of

continue during the space of four or five hours. The following 



is the time employed in describing this space, with the velocity 



resulting from each of them. 



It is necessary to mention, with regard to these experiments, 

 that I took care to place, at certain distances, persons in whom 

 I could place confidence, in order to observe whether these 

 men marched uniformly and sufficiently quick without run- 

 ning.
