In twenty-four hours in January, fell 5.24 inches. A few observations taken on board the Beagle during the five days it lay at Santa Cruz seemed to give a mean heat of about 76 degrees; but it must be remembered that these observations were made in a vessel lying only about a quarter of a mile from the shore and exposed to the constant rays of the sun during six days of a season considered by the inhabitants to be a very warm one. I do not therefore think that the observations of Dr. Savignon and Mr. Richardson, taken under such very different circumstances at Laguna, which Von Buch estimates at 264 toises above the sea, could be far from the truth. The annual mean temperature of Santa Cruz according to Von Buch is 71 degrees 8' Fahrenheit, or 21 degrees 8' of the centigrade scale. OCCASIONAL VIOLENT STORMS. From Mr. Cochrane, a very intelligent English merchant whom I met there, I obtained much information on various points, and he brought to my notice the violent storms of wind and rain which occur on the island occasionally during the rainy season, and cause great destruction and damage. DAMAGE BY STORM OF 1826. One had passed over in the month of March of the year I was there (1837) and I was fortunate enough to obtain an official account of the damage occasioned by another in November 1826, which is here annexed. A similar one was experienced, as will be seen by the table, in January 1812, when 5.24 inches of rain fell in twenty-four hours. En la noche del 7 al 8 de Novembre 1826, se experimento un temporal de Viento y Agua, que causo on todas les Yslas muchos estragos. En 8 pueblos de la de Tenerife, se sufrion las des-gracias que manifiesta el siguente Estado.
