278 Mr. J. Hogg and Sig. Tenore on the comparative Influence 



changes of the atmosphere are so instantaneous that one may 

 in the same day be overcome with heal, and so cold as to re- 

 quire a fire. The winter is mild and rather damp; but snow 

 very rarely falls. In Naples the thermometer in winter has 

 been known to descend so low as the fourth degree below zero 

 of Reaumur, or nine degrees below the freezing point of Fah- 

 renheit. 



The sea-breezes and the west winds make the great heats 

 of the summer to be endured in the capital. Then most vio- 

 lent thunder storms are very frequent, being attracted by the 

 lofty range of the Apennines, which occupy the larger por- 

 tion of the kingdom ; for in that season the thermometer 

 stands almost always between 20° and 22° Reaum. (77° and 

 81^ Fahr.), and for a few days it will even ascend to 23° and 

 25° Reaum. (84° and 8S° nearly Fahr.). 



Indeed, the general stale of the weather during the twelve 

 months successively will be more accurately comprehended 

 from the following Table* of the mean meteorological obser- 

 vations taken at the Royal Observatory of Naples for five 

 years, viz. from 1821 to 1S25 inclusive. 



* Compare this with the Journals kept by the Royal Society in London, 

 and published in the Philosophical Transactions for those years, and with 

 the Meteorological Tables given in the Annals of Philosophy of the same 

 years. Also with the tables of the weather kept near High Wycombe, 

 Bucks, at p. 351, vol. v. of Loudon's Magazine of Natural History, wherein 

 the years 1823, 1824 and 1825 are stated. I have not thought it neces- 

 sary to reduce the French proportions used in Tenure's Tabic to our En- 

 glish scales.
