The monoplane presented in 1914 has been built in 1918. With a propeller in the middle of the fuselage. The picture seems on the Web already but the link does not work for me.

The Bird on your pic is the de Monge Biplane from 1918. I post the Monoplane 1914.

Any info on this strange "automatically stabilized" De Monge prototype with 150 hp Hispano-Suiza engine?

This is the de Monge-Buscaylet Experimental aircraft from 1918.
"In 1918 de Monge designed an unusual airplane for the Buscaylet firm. It was a single-bay biplane with a living wing. Presumably this meant that the forward-swept upper wing was fully articulated. The engine was mounted inside the Deperdussin-designed fuselage and drove a propeller behind the wings. It is not known if the aircraft ever flew."

Good research, hesham,
it would be interesting nevertheless, where you found that photo with its caption.

Thank you my dear Jemiba,

it's only the rest of my memory,the most of it is gone :D

And for the source, French Aircraft of The First World War.
 
Another version of the same photo also appears in the SDASM archives on Flickr, and was also apparently mislabeled when it was first uploaded, judging from the tag words and comment.
The machine was identified on theaerodrome.com by contributor R. Bailey as De Monge-Buscaylet experimental, 1918.

De Monge was already working on the question of automatic stability of aircraft before World War I, as evidenced by this reference:
Les Expériences de Pégaud et la stabilité automatique, par Louis de Monge. La Conquête de l'air, Bruxelles, Jan. 1, 1914, v. 11, no. 1, p. 5-6.

In 1914 he built his first prototype with an automatic stability device (see attachment):
The "De Monge" monoplane, the work of a Belgian inventor, tested successfully at the Buc Airfield (Versailles). Thanks to its spring-attached aileron device, he achieves the long sought-after dream of automatic stability.

De Monge patented his invention a few months later, as seen in "Liste des Brevets relatifs à l'Aéronautique délivrés en France du 1er Juillet 1914 au 15 Octobre 1915":
475663. — DE MONGE DE FRANEAU. — Dispositif de stabilisation absolue pour aéroplanes.

Thank you.

Is that a radiator on the front or some sort of annular wing/control surface?
