“Eat a live frog every morning, and nothing worse will happen to you the rest of the day”. The Frenchman Mac Norton took this advice from Mark Twain quite literally. About a hundred years ago he started his magician career by eating live frogs on stage. No wonder that our cute frog on the sheet music cover seems a bit worried.

For his ‘human aquarium’ performance Mac Norton, artist name of Claude Delair, took from a fishbowl five frogs and six goldfish, and swallowed them alive one by one. Then he made a point of nonchalantly lighting a cigarette. After a relaxing moment of small talk with his audience he started to disgorge all the small animals, still alive. It is said that he could keep fish, frogs or other aquatic animals moving around in his stomach for more than two hours.
All Mac Norton’s shows centered around his stunning ability to hold large quantities of water in his stomach and to disgorge it afterwards. Sometimes he would emphasise the enormous amount of water by ordering a parade of waiters to bring him 50 glasses of it. He would then demonstrate La Fontaine: he expelled the water he had just swallowed into a delicate jet in which he washed his hands. Or he performed La douche. The water then gushed from his mouth with force, but still seemingly without effort.
In Berlin, Mac Norton did his trick with beer. Houdini who watched the show behind the scenes was not that impressed. “The filled glasses were displayed on shelves at the back of the stage, and had handles so that he could bring forward two or three in each hand. When he had finished these he would return for others and, while gathering another handful, would bring up the beer and eject it into a receptacle arranged between the shelves, just below the line of vision of the audience…”. So at least some of it was a trick.

Houdini goes further. “I remember his anxiety on one occasion when returning to his dressing-room; it seems he had lost a frog—at least he could not account for the entire flock—and he looked very much scared, probably at the uncertainty as to whether or not he had to digest a live frog.”

Mac Norton himself believed that he had an extra stomach like a cow. But more likely he suffered from rumination syndrome. This is the effortless regurgitation of undigested food from the stomach back up into the mouth. There is no retching, pain or other inconveniences as in the case of vomiting.
Thanks to the treasure trove that is Gallica, I found out that Mac Norton became the subject of medical examinations in 1912.

With radiography a doctor revealed the structure of the performer’s stomach. One would expect that he would have taken images of Mac Norton’s insides after swallowing the frogs. But no, he just made him drink some fluid and concluded that his stomach was ‘very muscular‘ and that was about it. How absolutely deceiving!
To illustrate once more that songs were made about anything, we insert a Dutch sheet music cover of a song about Röntgen’s discovery: X-stralen (X-rays). On the cover we see the first ever photograph of a human body part using X-rays. It is the hand of Röntgen’s wife on a photographic plate.


I found a similar regurgitation act from 1931 by Hadji Ali in a Spanish-language version of Laurel and Hardy’s Chickens Come Home. Enjoy and have a drink!
