On Fulgurites from Griqualand West
Published online by Cambridge University Press: 14 March 2018
Extract
Through the kindness of Professor D. Hahn of the South African College, Cape Town, I received, some time since, a series of specimens of fulgurites which were collected in the vicinity of Griquastad.
In this locality Professor Hahn informs me that there is a particular sand hill which is noted among the farmers living in the neighbourhood for the frequency with which it is struck by lightning during thunderstorms.
