The quantity AE, or 



RT — rH 

 R — r 



, is fuppofed here to 



be fubtracted ; if R T be lefs than r H, it will change its fign, 

 and mult be taken on the other fide of the centre A. 



10. The refults of thefe deductions may be ealily reprefent- 

 ed numerically, and reduced into tables, for any particular 

 values that may be affigned to the conflant quantities. Thus, 

 if the radius of the globe, or R zz 100, that of the ignited nu- 

 cleus or r zz 1 j the temperature of the nucleus, or H r= 1000, 

 and T the temperature at the furface = 60, the formula be- 



comes h — 50.505 -j-
