“You were always a careful student, and your casebook was ever more full than the rest. You were only student then; now you are master, and I trust that good habit have not fail. Remember, my friend, that knowledge is stronger than memory, and we should not trust the weaker. Even if you have not kept the good practise, let me tell you that this case of our dear miss is one that may be⁠—mind, I say may be ⁠—of such interest to us and others that all the rest may not make him kick the beam, as your peoples say. Take then good note of it. Nothing is too small. I counsel you, put down in record even your doubts and surmises. Hereafter it may be of interest to you to see how true you guess. We learn from failure, not from success!”
