Yellow elastic fibrous tissue is notunfrequently mingled with the white. Beside these elements,fibrous tumours contain blood-vessels which are sometimes verynumerous; but no other tissue in large quantity. Tumours corn-.

The texture of true fibrous tumours is firm and tough,often grating under the knife; their surface is glistening andsmooth; the colour white, reddish white, or greyish red. Littlefluid is seen on the cut surface; what there is, is usually generally yield gelatine on boiling. In size they vary verygreatly; some are extremely small, while some have been seen af;-ot or more in diameter, being among the largest of all differ much in their degree of connection with neighbouringparts, being sometimes blended with these by continuity of tissue,but more often separated by a clear line of demarcation. Fibrous tumours develop themselves in very different parts ofthe body; usually in su
