208 DOVE ON THE LAW OF STORMS. 
storms, which did not extend beyond the tropics, are recti- t 
linear; that of the 23rd of June, 1831, passes from Trinidad by 
Tobago and Granada, through the middle of Yucatan to the — 
neighbourhood of Vera Cruz; that of the 12th of August, 1835, 
passing from Antigua by Nevis, St. Thomas, St. Croix, Porto 
Rico, Hayti, Matanzas and Cuba, and thence to Texas.

Jago de Cuba on the 13th, Matanzas on the 14th, the Tortugas 
on the 15th, the Gulf of Mexico on the 16th, and finally, Mo- 
bile, Pensacola and New Orleans on the 17th, so that it had 
passed over a space of 2000 nautical miles in about 150 hours, 
or at the rate of 13} miles in one hour. Its direction before 
reaching the tropic was N. 64° W. 
The storm which began on the 17th of August, 1827, in the 
neighbourhood of Martinique, reached St. Martin and St. Tho-

tucket on the 27th, Sable Island and Porpoise Bank on the 28th, 
having passed over 3000 nautical miles in eleven days. Within — 
the tropics the direction of its path was N. 61° W.; in the lati- 
tude of 40° it was N. 58° E. 
The storm which began in the neighbourhood of Guadaloupe 
on the 3rd of September, 1804, reached the Virgin Islands and
