Description

Schunck writes: 'In Parts I [see PP/7/13] and III [see PP/12/31] of this memoir I gave an account of the action of aqueous alkalis on phyllocyanin, and of the products thereby formed. By the action of caustic alkali in a state of fusion phyllocyanin undergoes a more profound decomposition, leading to the formation of several products, one of which I shall now describe.'
