Mr. Rico has laid before the Royal 
Society a propofal for anew Compenta= 
tion Pendulum. In the courfe of various 
experiments he has difcovered that of all 
the modes of compenfation, that of tri- 
angles is the beft. He has accordingly 
conftructed one of triangles, two fides of 
which are fteel, and the bafe brafs or 
zinc, which expands twice as much as 
fteel; and hence the expanfion of the 
fides is properly countera¢ted by the ex- 
panfion ef the bafe. In this way Mr. R. 
affirms that pendulums may be coniiruct-. 
ed of any feries of triangles, that would 
continue the fame length throughout all 
climates and feafons.
