DISEASES OF BONE All varieties of bone disease are met with in the radiographic examinationof the bones, it being possible to trace the progress of disease from the slightestbeginnings to the most advanced stages. A thorough appreciation of thenormal appearance of bone is necessary before we can make out departuresfrom it. Good negatives are essential, that is, the negative must show thefiner detail as well as the outline of the bone. Soft tubes give better platesfor this purpose than hard ones, but the exposures require to be longer, and
