C70 TRANSACTIONS OF SECTION H. 



the Author made further experiments on these lines, and found that the presence 

 of oxygen and v/ater was of importance This led to the gradual reduction of the 

 quantity of hydrogen, and finally to its complete omission ; but the periodical 

 necessity of reducing the iron used for the purposes of moist oxidation led him to 

 employ some carbonaceous material (coke, cdal, charcoal, &c.), for this purpose. 



Finally peat was found to give the most satisfactory and rapid results, and 

 even when it contained up to 80 per cent, of water it could be utilised advan- 

 tageously. 



In the meantime experiments were made to prove the co-operation of atmo- 

 spheric nitrogen. Sugar carbon absolutely free from nitrogen was treated by the 

 process and produced an average of 1 percent, ammonia on the carbon consumed. 



The large plant erected at Carnlough, co. Antrim, has finally confirmed the 

 working and results of the process on a commercial scale.
