high as that of Amsterdam, though it be a degree and a half 

 more to the south. 



In Devonshire, the town of Salcombe enjoys a climate which 

 has procured for it the appellation of the Montpellier of the 

 I^orth. 



-f Marseilles is more than a degree to the south of Genoa ; the 

 mean temperature of this latter, then, ought to be a degree of 

 Fahrenheit's scale less than that of Marseilles, — on the contrary, 

 however, it is two degrees higher. 



We ought not to be surprised that Marseilles, a maritime town, 

 should have a climate warmer than that of Avignon, situated 

 somewhat more to the north, and in the interior of the country^ 

 — that the winters there should be sensibly more cold, and the 

 summers sensibly hotter ; but let us here ask, what is the cause 

 that the mean temperature of Marseilles is less than that of 

 Avignon ? 



' Rome and Perpignan have exactly the same mean tempera- 

 ture, although the former place is a degree more southerly. If 

 the cause of this were demanded, allusion would probably be 

 made to the Apennines ; but then, Perpignan is at the foot of 

 the Pyrenees. 



But we shall not push such- statements further. Plausible 

 explanations might be offered of many of the anomalies, found- 

 ed on the particular configuration of the countries in which these 

 towns are situated, &c. &c. But this is not the question. What 

 we have stated, and we still maintain, is, that the alleged causes 

 of these anomalies are not remarkable ; that an attentive ex- 

 amination of the localities would scarcely enable us to predi- 

 cate what would be their effect, or in what way they would ope- 

 rate. 



And this finishes the task we had undertaken. We shall 

 conclude this long article, by briefly examining whether the 

 mean temperature of Paris has, in our days, undergone any 

 change. 



Nothing, at first sight, can appear more simple than this ques- 

 tion. The temperature des souterrains, which are not at all deep, 

 and into which the external air has not free access, not only does 

 not vary, but, moreover, it is equal to the mean temperature of 

 the external atmosphere at the surface. This is the character
