A cross current could only curve the free part of the ae re

we recur to theidea of the cable lying upon the supposed inclined tess 
surface; for although we made it curve in any manner by pressing 
against it sideways, it would, as before, be prevented from slipping het 
by the weight of a portion of the same cable, whose length was th 
pendicular height of the plane. 
I may just remark, that if the ship moved with an accelerated velocity, 
the cable would form a curve with the convexity upwards, and on the 
other hand, if she moved with a achat rae the cable would form
