But more was to come, when, with a rush through clouds of bone dust, he laid his hand upon a bare skull, and cried with a voice trembling with excitement:

"Axel! Axel! a human head!"

"A human skull?" I cried, no less astonished.

"Yes, nephew. Aha! M. Milne-Edwards! Ah! M. de Quatrefages, how I wish you were standing here at the side of Otto Liedenbrock!"

CHAPTER XXXVIII.

THE PROFESSOR IN HIS CHAIR AGAIN

To understand this apostrophe of my uncle's, made to absent French savants, it will be necessary to allude to an event of high importance in a palæontological point of view, which had occurred a little while before our departure.

On the 28th of March, 1863, some excavators working under the direction of M. Boucher de Perthes, in the stone quarries of Moulin Quignon, near Abbeville, in the department of Somme, found a human jawbone fourteen feet beneath the surface. It was the first fossil of this nature that had ever been brought to light. Not far distant were found stone hatchets and flint arrow-heads stained and encased by lapse of time with a uniform coat of rust.

The noise of this discovery was very great, not in France alone, but in England and in Germany. Several savants of the French Institute, and amongst them MM. Milne-Edwards and de Quatrefages, saw at once the importance of this discovery, proved to demonstration the genuineness of the bone in question, and became the most ardent defendants in what the English called this 'trial of a jawbone.' To the geologists of the United Kingdom, who believed in the certainty of the fact—Messrs. Falconer, Busk, Carpenter, and others—scientific Germans were soon joined, and amongst them the forwardest, the most fiery, and the most enthusiastic, was my uncle Liedenbrock.

Therefore the genuineness of a fossil human relic of the quaternary period seemed to be incontestably proved and admitted.
