what letter did mr.collins write to mr.bennet

At breakfast the following day Mr. Bennet announces that Mr. Collins, a cousin of his whom he has never met, will be coming to visit. Because of the laws of inheritance at the time and because Mr. Bennet has no sons, Mr. Collins is in line to inherit Longbourn. Mrs. Bennet hates Mr. Collins because of this, but Elizabeth and Jane try to explain the nature of the laws of entailment.

To inform them of his visit, Mr. Collins writes a letter to Mr. Bennet. In the letter Mr. Collins explains that he has recently been ordained and is under the patronage of Lady Catherine De Bourgh.
