 from Lightning. 



The Lightning Dispeller. 



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



The Patent Lightning Dispeller is a conduc- 

 tor specially designed to dissipate the energy 

 of 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. 



Correspondence solicited. 



AGENTS WANTED. 



Tlie American Lightning Protection Company, 



United Bank Building, Sioux City, Iowa. 



PROTECTION FROM LIGHTNING. 



All the capital desired for the parent company 

 to handle my patents on a new method of protect- 

 ing buildings from lightning has been subscribed. 

 Sub-companies and agencies to introduce the 

 invention are forming, and any desirous of tak- 

 ing State-rights should address The American 

 Lightning Protection Co., Sioux City, Iowa. 



The English patent is lor sale, and offers 

 an excellent opportunity for the formation of a 

 company now that the American company is so 

 favorably started.

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 light- 

 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. 



First inseited Jui.e ig. No response 

 to date.
