170 'Die Influence of the Soil 



The annual barometrical variations at Kitzbuhel are compris- 

 ed between 693,33 and 715,08. 



The thermometrical observations were continued for three 

 years, — from 1831 to 1834: and were made three times every 

 day, — at 7, 12, and 5 o'clock. The mean temperature of each 

 month was, — January, — 2,69 ; February, — 0,21 ; March, 

 + 2,21; April, 4 6,80; May, 411,49; June, 413,28; July, 

 414,99; August, 414,77; September, 411,25; October, 

 46,98; November, 41,72; December, — 1,05. The mean 

 temperature of the year is 6,21 ; whilst at Inspruck it is 7,21. 

 This result perfectly agrees with the law established by Schiib- 

 ler, according to which this mean temperature diminishes a 

 degree of Reaumur for every 533 feet up to the height of 3000 

 feet. The maximum of temperature at Kitzbuhel was on the 

 11th of July, 1832, when the thermometer stood at 22,0; and 

 the minimum on the 3rd, 19th, and 22nd of January, in the 

 same year, when it stood at — 12,0 ; which gives an interval 

 of 34°. 



The climate of Kitzbuhel is humid, for we find 125 rainy 

 days. In winter the country is covered with snow, from four 

 to six feet deep ; which does not entirely disappear until the 

 month of May. Storms are frequent, and the winds very vio- 

 lent ; that from the south sometimes overthrowing houses and 

 tearing up trees. Ten tables are appended to the meteorolo- 

 gical portion of the work, which we have been thus rapidly 

 analysing ; they contain a multitude of observations, placed 

 in . comparison with those made at Inspruck, Trieste, and 

 Gries. 



Taking into consideration all the circumstances we have 

 just mentioned, we shall be led to conclude that the Flora of 

 Kitzbuhel must have an alpine character. It accordingly be- 

 longs to that great system which extends from the Pyrenees 

 to the range of the Caucasus. Along this extensive line, ve- 

 getation exhibits many common characters, but it also pre- 

 sents some remarkable differences. Thus, the Flora of the 

 Pyrenees differs less from that of the Alps, than does this lat- 

 ter from the vegetation of the Caucasus. The Tyrol lying 

 between the two, it follows that a host of western plants reach 

 its limits, while those of the eastern extremity are quite fo- 

 reign to us. Thus the Petrocallis pyrenaica, Horminum py- 

 renaicum, and Potentilla nivea, are common to it with Swit- 

 zerland, Dauphigny, Provence, and the Pyrenees. Others, 

 which grow only here and there in privileged localities, ex- 

 tend very far towards the east, yet without penetrating into 

 this country; such are the Geranium pyrenaicum, Valeriana 

 saliunca, Papaver pyrenaicum, and Ornithogalum pyrenai-
