An American text-book of the diseases of children .. . her on the concave aspect ofthe curvature, and of normal thickness or thickerthan normal upon the convexity. The accompany-ing wood-cut exhibits the appearance and nature ofrachitic spinal curvature continuing into adult , having occurred at the usual age, resultedin the permanent deformity here illustrated. In extreme cases, fortunately rare, the functionsof important organs may be seriously impaired bythe curvature and consequent compression, as they arein Potts disease. Thus, according to Miller, the aortahas been so doubled upon itself as to materially dim-inish the flow of blood to the lower extremities, so thattheir nutrition was sensibly impaired. The effect of sogreat curvature upon the heart and lungs must obvi-ously be detrimental. At first the spinal curvaturesdisappear when the child reclines or is lifted by theaxillae so as to raise the head and shoulders from the spine; but when thedeformity has continued so long that the vertebrae and cartilages have become.

As seen in the wood-cut, the commoncurvature in the dorsal region is backward (kyphosis), while to compensatethe patient instinctively carries the neck forward, with the head thrown back,causing cervical lordosis, a similar anterior curvature being common in thelumbar region. Lateral curvature (scoliosis) may or may not be present evenwhen there is considerable antero-posterior flexure. Scoliosis is sometimesproduced by the nurse in carrying the infant habitually over one arm. Changes in the Maxillce.—Fleischmann has investigated the changeswhich rachitis produces in the maxillary bones. Stunted growth of the facialbones, generally, has long been known, and has been remarked upon
