13 Four years. A transatlantic climate. 



14 Buch, two years. Mean temperature of the winter scarcely 

 29-5°. West coast. 



15 Alps of Bavaria. Six years' observations, calculated by 

 M. Wahlenberg. Many fruit trees. Convent of Tegernsee, in 

 Bavaria, height of 2,292 feet; mean temperature of 1785, 42 , 2°; 

 Peyssenberg, 41°. 



16 Bugge. Three months below 32°. Under the equator, 

 mean temperature of 44 - 6°, at an elevation of 18,000 feet. 



17 Dalton. West of England. Climate of islands ; springs 

 47-2°. Keswick, lat. 54° 33', long. 5° 23' W. ; mean tempera- 

 ture, 48° ; springs, 48-6°. 



18 Kirwan. Scarcely two years' observations. Southern 

 latitude. 



19 Strnadt. Fifteen years. Climate of the continent of 

 Europe. 



40 Maier. 



21 Six years' observations of M. Escher, calculated by Wah- 

 lenberg. The town is situated in a hollow, to which the warm 

 winds cannot penetrate, that render the winters more temperate 

 in the other parts of Switzerland. 



22 The calculation has been made from six years of excellent 

 observations, by Professor Playfair ; during this time the ther- 

 mometer was never seen above 75-8°. Vegetation continues 

 from March 20 to Oct. 20 ; mean temperature of these seven 

 months is from 55-8° to 50*9°, according as the years are more 

 or less fruitful ; wheat does not ripen if the mean temperature 

 descends to 47'6°. 



25 Guittard. Only three years. Mean temperature a little too 

 high. Eastern part of Europe. A continental climate. 



84 Four years of observations, by M. de Salis Sewis, calcu- 

 lated by M. Wahlenberg. Mountains of the Grisons. 



45 Kirwan. Irish Trans, viii. 203, and 269. Specimen of the 

 climate of the islands. Coldest days, 23°; interior of the 

 ground, 49-2°. Hamilton. 



26 The climate of Berne is a continental climate, in comparison 

 with that of Geneva ; there is no lake near it. 



27 Seven years of observations. Saussure. Mean temperature, 

 50-8°. Voy. § 1418. I find the mean temperature from 1796

 Brit. 1817. iv. 109. 



28 Six years.

 46-4° to 47-3°; according to Beguelin, 48'8°; springs, 49-2 6 . 

 Ratisbon, lat. 49° ; height, 1,104 feet; mean temperature, 51-2°. 

 Munich, lat. 48° 8'; height, 1,608 feet; mean temperature, 

 50-8°. 



50 Ramond. Seven years of excellent observations. The 

 mean of the months, at noon, well ascertained ; winter, 40° ;
