It is excentric as regards the pole and sends tapering extensions towards the south.
Here BB is a large fixed iron cylinder, corrugated within, and C an excentric cylinder, also corrugated, which, in turning to the right, by the friction of its corrugated surface rotates the puddled ball D which has just entered at A, so that, turning around its own axis, it travels to the right and is gradually changed from a ball into a bloom, a rough cylindrical mass of white hot iron, still dripping with cinder.
- Plan of Burden's piling and re-rolling, into the Excentric Revolving Squeezer final shape in which it is actually for Puddled Balls.
Thus for a circular orbit with the centre of force at an excentric point, the hodograph is a conic with the pole as focus.
As another Q~ example, suppose we have a circular cylinder whose masscentre is at an excentric point, ~- rolling on a horizontal plane.
