1. what does the creature find in the pocket of a dress (lab coat) that he had taken from

his creator's laboratory?

He found the journal in which Victor had kept during his process of creating him.

Explanation:

Mary Shelley's gothic novel "Frankenstein" tells the story of the misfortune of not only the created monster but also of the creator Victor Frankenstein. This  story revolves around the monster's attempts to gain the love and trust of his creator, and the subsequent suffering both had to suffer.

After Victor first saw the monster, he became so repulsed with it that he immediately ignored it and wanted nothing to do with it. He then went away, wherever that will be farthest for him to be away from the creature. One day, when he was rummaging through the old coat of his creator, he found an old journal that Victor kept during his creation/experiment inside the pocket. When he read it (fr by this time he had taught himself to read and write and even speak), he learned that Victor had hated him. The despair that he felt in seeing his creation only led the monster feel more hatred in knowing that even his own creator doesn't want him. Thus, this began the hatred he began to maintain for his creator/father Victor Frankenstein.
