The main idea of the ''fejee mermaid'' supported by paragraphs 8 through 10 is that Barnuim wrote an newspaper about ''fejee mermaid'' to help build his ''mermaid fever'' in new york'' . Barnuim's friend ''dr.griffin'' and him made a hoax according to the passage''Barnuim made his hoax more belivevable by haveing a ''scientist'' present it.''.the main idea is that barnuim and his friend lied to the people believing that the ''fejee mermaid'' is real.
Obviously mermaids are not real, I thought the school was only suppose to teach you real things or fake things but any way the main idea is that she was able to find her parents in the shore and live happily ever after
