38. In visiting the sick, do not presently play the physician if you do not know therein.
44. When a man does all he can though it succeeds not well blame not him that did it.
48. Wherein you reprove another be unblameable yourself; for example is more prevalent than precepts.
50. Be not hasty to believe flying reports to the disparagement of any.
73. Think before you speak pronounce not imperfectly nor bring out your words too hastily but orderly & distinctly.
110. Labor to keep alive in your breast that little spark of celestial fire called conscience.
