If nothing is seen on the plate at the end of development that maybe considered evidence of a calculus intensify the negative and let itdry.

If this discloses anyspecks which may be suspicious repeat the exposure with such modi-fications as appear indicated by the result of the first attempt. Whenthe shadow of the calculus is seen on the plate the diagnosis is posi-tive. When several plates give clear definition of the field with-out suspicion of stone, and especially if outline of the kidney is secured,the diagnosis is negative.
