    RELATIVELY SYMMETRICAL forms of the ab- normal chest. THE PIGEON BREAST deformity of the chest occurs chiefly in childhood^ and is characterized by lateral constriction of the thorax, with straightening of the true ribs and prominence of the lower end of tlie sternum ; this is a result of rhachitis. THE RHACHITIC CHEST is de^veloped in early life ; it is characterized by lateral retraction of the thoracic walls, the anterior surface being broader than in the pigeon breast, and the sternum less prominent; the costo-chondral junctions are thickened, pre- senting a series of bead-like eminences known as the rhachitlc rosary, THE ALAR CHEST is characterized by ving-Iihe pro- jections of the scapulae, usually associated witli a^ narrow chest, sloping shoulders, and an acute costal angle. It is commonly significant of constitutional weakness, which favors the development of pul- monary phthisis. THE EMPHYSEMATOUS OR BARREL-SHAPED CHEST is characterized by roundness of contour, the antero-posterior diameter being lengthened, the transverse diameter shortened, and the upper end of the sternum prominent; the intercostal spaces are wide and full, the shoulders are thrown for- ward, the scapulae separated, and the whole pos- ture stooping. FUNNEL BREAST, characterized by sinking in of the lower end of the sternum, is a congenital deformity sometimes observed in several branches of the same family ; it may be so marked as to interfere seriously with respiration. Shoemakers^ breast is an acquired deformity of similar form, and is caused by the pressure of tools against the lower part of the sternum.
