New Method of Protecting Properlv 

 from Lightning. 



Tie LigMning Dispeller. 



Price, $20 to $30.— According to size. 



The Patent Lightning Dispeller is a conduc- 

 tor specially designed to dissipate the energy 

 o£ a lightning discharge, — to prevent its 

 doing harm, — placing something in its path 

 upon which its capacity for causing damage 

 may be expended. 



No recorded case of lightning stroke has 

 yet been cited against the principle of the 

 Dispeller. So far as known, the dissipation 

 of a conductor has invariably protected under 

 the conditions employed.

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 ac the time when light- 

 ning was attracting the attention 

 of the Royal Society"), but not 

 an exception is yet k- 

 though this query ha^ 

 lished far and wide £■
