Chasing the Industrious Fleas

Whilst researching the history of the Flea Circus, I perioducally do a search for "Flea Circus", "L Bertolotto" or "Industrious Fleas" in both the google search and the google books search. The book search returns an increasing number each time I run it. Many of these are simply references to politics or cheap jokes about badly run guest houses.

However, today I found a couple of new links including

The diary of Lord William Russell and his wife, 1815-1846
The life and adventures of George Augustus Sala

Which are present in local libraries to me. So there could be some intersting progressions soon....
