on the Eastern frontier along the base of the Himalayas, was felt 

 along the line of the Northern frontier from Dinajepore to Purneah ; 

 but not to so great an elevation as Titalayah, which is about i ,000 or 

 1,200 feet above the level of Calcutta, and 50 miles farther North than 

 Dinajepore. 



8. That on the 5th, there were also three distinct revolving storms, 

 one at Soorajegunge, over which a centre passed between 8 and 9 a. m., 

 and two others at Bhaugulpore and Jungypore, close to which centres 

 must also have passed. The Bhaugulpore one was not that of Cal- 

 cutta, and that of Jungypore may be supposed to be made up of this 

 last and the influence of the Soorajegunge storm. 



9. On the 6th, the storms were all breaking up and moderating. 



10. That where the circumferences of the various circles met, and 

 particularly on the 5th, there was a continual " veering about of the 

 wind," though blowing a full storm. 



11. That at some places, as Gya and Amooah in Tirhoot, the storm 

 though not felt as one at the surface, was distinctly seen overhead, 

 driving the clouds about in all directions. 



12. That at the line of stations along the base of the Northern 

 hills, the storms felt were not rotatory ones, but probably composed of 

 the Northern quadrants of these circular storms to the South, and the 

 great Easterly current formed by the deflection of the S. W. mon- 

 soon from the Arracan, Cachar, and Bootan hills, as shewn in my 

 first Memoir for the storm of June, 1839. 



13. That the greatest intensity of the various storms was that at 

 Calcutta, for they are no where spoken of, nor are any facts recorded, 

 which would lead us to suppose, that they were at any place the furious 

 hurricane, which during some hours the storm undoubtedly was at 

 Calcutta. 



Conclusion. 



I will not omit here one remark, to which I request the attention, as 

 well of those who have kindly assisted our researches as those who 

 might, but have not done so ; and this is, that all will consider how 

 much has here been demonstrated, and inferred from evidence literally 

 collected piecemeal, and of which each separate part would have been 

 comparatively valueless, if not aiding to form the whole. There can
