The third Angle is more acute, and long, and may be difcovered in the lower part of the Head, and tendeth downward; and as mofi of the Angles of the head of the Clavicle ( inarticulated with the Bone oi the Stanton) are obtule 5 f0 alfo are the {ides of the Triangle unequal, and run in bevil lines outward; and the Line drawn from the firl't Angle to the fecond is the {hortei‘ts and the other drawn from the Second to the and Quiet. ) And the Clavicles are articulated with the Procels of the Smpnla Jr to hip.
