Just received a great recommendation letter with one incident of a different student name In reviewing graduate school applications, I have a letter of recommendation that consists of two paragraphs. The first one is very detailed and personalised. The second one I think is standard and used for all students. The problem is that on the second paragraph, another name is used. I guess the professor copied and pasted it from another letter of recommendation and forgot to correct the name. 

How do I ask the professor, politely, to change that name?
No need to be anything but simple, polite, and direct:


  Dear Professor Careless:
  
  Pardon me, but the second paragraph of your letter has the name of a different student, which I assume to be a mistake.  Would you care to provide a corrected version of your letter?
