57. Stars will pass through such caps of nebula and will 

 be entrapped, and will attract nebulous matter, and will 

 become nebulous stars, or they may be volatilised altogether 

 and become globular nebulae. 



58. Where globular nebulce are thick we should expect 

 double, spindle, and spiral nebulae. These nebulse are actually 

 found amongst the nebulae at the polar caps of the Milky Way. 



59. Where stars are thick we should expect the result of 

 the impact of stars — such as planetary nebulse, temporary and 

 variable stars, double stars, and star-clusters. These are all 

 chiefly in the Milky Way. 



60. If the universe were formed by such a graze we 

 should expect a greater density of stars where the motion 

 chiefly directed the two original universes. There are two 

 such clustering masses. 



61. If the universe were the result of impact there would 

 be much community of motion in adjacent stars. This is a 

 remarkable peculiarity of the stars in the Galactic Eing. 

 Most of these agencies are debated in my paper " On the 

 Origin of the Visible Universe." 



62. Nebulse would tend to entrap bodies passing through 

 them. These bodies would become orbitally connected, and 

 when the nebula settled down to a sun the bodies would 

 produce a system with planets in all azimuths, in the same 

 way as the comets that our solar system has entrapped are in 

 all azimuths. 



63. Were such a body to impact with a similar one, or 

 with a sun, and were the gi'aze considerable, all the planets 

 would be spun roughly into a plane, and the central mass 

 would become a bun-shaped nebula. The agencies that would 

 convert this into a system similar to ours are discussed in my 

 pa^oer " On the Origin of the Solar System," and in the paper 

 "On Causes tending to lessen the Eccentricity of Planetary 

 Orbits." 



64. It can be shown that if two gaseous suns without 

 original proper motion impact completely, and were the 

 whole of the motion converted into heat and this into expan- 

 sion, the new sun would have a diameter the sum of the dia- 

 meters of the original suns. It can also be shown that this 

 condition is one of stable equilibrium. 



65. The complete impact of two suns brought together by 

 gravitation does not make a nebula of them, but as soon as 

 the paroxysm of the encounter is over they are of the same 

 temperature as before, and have only increased to the sum of 

 their original diameters. 



66. Were there great original proper motion they might 

 become a nebula by complete impact ; but were the impact of 

 great energy, then an infinitely diffused cold nebula would
