The Flea Circus Research Library's look into the microscopic world of educated and trained fleas.
Tom reports in his blog that he saw the Prof Jephcott flea circus in Regent's Park. He says that he could not see the fleas, presumably they were very small.
I feel quite bad for saying there are no fleas now! You're right of course. They are just very small, and my eyes are very bad.
Not a problem. Perhaps you could take a fresnel lens with you on your next visit.
