    CHAPTER IV DURATION OF APPLICATIONS So many considerations have to be taken into account in determining the duration of applications that it is difficult to give any precise information. Account must be taken of the age of the patient, nature and depth of the disease, strength of the radium prepara- tion, and the presence or absence of screens. I have found that 10 milligrammes of the pure bromide in an ebonite case with a mica window can be applied for about thirty minutes to a capillary nevus on a baby’s face, and for about fifty minutes to an adult's face, without provoking too much irritation. On the other hand, if a piece of silver 2’ millimetres thick be interposed, the same specimen can be left on three or more hours; using a lead screen one or two millimetres thick, an eight hours’ application can be made. Care should be exercised as to repeating an applica- tion to a spot already treated, for it will produce far more reaction. In some cases it may be an advantage, and insome » it may be necessary, to maintain the radium at a little
