Answer:
Major Kovaloff's nose.
Step-by-step explanation:
In this story, Gogol tells us that Ivan Jakolevitch, who was a simple barber, found a nose in his breakfast bread. We learn that the nose belongs to Major Kovaloff. However, throughout the story, as Major Kovaloff tries to recover the nose, the reader is never informed of why the nose ended there, or why the Major lost it.
