12 REPORT ON THE RELATION BETWEEN 



In a few instances I have given the contemporaneous barometric curves 

 at two or three stations far apart, as London, Versailles, and Goersdorf on the 

 Lower Rhine ; London and Rouen, &e. 



lYS^ The diagram (Plate H.) shows the barometric curve at London, 



from observations published in the ' Gentleman's Magazine ' of the time, in 

 December. On the 6th the mercury fell to 28*25 inciies. A general storm 

 of unusual violence accompanied this great depression. 



Onlj'^ two explosions are recorded in this year, of which one (at Wallsend, 

 Northumberland) occurs before the rear of the cyclone has passed over, on 

 the 12th of December. 



1818, April 9. — By a great explosion at Warnes, near Mons, between thirty 

 and forty persons lost their lives on this day. 



The curve (Plate V.) shows that a regular cyclone passed over Britain from 

 the 5th to the 12th. Howard, in his ' Climate of London,' records a gale 

 from the S. on the 8th, and states the 9th, 10th, and 11th to have been 

 windy. No explosions are recorded in Britain during 1818. 



1821. October. — From the 30th of September to the 9th of October, 1821, a 

 regular West Indian hurricane, beginning at N.N.E.and ending at S.S.W. (and 

 therefore progressing towards Florida, Newfoundland and Great Britain), 

 blew between Jamaica and Cuba (Howard, vol. iii. p. 63). 



The great barometric depression at London (Plate V.), from observations 

 by Howard, between the 16th and 26th, indicates the passage of this cyclone 

 over England. The barometer was equally low at Newcastle-upon-Tyne. 



There ave Jive explosions recorded in 1821, tivo on the same day, July 9, 

 at Rainton Colliery and Coxlodge Colliery, in the North of England, coin- 

 cident with a rise of temperature, and the remaining three just as the central 

 area of this cyclone was passing over Britain. These also occur in the North 

 of England ; thus — on October 19, at Nesham's Pit, Newbottle (six killed) ; 

 Oct. 23, Russel's Pit, Wallsend (fifty-two killed) ; Oct. 23, Felling Colliery 

 (six killed). 



1823, November. — A great storm passed over Britain at the end of October. 

 On the 30th and 31st alone, 140 vessels were lost on- the N.E. coast. At 

 Penzance, the wind suddenly shifted from E.S.E. to N.E. and N.N.E., and 

 instantly blew a hurricane. This shows the progressive motion of a revolving 

 storm to the eastward. In Plate II. are given the barometric curves for 

 London and Boston during the transit of this cyclone. 



On November 3, before the storm had ceased, an explosion at Plain Pit, 

 Rainton, Durham, destroyed fifty-nine men. This, and an explosion at 

 Ouston Colliery on the 21st of February, are all that are recorded during 1823. 



1828, Nov. 20. — At W^ashington Colliery fourteen persons killed by an ex- 

 plosion. Howard's curve (Plate II.) shows that a great barometric depres- 

 sion immediately preceded this catastrophe. 



1844, January. — A very heavy storm of thunder, lightning, hail and rain, 

 passed over the counties of Lancashire and Cheshire on the 1st of January. 

 The barometric curve at Makerstoun shows that the storm was general and 

 lasted for several days. The contemporaneous explosions are on December 31, 

 1843, Hulton Pit; on January 8, 1844, Dynas Pit, Glamorganshire (ten 

 killed); Jan. 11, Whitehaven, Cumberland (sixteen killed); Jan. 18, Kil- 

 lingworth Colliery, Northumberland (five killed). 



1844. October. — The great Cuba hurricane, investigated by Redfield, oc- 

 curred on the 3rd and 4th of October at Cuba and Jamaica, and passing over 

 Florida, the Bahamas, &c. in a N.E. track, reached Newfoundland on the 

 8th (see Col. Reid's work). At Havannah, seventy-two ships were wrecked 

 or sunk, houses were unroofed, crops destroyed, &c., the estimated loss there
