" Forsitan et rosea Sol alte lampade lucens, 

 Possideat multum caecis fervoribus ignem 

 Cireum se, qui sit fulgore notatus, 

 iEstifer ut tantum radiorum exaugeat ictum." 



Lucretius, v. 610. 



" Perhaps too the sun as he shines aloft with rosy lamp has round 

 about him much fire with heats that are not visible, and thus the fire may 

 be marked by no radiance, so that fraught with heat it increases to such 

 a degree the stroke of the rays." — Monro's Translation. 



My attention was drawn to this remarkable passage by the late ex- 

 cellent and accomplished Sir Edmund Head, Bart.
