Obituary notice of Melloni.—The philosopher Melloni, whose death 
we announced in November, 1854, was born near the commencement 
of the century at nee where he began his studies. His sagacious 
and observing mind was soon apparent to his parents and teachers. 
The phenomena of the dian of heat even thus early interested him 
and he was not slow to suspect the analogy between the radiation of 
heat and of light. More fortunate than Laurent and other poene 
youths, the young Macedoine Melloni had at least the satisfaction of 
seeing himself understood by those who had charge of his education. 
They 6 ag his studious habits instead of endeavoring to divert 
him, and when in 1824 the Chair of Physics at Parma became vacant, 
Melloni was enaiaias to it mys he had not then published any of 
his researches. 
Completely destitute of instruments, the young professor devoted his 
first efforts to contriving them, No bili had just then constructed his 
thermoscope. Melloni soon brought it to perfection, and Nobili was so 
pleased with. the result that he proffere red him his friendship. A note
