556 NEW METHOD OF DETERMINING THE WINDS VELOCITY. 



removed from or about the premises, and disinfectants freely used. If this 

 cannot be done by the persons themselves, immediate notice should be giv- 

 en to the Inspector of Nuisances. 



5. The existence ot nuisances of a»y kind and wheresoever situated 

 should be at once reported to the Inspector of Nuisances. 



VI. During the prevalence of epidemic, infectious or contagious dis- 

 eases, it becomes specially important that the general laws regarding the 

 preservation of health should be rigidly attended to. 



2. Implicit trust should not be placed in so called "disinfectants." 

 They are very useful when judiciously employed, but are b}^ no means cer- 

 tain "preventives of disease."' 



3. Pure air, pure water, warm clothing and good food should always 

 be obtained if possible. B}- their constant use less chance is aftbrded for 

 an invasion of disease. 



4. Temperance both in eating and drinking is essential for the main- 

 tenance of health and the prevention of disease. 



5. Overcrowding in houses, workshops or schools should be strictly pro- 

 hibited. 



6. All houses, cottages, schools and public rooms should be kept clean 

 and well ventilated; and frequent use of lime washing on the walls and 

 ceilings should be made. — Druggists'' Circular. 



METEOROLOGY. 



A NEW METHOD OF DETERMINING THE WIND'S VELOCITY. 



BY JOHN H. LONG, OLATHE, KANSAS. 



A paper read before the Kans?s Academy of Science, October 12, 1877. 



It having been repeated stated by certain observers in Kansas that the 

 anemometer of the State University registered a higher than probable vel- 

 ocity, I was induced at the suggestion of two gentlemen connected with the 

 institution, to test the correctness of the instrument. The apparatus used 

 by me was very simple, consisting essentially of a hollow copper sphere sus- 

 pended in front of a graduated horizontal scale. But as a more detailed 

 description may be necessary to the understanding of what follows, I will 

 give it here. Imagine first a perpendicular shaft of iron, eighteen feet long> 

 whose bottom fits into a socket and to Avhose top is attached a swivel. To 

 this swivel are attached several wires whose other extremities are secured 

 so as to give complete steadiness to the shaft. Other braces are attached 

 for the same purpose, and the swivel on top permits it to turn to suit the
