6. Read no letters, books or papers in company; but when there is a necessity for doing it, you must not leave. Come not near the books or writings of anyone so as to read them unasked; also look not nigh when another is writing a letter.

12. When a man does all he can though it succeeds not well, blame not him that did it.
13. Being to advise or reprehend anyone, consider whether it ought to be in public or in private, presently or at some other time, also in what terms to do it; and in reproving show no signs of choler, but do it with sweetness and mildness.

15. se no reproachful language against any one, neither curses or revilings.

18. Play not the peacock, looking everywhere about you to see if you be well decked, if your shoes fit well, if your stockings set neatly and clothes handsomely.
19. Associate yourself with men of good quality if you esteem your reputation, for it is better to be alone than in bad company.

42. Be not tedious in discourse, make not many digressions, nor repeat often the same matter of discourse.
43. Speak no evil of the absent, for it is unjust.
