Bertolotto rival in Kassel

From the "The Bavarian People's Friend,Volume 17, 1840" and "La Fame" - Journal of science, literature, arts,. industry and theaters 1840.

Bertolotto, the flea tamer has found a rival in Kassel. Hr. Fiarenzi from Genoa announced, that he had trained "ants", taught them to march in rank and file, to climb scaling ladders and conquer a fortress, which was built of sugar; also, they were, on word of command’ able to retreat before the heat of a fire, while saving oats, crumbs of bread and small cut off pieces of cheese, with the result that they looked, in this way, like people who salvaged their belongings "under their arms" from the fire;

People still say that the present century had produced no great men: Bertolotto and Fiarenzi eclipse the finest intellects of all time.

The Abbot and the Flea

From Aesop's Fables there is a tale about an Abbot and a flea.

This is the story of the flea that was caught by the abbot. The abbot said, 'Now I've got you! You have bitten me many times, making it impossible for me to get a good night's sleep. I will never let you go; in fact, I am going to kill you right now!' The flea said, 'Holy Father, since you intend to kill me, please hold me in the palm of your hand so that I will be able to freely confess my sins to you. Let me make my confession, and then you can kill me.' The abbot was moved by the flea's piety so he placed the insect in the middle of his palm. The flea immediately leaped up into the air and flew away. The abbot yelled loudly at the flea, but the he refused to come back.

Flea foot power transfer

The mystery of how fleas jump resolved thanks to Professor Malcolm Burrows and Dr Gregory Sutton from the University of Cambridge Department of Zoology.

Back 1967, Henry Bennet-Clark made the discovered of resilin, the 'elastic' protein that fleas use to store the energy for jumping, however since then flea scientists have been debating how that energy was transferred into the ground to allow the flea to reach such speeds and hights.



The Cambridge scientists used low light conditions which kept the fleas calm whilst they setup the cameras then turned up the lighting to see them jump. The videos were analysed and mathermatical models were used to predict the results.

Sutton and Burrows suspected that the insects push down through the tibia (shin) onto the tarsus (toe). Using a mathematical model that could reproduce the flea's trajectory, the scientists were able to confirm that the insects transmit the force from the spring in the thorax through leg segments acting as levers to push down on the tarsus (toe), solving the 44 year old mystery.

A flea in her ear - La Puce à l'oreille

The Old Vic is showing a new play called "A flea in her ear". I say new but it was actually written in 1907 by Georges Feydeau. The play is a translation of a French Farce and from what the reviews are saying it's worth going if that's your cup of tea.

What interested me was the phrase, "a flea in her ear", according to one user on WordReference it's an old idiom going back to at least the mid-fifteenth century. Yahoo answers suggests, the real meaning of "mettre la puce à l'oreille" is "to arouse someone's suspicion", "plant the seeds of doubt", which sounds about right. There are suggestions in the press that the phrase is connected to "bee in her bonnet" which I have to disagree with although the free dictionary does suggest an alternative use of that phrase which is consistent with "A flea in her ear".
