During twenty years, the author thought about the physical observation of irregularity motion of the earth's crust, which showed itself the existence of the diurnal nutation. The formulae of the variations of the speed of the earth's crust in giving an older publication, he talks about his various experiences that he realized by means of a very simple device, created by the engineer A. Rouma, which is involved in no action other than gravity and inertia. Observations are sufficient to physically demonstrate the existence of the diurnal nutation, the irregularity of the motion of the earth's crust and the independence between them and the core in the short term motion.
