it is a stock subject of conversation. St. Moritz Dorf 

 is the highest part of the valley of the Eugadine, and, 

 therefore, when a fohn wind is blowing in the neighbour- 

 hood it frequently deposits its moisture in St. Moritz, or if 

 not snowing, or raining, is a damp wind. In Davos, on the 

 other hand, the fohn wind has to descend from a greater 

 height, and has passed over a range of mountains, and is 

 in consequence of its descent a warm and dry wind, at any 

 rate for part of its duration. The winter of 1882-1(S83 gave 

 some very interesting examples, showing that the theory 

 given above was sufScient to explain what was taking 

 place. On the days with strongest fohn, viz. : November 7th 

 St. Moritz had at 1 p.m. +3'2 Cent., while Davos had 

 + 13 Cent.; November 8th St. Moritz had +21 Cent., Davos 

 + 7 Cent.; December 4th St, Moritz was at 1 p.m. - 5 Cent., 

 Davos was +4 Cent.; January 30th St. Moritz was —08 

 Cent., Davos was +5 Cent. 



It will be seen that whereas St. Moritz has no depressing 

 fohn, its absence at such times has to be paid for by a 

 colder and damper air together with a strong wind (which 

 is more trying as it is cold). My own opinion is that for 

 some individuals the disadvantages of the fohn outweigh 

 the disadvantages of the colder and moister air, while 

 others can better bear the bracing and cold air than the 

 depressing one, and as such places as Arosa, Pontresina, 

 the neighbourhood of Schuls, &;c., have been thought of as 

 winter health resorts, it becomes important first to study 

 how the wind affects each of them ; for, as I have elsewhere 

 said, I believe that the difference of some of these places, 

 quite near together, is as great as between Brighton and 

 Torquay. 



In order, therefore, to study the influence of the wind on 

 people, we ought first of all to know the force at about the 

 height of a person, and then we ought to know the direction 

 (and if possible the force) of the main upper current, for of
