Doctor Gregory read a paper, entitled, ‘‘ Examination 
of Eblanine, a substance discovered by Mr. Scanlan, and 
exhibited by him at the Meeting of the British Association.” 
By Professor Apjohn and Dr. Gregory, 
Eblanine is contained in pyroxilic spirit. It is yellow, 
crystalline, fusible at 318°, volatile in a current of air at 300°, 
not subliming in a close tube unchanged. It is insoluble in 
water and alkalies, soluble with a strong yellow colour in‘ 
alcohol, ether, and concentrated acetic acid. Strong sul- 
phuric acid strikes with it a deep bluish purple colour, soon 
passing to brownish black. Strong muriatic acid dissolves 
it sparingly with a very fine and intense purplish red colour, 
which also slowly passes into brownish black. Nitric acid 
dissolves it, and from the solution water separates a yellow 
solid, which, at a certain temperature, is decomposed sud- 
denly with a very feeble explosion. Chlorine converts it 
into a dark resinous matter.
