134 ON ATMOSPHERIC AND BAROMETRIC 



The highest temperature 84°. 1 is found at two 

 o'clock, after which time it declines a little till 

 four when it is at 83°. 9 ; — and if high temperature, 

 as measured by the thermometer, really produced 

 the sea breeze, it should have increased in strength 

 until two, when as the temperature declined, the 

 breeze should also decline. But the sea breeze 

 is found the strongest from two to four o'clock. 

 The sea breeze, therefore, is of inferior strength 

 up to two o'clock, when it ought to be the strong- 

 est, and it is the strongest when it should, accord- 

 ing to the temperature theory have been for two 

 hours becoming weaker. 



At four, although the atmosphere, as shown by 

 the thermometer had become colder than it was 

 at two o'clock by .2, yet it was then in its lightest 

 state, as measured by the barometer, showing that 

 the temperature and weight of the atmosphere 

 were not in harmony with each other. After 

 four the barometer begins to rise, and the sea 

 breeze to weaken, and these alterations proceed 

 until near ten at night, when they cease. 



At this time the air over the land as measured 

 by the barometer, is found to be heavier than that 

 over the sea, and the aerial current turns and
