The curves of April 28 show clearly that the influence 

 of the moment of inertness of the aneaiometer-wings is 

 verv small. By the installation of the anemometers in the 

 ends of a horizontal beam, the wind w^orked in the same 

 manner on both instruments. As we remember the 

 Anemometer I had a diameter af 18.3 cm and a moment 



of inertness 1083.61. 

 Anemometer II had a diameter of 13.4 cm and a moment 



of inertness 312.6 6. 

 The lower cm^ve corresponds to the anemom. I. 

 » upper » > II. 



The registered number of points are given here as an 

 example. The resulting velocity can be casily calulated in 

 using the tables page 8.
