It has been proved by Newton , that a particle of matter ( N. 6 ) placed without the surface of a hollow sphere ( N. 7 ) is attracted by it in the same manner as if the mass of the hollow sphere , or the whole matter it contains ...

The whole force ( N. 63 ) which disturbs a planet is equivalent to three partial forces . One of these acts on the disturbed planet , in the direction of a tangent to its orbit , and is called the tangential force : it occasions secular ...

In what precedes , the influence of only one disturbing body has been considered ; but , when the action and reaction of the whole system are taken into account , every planet is acted upon , and does itself act , in this manner ...

But the mass of the whole of the planets and satellites taken together is so small , when compared with that of the sun , that these effects are quite insensible , and could only have been discovered by theory .
