In a late report made to the French Emperor on the Permanent 



arts and manufactures of France it is stated, that a grand f.l^c^Ve.'fd'ia^ 



improvement has been made in calico printing by the d'ls- France, 



covery of a permanent green. The English are represented 



as having offered great rewards and sought in vain for this 



process, which France has had the honour of discovering, 



and the advantage of which she alone will enjoy. It is now 



nearly two years since Mr. Ilett of Stratford took out a 



patent for a mode of producing permanent greens on linen 



and cotton by a process in all probability the same as that probably of

alluded to in the Trench report; for the English journals, 



in which Mr. Ilett's specification was given, must have 

 made his process known in France. Shortly after the in- 

 troduction of Mr. Ilett's colour, we understand a Mr. 

 Thomson, a calico printer in Lancashire, discovered a mode 

 of producing a permanent green on linen and cotton at one 

 application, by a process entirely different from that of Mr. 

 Ilett, in as much as it is compatible with all the various 

 systems of colours afforded both by madder and weld. 

 This last process supplies a great desideratum in the art of 

 ''aljco printing, and is capable of extensive apprKatioii.
