The foregoing results give a mean temperature of 67 0, 46 : 

 as however the observations at 4 and 8 p.m. give higher re- 

 sults than would have been afforded if the observations had 

 been made at 3 and 9 p.m. instead, and as we are without 

 observations at 3 a.m., I consider the foregoing temperature 

 about 2°*3 above the true mean, which in this case will be 

 about 65°-14. 



Circumstances have prevented my making many compari- 

 sons between the indications of the thermometer in the shade 

 and when exposed to the direct action of the sun's rays. In 

 the following instances, however, the instrument was suspended 

 at about three feet above a surface of newly-turned garden- 

 mould, of a deep red colour.

My garden is a level spot of about one-third of an acre in 

 area, and contains several orange and coffee trees, besides 

 other shrubs; none of them, however, are very large; and 

 the rain-gauge is placed on the ground at a distance from 

 them all, in the centre of the garden.
