Here is a paragraph of recommendation.
To whom it may concern: You wrote to ask me for my opinion of John, who has applied for a position in your department.
I cannot recommend him too highly nor say enough good things about him.
There is no other student of mine with whom I can adequately compare him.
His thesis is the sort of work you don't expect to see nowadays and in it he has clearly demonstrated his complete capabilities.
The amount of material he knows will surprise you.
You will indeed be fortunate if you can get him to work for you.
