Some Statistics of Thunder mid Liglitnincj at Kimberley. 115 
winter thunderstorms conform in some respects to Ley's first class ; those of 
the other seasons more to that of his second class. Both divisions of the 
year, however, have storms which have points of resemblance to his third 
class. But these are details which I hope to discuss at some more favour- 
able time. 
A phenomenon of interest is the " smell " of a thunderstorm. This I 
have only observed once in Kimberley, and that strongly. European meteoro- 
logical literature of the seventeenth and eighteenth centuries has many allu- 
sions to the "sulphureous smell" of lightning, especially when anything 
was struck ; and the observation goes back even to the time of Homer 
(Odyssey, XII). Before the time of Franklin theorists had, because of this 
odour, attributed lightning to the " breath of pyrites."
