Sulphurous acid (not sulphuric) will 

 often destroy the pests when other meas-

 next application, which will be from twelve 

 to twenty-four hours, according to the 

 severity of the case. 



Many persons use carbolic acid for this 

 purpose with good result, so far as destroy-

 appears to be advisable to employ this 

 agent, three drams to one quart of water 

 will be about the proper strength to use. 

 After thoroughly bathing the affected parts 

 with the solution, it should be allowed to 

 remain not more than two or three minutes,
