Important Quotations

"I sometimes think if we knew all, we should be more glad to get away." - Dr. Lanyon

This explains that when Lanyon finds out what Jekyll has been up to, he no longer wishes to live.  The immorality of Jekyll's experiment was to much to bear for Lanyon, and he was sad that his long time friend was just not the same person that he used to be.  This is a sad realization of the truth for Lanyon, who sees that he can no longer be happy in this life, and that his time with his friends are over.

"Here, then, as I lay down the pen, and proceed to seal up my confession, I bring the life of that unhappy Henry Jekyll to an end." -Henry Jekyll

These final words of Henry Jekyll ultimately show that his experiment was a failure.  His attempt to isolate the bad in him in order to lift a burden off of his soul ended up bringing him sadness in the end.  His greed to become free of pain would cost him his life, and the sad realization that the mistake of Edward Hyde would be his last.

"I was stepping leisurely across the court after breakfast drinking the chill of the air with pleasure, when I was seized again with those indescribable sensations that heralded the change..." -Henry Jekyll

Here Jekyll finally understands that he cannot control his transformations into Hyde anymore.  He no longer is deceiving himself that he can keep it under control, and he realizes that he can no longer deceive his friends as well.  Shortly thereafter he writes his confession in his final moments as Henry Jekyll.  He was simply joking himself from the beginning that he could make this creation of evil work.
