PREFACE TO THE SECOND AND THIRD EDITIONS. XV 



altogether restoring to the latter with certainty its ancient 

 pre-eminence among the snowy summits of the New World. 

 In the Himalaya the recently executed trigonometrical 

 measurement of the Kinchinjinga (28178 English feet) places 

 it next in altitude to the Dhawalagiri, a new and more exact 

 trigonometrical measurement of which has also been recently 

 made. 



For the sake of uniformity with the two previous editions 

 of the " Ansichten der Natur," I have given the degrees of 

 temperature in the present work (unless where expressly 

 stated otherwise) in degrees of Reaumur's scale. The linear 

 measures are the old French, in which the toise equals six 

 Parisian feet. The miles are geographical, fifteen to a degree 

 of the equator. The longitudes are reckoned from the 

 Observatory at Paris as a first meridian.
