At a meeting of theLondon Pathological Society, reported in the Lancet for November, 1880, Dr.Lees presented statistics to show that craniotabes is one of the lesions of inher-ited syphilis; but whether it does sometimes result from inherited syphilis ornot, the evidence that there is a cranial softening which is strictly rachitic, andwhich occurs in those who have not inherited syphilis, appears from reportedobservations to be conclusive. Changes in the Vertebras, etc.—The short bones which participate inthe rachitic disease become softer and more yielding, and their cancelli are filled RACHITIS. 349 with a reddish pulpy substance. In many rachitic cases the vertebrae are butslightly involved, so that no deformity of the spinal column results; but occa-sionally, when many bones are affected, the vertebrae and intervertebral carti- Fio. 2.

When there is much curvaturethe vertebrae become wedge-shaped, narrowed upon theconcavity and thickened upon the convexity. The in-tervertebral cartilages are also more or less changedby the pressure, being thinned where the vertebraeapproximate to each other on the concave aspect ofthe curvature, and of normal thickness or thickerthan normal upon the convexity.
