This malady is often troublesome, not so much from its severity, as from its persistence and great tendency to relapse, and Mr. Balman, has written to praise phosphoric acid, not only in struma, but especially "in the intermittent ophthalmia of a scrofulous constitution": he says that, given in doses of from 5 to 20 min. in cal-umba, the acid both cures and prevents recurrence of the affection (London Medical Gazette, August 22, 1858).
