169. Alternate conjunction and opposition of the solar tides and 



the annual tide ... . .10 



170. Conflict of these forces at the periods of the equinoxes . 11 



171. Conflict of the same forces at the periods of the solstices . 12 



172. The conflicts of the June solstice and the September 



equinox occur in the northern hemisphere ; those of 

 the December solstice and March equinox in the 

 southern hemisphere ... . 12 



173. Action of the opposing forces . . ... 13 



174. That these periods of conflict are in accordance with what 



experience has shown to be the stormy periods in each 

 hemisphere respectively . . . . . .13 



175. That if not interfered with by other forces, the conflicts 



between the solar tides and the annual tide would be 

 similar each year, and recur on the same days each 

 year. ......... 14 



176. Oscillations in latitude of the lunar tides will alternately 



retard and accelerate the ebb and flow of the annual 

 tide 16 



177. That similar influences of tidal oscillations in latitude recur 



in cycles of 149 years . . . . . .16 



178. That the recurrence of similar storms is dependent on the 



recurrence of similar positions in longitude, which do 

 not recur in the cycle of 149 years . . . ,18 



179. That the lunar tides will at times neutralise, and at other 



times intensify, the conflicts between the annual tide 

 and the solar tides. And have also themselves periods 

 of independent conflict with those tides . . .19 



180. Action of lunar forces at the various epochs of conflict . 20 



181. That the currents reported at Bhering's Straits are in 



accordance with the theory under consideration . . 23

OSCILLATIONS OF THE BAEOMETER. 



182. That the arguments hitherto adduced do not determine 



the relation which the forces which raise the annual 

 tide bear to those which raise the solar and lunar tides 25 



183. That, apart irom the difference in the height of the water^ 



the intrinsic difference in the nature of the attraction
