Meteorological Journal for the City of Cork. By T. Holt, Esq. 



(To Dr. Thomson.) 



SIR, Cork, Jan.3l, 1818. 



I enclose you a meteorological scale (PI. LXXXIX) and ac- 

 companying Journal for the last three months of 1817. Should 

 you deem it worthy a place in your Annals of Philosophy, 1 shall 

 continue my observations, andean transmit thein quarterly, or half 

 yearly. Of the barometer I have enclosed two lines of variation, to 

 explain which it will be necessary for me to observe, that I live 

 on an elevation of about 960 feet above the level of the sea ; but 

 as my daily occupation is in the city of Cork, I have an 

 opportunity of regularly observing the variations of both baro- 

 meter and thermometer every day, and within '20 minutes' 

 difference. The time of observation was on the hill about an 

 hour, and in the town about 40 minutes before sun-rise ; and if 

 any material variation occurred in the course of the day, it was 

 noted. The difference in the heights of the thermometer seldom 

 exceeded one degree. I am, Sir, with due respect, 



Your very obedient servant, 



Thomas Holt.
