[Vol. XX. No. 501 



QUERY. 



Can any reader of Science cite 

 a case of lightning stroke in 

 which the dissipation of a small 

 conductor (one-sixteenth of an 

 inch in diameter, say,) has failed 

 to protect between two horizon- 

 tal planes passing through its 

 upper and lower ends respective- 

 ly? Plenty of cases have been 

 found which show that when the 

 conductor is dissipated the build- 

 ing is not injured to the extent 

 explained (for many of these see 

 volumes of Philosophical Trans- 

 actions at the time when Lght 

 ning was attracting the attention 

 of the Royal Society), but not 

 an exception is yet known, al- 

 though this query has been pub 

 lished far and wide among elec- 

 tricians.
