<p style='text-align: justify;'>Letter from an ophthalmologist to his former assistant. He blames his knowledgeable assistant (who was also his relative) for having left without giving him details about the various medications in the dispensary and asks him to return to work. The assistant seems to have left saying that his master had not given him enough time to pray. The writer sends two eye salves and other items with the letter, asking the former assistant to identify them. He also says that he has heard that their mutual acquaintance, Menaḥem, has become a licensed physician but that the former assistant had not yet achieved that status. He advises the assistant to study a book on ophthalmology by Daniel b. Šaʿyā.</p>
