Burroughs (Of the Mermaid and Jupiter)

 was a passenger aboard the Mermaid. He and the Seventh Doctor had several academic arguments.

After several shipwrecks, the crew of the Mermaid ended up in the water, surrounded by sharks. Burroughs started to panic, splashing violently. The Doctor hypnotised him to calm him. Burroughs and crewman Hussey, who had also been hypnotised, played quietly in the water until rescue came.

Once the crew was finally rescued, the Doctor disappeared, leaving Captain Nolbrow with an angry Burroughs. (PROSE: Of the Mermaid and Jupiter)
