 of the nasturtium during a sultry tempestuous 

 night. Another instance was recorded in 1843, 

 when Mr. Dowden mentioned a luminous appearance 

 in the double variety of the common marigold. This 

 circumstance was noticed on the 4th August, 1842, 

 at 8 o'clock p.m., after a week of very dry weather. 

 Four persons observed the phenomenon. By shading 

 off the declining day-light, a gold-coloured lambent 

 light appeared to play from petal to petal of the 

 flowers, so as to make a more or less interrupted 

 corona around the disc. It seemed as if this emana-

 and another instance was recorded: "We witnessed
