by our author for their simplicity and probity of character. 

 They revolted from the Sultan under a chieftain called Tzerni 

 George about the beginning of the century, and though re- 

 duced to submission in 1812, when the Porte had concluded a 

 treaty of peace with Russia, and had its troops at liberty, yet 

 afterwards they were driven to take up arms by the oppres- 

 sion they underwent, and at length obtained of the Sultan a 

 kind of half compromise, which left them at liberty to govern 

 themselves under the superintendence of a native Servian 

 prince, Milosch, paying an annual tribute only to the Sove- 

 reign. Prince Milosch is represented as a man of great natu-

 read or write. With many of the vices of the barbarian, he 

 seemed in the main well fitted to govern such a people, affect-

 conducting the government in an Eastern fashion, exempt 

 from many of the abuses that had crept into the Turkish ad- 

 ministration. Dr Boue contrasts the state of things in Servia 

 and in Greece, and gives the preference to the former. 



He concludes with a table of the heights above the sea of 

 no less than 350 places, measured by himself barometrically 

 during his travels in Turkey. 



Appendix to Br Richardson's Observations on Solar Radiation. 



Professor Forbes having referred to Leslie's Photometer 

 in the remarks which he has had the kindness to make on 

 my observations, I have, with the view of rendering the 

 paper more complete, added two tables containing abstracts 

 of a register of that instrument kept at the same time with 

 that of the radiation thermometers. In the spring months the 

 action of the sun on the photometer was so powerful as to 

 drive the coloured liquid beyond the limits of the scale at- 

 tached to the instrument, and in twelve different instances, in 

 March 1826, entirely into the clear bulb. To remedy the 

 shortness of the scale, I divided the two limbs of the photo- 

 meter, including the bend at the bottom, into 35°, each de-
