XXI. On the greater calorific Effect of the Sun's direct Rays 

 in high than in low Latitudes. By James Dalmahoy, Esq., 

 Surgeon, Hon. R.l.C.S.% 



T is well known that experiments have been adduced to 

 prove that, at equal altitudes of the sun, the heating power 

 of its direct rays is greater in high than in low latitudes. 



The following is an attempt to reconcile this result with 

 the received theory of radiant heat. 



MM. Dulong and Petit have discovered that if the initial
