2 Drops Every 4 Hours

My family physician told me of an incident that
actually happened to him back in the early days
of his practice.

He said a woman brought her baby to see him,
and he determined right away that the baby had
an earache.  He wrote a prescription for ear drops.
In the directions he wrote, "Put two drops in right
ear every four hours" and he abbreviated "right"
as an R with a circle around it.

Several days passed, and the woman returned
with her baby, complaining that the baby still had
an earache, and his little behind was getting really
greasy with all those drops of oil.

The doctor looked at the bottle of ear drops and
sure enough, the pharmacist had typed the
following instructions on the label:

"Put two drops in R ear every four hours."
