LESINOF THE NEBULAR HYPOTHESLS (ole) 
The mass of the Martian ring was three hundred-thousandths 
of I per cent. of its nebula, and yet it took away 0.35 per cent. 
of the moment of momentum of the nebula. 
The mass of the Terrestrial ring was less than a third of a 
thousandth of 1 per cent. of its nebula, and it carried away 2.4 
per cent. of the nebular moment of momentum. 
The mass of Venus’ ring was about one fourth ofa thousandth 
of I per cent. of its nebula, and it carried off 1.89 per cent. of 
the nebular moment of momentum. 
The mass of the Mercurial ring was only about one fifth of a 
ten-thousandth of 1 per cent. of its nebula, and it hypothetically 
carried off 0.12 per cent. of the nebular moment of momentum. 
Not only are these ratios very extraordinary in themselves, 
but their relations to each other seem scarcely less remarkable. 
This will appear more apparent when they are gathered into a 
table and referred to a common unit. This unit is one one- 
hundred-thousandth of I percent of the individual nebular 
mass. It will be seen that on this proportional basis, the moments 
of momenta range through a gamut of more than ten points, 
the proportion of Mars being more than ten times that of its 
neighbor Jupiter.

There seems to be no systematic variation in these. It is 
furthermore remarkable that, high as is the ratio of Jupiter’s 
moment of momentum to the parent nebula, it is proportionately 
surpassed in most other cases. 
4. Can these high ratios of the moments of momenta of the planets 
to the residual nebule be attributed to transfer of moment of momentum
