and vis inertiae tides concomitant with motion should be 

 more or less apparent both in the ocean and the atmo- 

 sphere . . . 2G 



184. That, as regards the motion of the earth with the solar 



system through space, the difference in the nature of 

 the tides concomitant with that motion is apparent in 

 the lower average height of tire barometer in the south- 

 ern than in the northern hemisphere ; and that, as 

 regards the motion of the earth in its orbit, the analo- 

 gous effect on the barometer, caused by the tides 

 concomitant with that motion, is apparent in the annual 

 oscillation of the barometer . . . . .26 



185. That an accurate analysis of the oscillations of the baro- 



meter will show the relation which the velocity of the 

 earth's motion southward bears to the velocity of its 

 motion in its orbit ....... 30 



186. That the diurnal oscillations of the barometer result from 



the action of the opposing forces of solar and astral 

 gravitation ........ 31

OCEANIC LEVELS. 



187. Relative levels of the waters adjacent to the Isthmus of 



Suez 38 



188. Relative levels of the waters adjacent to the Isthmus of 



Panama ......... 39 



189. That the levels observed about the Isthmus of Panama 



accord with the theory of a southward motion of the 

 solar system through space . . . . .42
