Jekyll and Hyde Dualties

How does Stevenson do it

1. The changes in Mr Utterson's character
2. The setting - in the front and back of Jekyll's house, Cavendish Square and Soho.
3. The language:
- scientific, clinical language of the murder case and then the romantic flowery language of the maid.
- The changes in Jekyll's language as he becomes more despairing.
- Changes in Hyde's and Jekyll's dialogue
4. Good actions of Jekyll and the evilness of Hyde.
5. Appearance of Jekyll and Hyde.
6. Acting morally and avoiding scandal (Utterson)
7. Jekyll appearing to do good work but no taking responsibility for Hyde's actions.
8. Lanyon's dismissal of Jeykll's discoveries as “unscientific balderdash” (rational man of science) contrasting Jekyll's language
9. Jekyll and Lanyon both leave letters which records everything they have seen and done but insist that these records not be opened until after their deaths - suggesting a reliance on reputation.
10. Jekyll’s guilt and Hyde’s apathy/indifference
11. Hyde's appearance and actions - but his furnishings and dialogue are quite refined.
12. Jekyll's repression and Hyde's outright actions.
13. The fog and mist symbolising Jekyll's hidden identity.

14. Chapter Two - Duality of Utterson's rational thoguhts and reporting but with a supernatural dream sequence.
15. Jekyll's house is a mansion with "a great air of wealth and comfort" that is secretly connected to the doctor's laboratory. The laboratory front (chapter 1) appears run down and neglected, and can be entered through the mysterious door described in the first chapter. we learn later that the laboratory is in fact where Dr. Jekyll undertakes his transformations into Mr. Hyde.
16. Chapter 4 - Utterson appears immediately when summoned by the police, and provides them with a great deal of information in order to find the murderous Edward Hyde. However, he stops short of telling the police of the connection between Hyde and Dr. Jekyll.
17. Utterson loyally protects his friend throughout, in contrast, Jekyll lies to Utterson, defending Hyde with a fake letter. (Chapter 5)
18. Lanyon's belief in logic and sound science is proved wrong and the supernatural starts to take over.
19. Mirroring of Chapter 1 with Chapter 7 (they start in the same way)
20. Chapter 7 contrasts chapter 8 with lack of action and lots of action.
21. The religious work that Jekyll held in great esteem that has been, "annotated in his own hand with startling blasphemies."
22. Even after witnessing death and highly strange events, Utterson wishes to delay involving the authorities in an attempt to save face.
23. Although Lanyon is very detailed in what he witnessed that night, he does not provide an explanation of how such a transformation could occur, or how Jekyll's scientific experiments advanced and progressed to this point.
24. The contrast between third and first person narrative.
25. In his letter, Jekyll clearly states that he felt no guilt about Hyde's actions, as "Henry Jekyll stood at times aghast before the acts of Edward Hyde, but the situation was apart from ordinary laws, and insidiously relaxed the grasp of conscience. It was Hyde, after all, and Hyde alone, that was guilty." To the reader, this explanation seems ridiculous, because Hyde is in fact part of Jekyll, and a being that Jekyll created.
26. The noble Utterosn lives but Jekyll/Hyde dies.
