To find the points where the original values will exist, these 

 equations indicate that the density after this contraction, will 

 have its initial value at a distance 2/2. The initial pressure 

 will be found at a distance 4i?. 



The weight of a gramme, g, will have the initial value at a 

 distance 4i?. The mass internal to the point considered will 

 have the initial value at a distance ^H. In these last equa- 

 tions the variables p and JR are entirely independent.
