238 Prof. Dove's Outlines of a general Theory of the Winds. 



in Holland, according to the observations of Horsley* and 

 Van Swinden, while the west winds commonly cause it to rise ? 

 No hypothesis with which I am acquainted gives a satisfactory 

 reason." 



11. Denmark. During 1100 changes of the direction of 

 the wind observed in Apenrade by Dr. Neuberf, 559 were 

 in the direction of S., W., N., E., S.; 457 in the contrary. 



12. Sweden. " In order to examine how far these changes 

 (namely those motions of the barometer calculated by me in 

 Paris, from the law of rotation for hydrometeors,) take place 

 in other countries during rain. I have," says Dr. Kamtz %, 

 " brought together in a similar manner the calculations of Ni- 

 cander in Stockholm. Of three observations out of nineteen, 

 made between 2 and 9 o'clock, I have taken as a basis for the 

 comparison the wind which blew about 2 o'clock. The fol- 

 lowing table contains the magnitudes found, in Parisian lines : 



"On the day before and during the rain, the barometer sinks 

 with easterly, rises with westerly winds, just as Dove has de- 

 duced from observations in Paris." 



13. North America. In the State of Missouri, the wind in 

 constant repetition traverses within from ten to twenty days 

 every quarter of the horizon, and always in the following order, 

 going from E. through S. to W., and through N. toward E. 

 Duden^, who makes this remark, adds that he never had ob- 

 served a completely opposite course.

* In regard to Horsley, Saussure is in error : he had only calculated the 

 averages, but not examined the rise and fall.
