acid, phosphoric acid, etc., in place of zinc chloride in the 

 last named reagent has also been studied. 



Various inorganic salts and organic compounds, in

 cotton ; the author is therefore extending his investigation 

 to these. 



It should be pointed out that these reagents may 

 prove of value in the distinction of other textile and 

 paper-making fibres, the various artificial silks, etc. 



The author hopes shortly to lay the results of these 

 investigations before the Society.
