    pupils are equal and of natural size. The right radial pulse was stronger than the left when first examined. The swelling of the left carotid artery (the coats of which feel much thickened) involves the upper half of the vessel. Its prominence is very marked about two inches below the ramus of the jaw, as is also the loco- motion of the artery, which here advances at each diastole with a rapid and very forcible forward pro- jection alongside the tracheal edge of the left sterno- mastoid muscle, and then as rapidly retreats during the succeeding systole. The tracing of its impulse has been taken by Dr. Hawksley with his stetho- sphygmograph, as also those of both radial pulses. The latter agree in every particular with those taken at the hospital. A pulsating swelling, about the shape and size of a date, is visible, emerging from behind the right sterno-clavicular articulation, and occupying the hollow of the neck. It extends up- wards from beneath the inner head of the sterno- mastoid muscle to its outer head, taking a somewhat oblique direction. The impulse is strong, expansive, and liquid during arterial diastole; during systole the swelling perfectly subsides. The heart appears to be displaced horizontally; its apex is situate near the fourth rib, one inch above the left nipple; and there is dilated hypertrophy of the left ventricle. The car- diac impulse is synchronous with that of the tumour and of the radial pulses. No thrill anywhere exists. The right radial pulse, formerly strongest, has ap- F
