 clogging. The saturator needs only occasional replenishing. With due attention to these 

 directions and the ordinary prudence which must at all times be exercised in the use of 

 highly explosive substances, this lamp is capable of affording a brilliant and satisfactory 

 light, with perfect safety to the operator and a minimum of expense and trouble. The 

 cost of operating the lamp, so far as can be determined from present experience, is about 

 fifteen cents per hour. 



The apparatus is patented in Europe and America.
