I'm going to analyse a letter  who is written by Lady davers ,sister of Mr B. to him.The letter is casually discovered by Pemela.

In the letter come to surface the difficulty of aristocracy to accept the marriage between poor people and people of high classes.

Lady Davers writes the letter for his brother and the readers know the events through what she writes , and through her point of view.In the first lines Lady davers seems to be very worry and anxious for her brother and she explains why she decides to write a letter.

She comes to know something that his brother has done through some people. She says that they are  warry for his honour.She explains her incredulity" could I think.." of what his brother can do.She doesn't want to believe that he can run away with a maid.

She demonstrates her despise for Pamela ,for her social class and  calls her "wench" ,for Lady Davers her brother has only two possibilities if he does not refuse her: either he will have her for a kept mistress, or for a wife. She invites her brother to let Pamela in peace and she provides the reader three important argumentations to support her invitation. Lady Davers  says :"the girl was an inocent ,good girl ;but I suppose that's over with her now,or soon will."there is a sort of irony in this phrase, before she despise Pamela  calling her "wench",after she says she is a good girl ,but immediately she turns back and she says that "that's over with her now.."

She tries to find some motivation to persuade his brother not to marriage Pamela and she tries to make him feel guilty.she reminds to his brother their power and the importance of their family and she doesn't want that something ruin it and that her brother can have how many woman that he wants because he has been sought to by some of the best families of nation.The function of the letter for Mr B' s sister is to make her point clear about the situation.

The second part of the letter  is a consequence of the first part . The second part deals with Pamela's letter to her parents in which the most important theme is the relation  between poor and rich.Immediately she gives  her opinion: " we were all on a foot originally", she wants to say that they are all the same.  There is an religious argumentation ,she uses the simple past ,there is an allusion of the original purity, so the readers cames to know her religion : The Puritanism. Who is based on the  necassity to find the original purity. She sees the aristocratic as a spring of sin. She makes a comparison between the blood of the aristocratics and poor people. Both  they have a untained blood ,it is unless that this gentry brag of their blood because is the same of poor people.  After that there is a reference to the brevity of life , and with this phrases:" with all their vanity a time.." Pamela wants to say that death doesn't watch nobody in face, if she must to arrive she arrives without informing  and she makes they on a level with the poor people.With this phrase the reader understands her desire to submit the aristocracy.  A philosopher said that he saw no difference between the skull of a king and that of a poor people. There is a reference to the monologue of Hamlet. When you died you are as the other people, we are tie of the same destiny : the death. It isn't important what you were in life when you die because you die even if you were a princes or beggars.In the last part of the letter Pamela explains the function of her reflections because she says they occurred to her thoughts.She calls Lady Davers "lowly" and herself "high-minded",She calls Mr B's sister lowly because she is proud of her noble gentry and she defines herself high-minded because she hopes she is too proud "ever to do the like".At the end she explains  the situation of poor people but with the last sentence she communicates her pray to be kept from the pride of a high estate.
