      J. W. Thomson (H. P., xvi.32) reports the case of a gentleman., aged 84, who had severe neuralgic pains between posterior of right ear and center of occiput.
      From this he apparently recovered.
      Eighteen months later he returned with a steady, sore, and burning pain in same region, swollen and tender around, but especially behind, right ear.

      Sweat afforded no relief, the whole head seemed to sympathize with the distress, he had dribbling of urine.
      Formica rufa was given, six doses, one before each meal.
      On the second day, towards evening, he felt worse, and on the third day there were twinges and spasms of severe pain in addition to the sore pain which he had before experienced.
      These gradually got better, and on the fourth day even the soreness was much better.
      The main thing, however, was that he felt mentally better, said his mind and head felt stronger, and from feeling depressed he had become cheerful, and life did not seem the burden it had for some time past.
