Looking back on his first year of medical practice in an out-of-the-way section of Russia, a 25 year old physician reflects on how much he has changed both personally and professionally. He lists the year's accomplishments: performing a tracheostomy, successful intubations, amputations, many obstetrical deliveries, and setting several fractures and dislocations. With pride, the doctor calculates he has seen 15,613 patients in his first twelve months of practice.

He recalls some poignant moments. A pregnant woman has a baby while lying in the grass near a stream. The doctor pulls a soldier's carious tooth but is horrified when a piece of bone is attached to it. During a delivery, he inadvertently fractures a baby's arm and the infant is born dead.

Basking in his year's worth of experience and newfound clinical confidence, the physician quickly comprehends the limits of his knowledge on the first day of his second year in practice when a mother brings her baby to the doctor. The infant's left eye appears to be missing. In its place sits an egg-like nodule. Unsure of the diagnosis and worried about the possibility of a tumor, the physician recommends cutting the nodule out. The mother refuses. One week later she returns with her child whose left eye is now normal in appearance. The doctor deduces that the boy had an abscess of the eyelid that had spontaneously ruptured.
