A NEW INK. 35 



faith by gross injustice has been too long the disastrous 

 policy of England towards inventors. 



This is more to be lamented because, although we have 

 been called " a nation of shopkeepers," the history of 

 civilization proves us to be a nation of inventors. 



It is not our duty here to discuss the merits of Boyle's 

 powder and shell. We believe that his son is acquainted 

 with the secret of their manufacture, and may yet succeed 

 in obtaining from the War Office some result more consistent 

 than that which approved his father's invention and rejected 

 it. There are other inventions which Robert Boyle devoted 

 much time in submitting to her Majesty's Government, and 

 it is hoped that their public utility will yet be recognised. 

 Amongst them we may mention an ink which is perfectly 

 inerasable, and which successfully stood the most severe 

 tests made by the Royal College of Chemistry on behalf of 

 the Government. This ink is of great commercial value : 

 it can be used also by artists as a paint in place of sepia or 

 Indian ink, and is invaluable for important documents 

 deeds, etc., as it preserves the paper upon which it is written, 

 the unwritten portion of which might fade away, but that 

 written upon would still remain as sound as ever.
