Article II. 



Results of various Meteorological Registers for the Year 1825. 



1 . For Helston, in Cornwall. By M. P. Moyle, Esq. 



(To the Editors of the Annals of Philosophy .) 



GENTLEMEN, Hdston, Jan. 2, 1826. 



In transmitting you my Meteorological Journal for the past 

 year, I beg to remark that it differs only from my former method 

 of observation in having a black bulb thermometer placed in the 

 direct rays of the sun ; its bulb has a slight coat of black paint, 

 into which is stuck a quantity of finely chopped black wool, and 

 it is mounted on a box-wood scale, a foot above the slated roof of 

 a house. It may be useful in ascertaining the solar radiation of 

 this part of the country. 



I am, Gentlemen, your obedient servant, 



M. P. Moyle.
