Jrnl. 21 227 Many substances..possess the power of exercising upon compound bodies an influence essentially distinct from chemical affinity, an influence which consists in the production of a displacement, and a new arrangement of their elements, without their directly and necessarily participating in it... In defining it a new power..I shall designate it..the catalytic power of bodies; and the decomposition it produces I shall call catalysis.
