The doctor tends to Niggle at the Workhouse. When Niggle first arrives, the doctor treats him harshly, prescribing bitter medicine. But at the end of Niggle’s time in the Workhouse, the doctor gives him a bottle of tonic, some salve for his hands, and a train ticket. The doctor’s character is a vehicle for Tolkien to demonstrate that Niggle’s endurance of rough treatment is rewarded by gentleness.
