nuary, February, March, and April are also reversed, being 4 to 6, instead 

 of 6 to 4. 



When one decade is compared with the other, the last-named months 

 are found to stand in exact inverse order, viz. 6 to 4 in the first, and 4 to 

 6 in the second. 



The wet and dry groups seem, on the whole, to be more evenly balanced 

 than the warm and cold ; but the Novembers of the second decade are 

 remarkable for dryness. The connexion between the predominant winds 

 and the other states of weather has not as yet been traced systematically ; 

 but the diagram shows great excess of north-east wind in the spring of 

 18.52, and a long continuance of cold weather setting in early in the fol- 

 lowing year. It is also evident that wind from south-east was more pre- 

 valent during the second than the first decade. 



From the foregoing comparison of the different months, the group of 

 Novembers seems to be the most exceptional ; it may therefore be worth 

 while to recapitulate the peculiarities that have been noticed. 



1st. The ratio between the coefficients of this group in different decades 

 is invariably one of considerable inequality. 



2nd. Two cold Novembers only occur in the warm cycle, and only two 

 warm ones in the cold cycle. 



3rd. In the second decade the proportion of warm to cold Novembers 

 is 8 to 2, and of dry and wet 2 to 8 ; but in the warm period warm and 

 wet months were prettily evenly distributed. 



4th. Novembers of comparatively low temperature, such for instance as 

 those of 1851, 1853, 1854, 1855, 1856, 1860, 1861, and 1862, were in 

 each year succeeding those enumerated, followed by Mays or Junes of a 

 similar character. The following resume shows the relations between the 

 Novembers and the Junes.

These contrasts and analogies seem to justify the surmise that the at- 

 mospheric conditions of the former months may have exercised some in- 

 fluence upon those of the latter. Whether such be the case generally is 

 not to be determined until a much longer series of results at Guernsey can 

 be compared. 



The pecuharities with respect to the Novembers may be purely acci- 

 dental, or confined to the period under consideration ; but that they are
