(10) Two yellow crystalline substances in very small amount, both of which melt at about 267°, and also a trace of a crystalline sub- stance melting at 1230 C. (11) A glucosidal substance which could not be isolated, and which, besides glucose, yielded only indefinite hydrolytic products. (12) Glucose (chiefly the inactive form).
