During the year 1838, as during 1837, the Temperature of the 

 month of October approaches nearest to that of the year, the Mini- 

 mum differing only 0.5" or half a degree, the mean x2.06° and the 

 Maximum, 1.5°. The mean of the two Annual extremes being 69° 

 exhibits a difference from the annual Mean of only +0.085, so that 

 when the Maxima and Minima for the year are given, the mean 

 Annual Temperature may be ascertained within a very limited error. 

 The warmest day of the year was the 17th of June, the coldest the 

 25th of December, the extreme Annual range of the instrument being 

 51°, the Mean range 34.91°. The extreme range at Surrowli is 15 

 degrees greater than at Kulsea, a difference due no doubt to the 

 Thermometer in the latter case being within, in the former without, 

 doors.
