That these differences are really owing to the influence of the 

 seasons may be inferred from the excellent agreement of the four 

 total annual means, which are -0227, '0246, -0205, -0214. And 

 we may reasonably conclude, by the analogy of my observa- 

 tions, that, had the true hours of tides been observed, the order 

 in intensity would have been the same. The best observations 

 in other parts of the globe, afford us, it must be admitted, some- 

 what anomalous results. In the excellent observations of MAR- 

 QUE VICTOR, at Toulouse, little or no difference from the in- 

 fluence of the seasons was observed f . At Clermont Ferrand the 

 admirable observations of RAMOND assure us that the maximum 

 oscillation occurs in spring, and the minimum in winter |, with 

 a secondary maximum and minimum in autumn and summer. 



* For part of those for 1830, I am indebted to Mr HUDSON, the observer, whose 

 zeal in the examination of this phenomenon promises soon to afford us new and va- 

 luable data.
