Note the comma added and the spelling corrected.

1) The first sentence seems grammatically correct and accurately describes a key moment in the story of Dr. Jekyll and Mr. Hyde. It mentions that Dr. Jekyll comes to realize the duality of man and admits that man is not one but two. However, there is a question mark after "human soul" which suggests uncertainty about whether this term is appropriate.

2) The second sentence states that Dr. Jekyll believed that if he could separate his two identities, he could live both lives without guilt or shame. This sentence conveys Dr. Jekyll's motivation for seeking a solution to his inner conflict.

3) The third sentence talks about how even before his scientific discoveries, Dr. Jekyll had daydreamt of separating the two natures of the human soul into separate identities – one good and one bad. This sentence provides some background information about Dr. Jekyll's long-standing desire to explore the duality of human nature.

4) The fourth sentence seems incomplete and lacks clarity. The purpose of using the particular salt is not clearly stated. To improve this sentence, it would be helpful to add more information about what Dr. Jekyll intended to achieve with this salt or how he planned to use it.

5) The fifth sentence describes Dr. Jekyll's experience after consuming the potion he created. He undergoes intense physical and mental distress, including racking pangs, bone grinding, nausea, and a horror in the spirit. This sentence captures the severe consequences of his experiment.

6) The final sentence explains that after the agonies subsided, Dr. Jekyll regains consciousness and feels as if he is emerging from a severe illness. This sentence highlights the aftermath of his experiment and sets the stage for further developments in the story.
