A4Y1, Sun’s Hquatorial Acceleration. 
The luminous projection of Jupiter and of the centre of the dense belt, as 
well as the other evidences of apsidal influence upon planetary harmonies, 
show that molecular ods viva has slightly modified the simple undulatory 
vis viva of the luminiferous ether, The amount of the solar equatorial 
acceleration ig not precisely known, because no Sun-spots have been ob- 
served very near the solar equator ; it cannot, however, differ much from 
Earth’s mean secular eccentricity, We may, therefore, regard this as 
another evidence of the harmonic importance of ‘subsidence ’’ to the belt 
of greatest density.
