Thepatient is a woman of fifty-one apparatus used for making thisplate was installed in Ancoats Hospi-tal, Manchester, England, in 1907. It was the first x-ray plant in Man-chester and is still in use. The techniqueused for making this plate was a six-teen inch coil with a mercury gas breakwith exposure of one second, usingduplitized film and intensifying Radiography of the Os Calcis D. RAY A. WATTERS, B. S., A. M, University, Atlanta, Georgia |T IS the purpose of this paper, inthe following series of radiographicreproductions of the os calcis, to illus-trate what seems the simplest, mostreliable, and easiest method of securingx-ray plates of this particular part ofthe human anatomy. The necessity ofa position has a great deal to do withits invention; but the necessity for se-curing a normal x-ray shadow shouldstimulate a certain amount of cautionthat the position will not be overesti-mated. The x-ray plate should present apicture of such clearness and detail asto make the pathology easily seen. Inother words, the picture presented tothe roentgenologist should be normal incontour, which is of the utmost value indetermining both the normal and thepathological structure. There are timeswhen the technician finds radiographyrather problematic from the standpointof abnormal rather than normalshadows. A normal shadow is essen-tially
