I. Harmonies of Lockyer's " Basic Lines." 



From the third law of motion it follows, as a necessary consequence, 

 that cosmical and molecular bodies act and react upon one another in ac- 

 cordance with laws of perfect elasticity. Hence, by introducing formulas 

 of undulatory motion, results can often be speedily reached which would, 

 otherwise, require the use of long and difficult analytical processes. 



In previous communications I have shown : 



1. That some of the most striking indications of nodal aggregation in 

 the planetary system, are connected, by the laws which govern the relations 

 between density and altitude iu elastic atmospheres, with the nodal indi- 

 cations of the Fraunhofer lines.* 



2. That the collisions of subsiding particles, from opposite diametral ex- 

 tremities of a condensing spherical nebula, tend to form shells or rings of 

 nodal aggregation, at g of the radial distance from the centre of the 

 nebula .f 



3. That centres of linear and of spherical oscillation, exert an important 

 influence, both upon molar and upon molecular arrangements. J Professor 

 Stephen Alexander had previously pointed out some instances of the re- 

 sults of spherical oscillation in the solar system. 



4. That the nodal resistance of large cosmical bodies tends to form other 

 nodal aggregations, at harmonic intervals, in accordance with the laws of 

 musical rhythm which govern the vibrations of elastic media. ^ 



5. That there are reasons for anticipating, in the fundamental oscillations 

 of terrestrial elementary bodies, symmetrical harmonic evidences of the 

 same laws as govern the harmonic nodes of elastic media and the har- 

 monic grouping of planetary systems. | 



I have also shown, both from independent considerations aud as corol- 

 laries from the foregoing laws : 



6. That in paraboloidal aggregation,*^ there are three wave systems, with 

 tendencies to nodal collisions and orbital aggregations in which the major 

 axes have successive differences of 4 x .
