RESULTS OP METEOROLOGICAL OBSERVATIONS 



est month the monthly means have a range of 23|°, which is reduced in the third 

 month of summer to 13°. In connection with this it appears also that the repre- 

 sentation of the monthly means by a circular function is generally better for the 

 summer than for the winter seasons. 



Extreme Temperatures observed. 



Between the limits already stated, comprising about ten years, we have a daily 

 record of the extreme temperatures by means of a maximum and minimum ther- 

 mometer; the following tables exhibit the observed extreme lowest temperature 

 and the observed extreme highest temperature in each month.

The monthly numbers in the two preceding tables appeared so regular that mean 

 values could be set down ; these will advantageously compare with similar quanti- 

 ties at other stations. Average monthly range 56°. 



The total range of temperature experienced at Brunswick is very considerable^ — 

 not less than 132° Fahr. The lowest temperature recorded is — 30", and the 

 highest 102°. 



' At the three Arctic stations, Port Foulke, Van Rensselaer Harbor, and Port Kennedy, the 

 extreme range was respectively 108°, 117°, and 105° Fahr._
