 and Mr. George Shaw, of the Stockport Technical School, 

 communicated by Mr. Thomas Kay, was read by Mr. 

 George Shaw : — " In the course of certain experiments 

 made by us in the laboratory of the Stockport Technical 

 School, with a view to the simplification of the existing 

 methods of quantitatively determining the halogens in 

 organic compounds, it was found that when such compounds 

 as chloral hydrate were passed in the form of vapour, 

 mixed with hydrogen, through a tube filled with broken 

 quartz or other inert substances, and heated to redness, 

 they were completely decomposed, the whole of the
