and Remarkable Atmospherical Plienomena. 387 



Another series of remarkable states of the atmosphere, with simi- 

 lar intervals, will be found in connection with the earthquakes in 

 Huntingdon, on the 26th of March last : — 



1845. 



Jan. 28. Barometer at Chiswick 2«"y32 ; lower than for 79 days before 

 and ever since. 



Feb. 26. Thermometer at Chiswick 52' ; higher than for 31 days before 

 and 25 daj's after. 



March 26. Shock of earthquake this evening at Huntingdon,* &c. 



April 25. Barometer at Penzance this evening lower than for 15 days 

 before and 40 days after. 



May 25. About 2 o'clock a.m., at Penzance, a severe thunder-storm, 

 with unusually heavy rain. In the afternoon " a terrible 

 shower of hail desolated several communes of the provinces 

 of Brabant, — the hailstones were of enormous size." 

 Here I may add, that, on the 19th August, which is about 

 three lunations after this dreadful hail-storm, a most awful 

 whirlwind visited the neighbourhood of Rouen. "Houses, 

 trees, and crops were swept away, and so mingled, that of 

 some buildings it was impossible to trace the site. Three 

 large factories were hurled down," and a great many per- 

 sons perished. 

 The 20th of August was predicted by M. Arago to be the 

 commencement of a long period of fine weather^ which has 

 since occurred. 



So, also, before and after the great earthquake in Mexico, on the 

 "Tth of April last, there were other earthquakes and remarkable at- 

 mospherical phenomena, at intervals of about single lunations, and 

 near the times of new moon : — 



1845. 



March 9: Eartliquakes throughout Mexico, and at Campsie near Glas- 

 gow.! Singular appearance of the sun observed at Cam- 

 bridge,! within two hours after the shock near Glasgow. 

 The driest day of the month in Cornwall. M. Arago pre- 

 dicted that on the 8th of March (new moon) the Seine 

 would be frozen over, which has proved correct. 



April 7. Another earthquake throughout Mexico, severer than any ex- 

 perienced there before for above a century. Shock also felt 

 at sea near the equator, in long. W. 27' 17' . The air in 

 Cornwall drier, by many degrees, than on any other day 

 of the year up to August. 



May 8. Barometer at Penzance lower than for 11 days before and 26 

 days after. At Chiswick it was 29-407 ; lower than for 23 

 days before and 25 days after. 



June 5. A violent storm at Penzance from SW. — Barometer there 

 this evening lower than for 56 days before and 22 days 

 after. 



July 5. Barometer at Penzance higher than for 11 days before and 9 

 days after,— the maximum at Chiswick being 30-196; higher 

 than for 24 days before and above 26 days after. Dread-
