There is no diminution onpressure over the tumor. It is of doughy consistenceand only slightly movable over the subjacent bone. Lipomas occurring on the forehead and having asmooth, not lobulated surface, may resemble der-moids. However, they are not congenital, have nobony ring round them, and are freely movable. Encephalocele (which may be naso-frontal, naso-ethmoidal, or naso-orbital) is also a congenital tumor,but generally attains a much larger size, diminisheson pressure, and has no bony ring round it. On account of the scar in the skin an epithelialcyst might be thought of; however, this is not con-genital but occurs later as the result of trauma. 94 Bockeiilieimer, Atlas. Tab. Fifj. 48.

The tumor has caused phi-mosis and balanitis. Fig. 48 shows a dermoid of the neck in the positionof the second branchial arch. Symmetrical der-moids in the middle line may occur above or belowthe larynx. Dermoids of the floor of the mouth maycause bulging of the sub-mental region.
