"The pamphlet entitled Gigan -"

He could get no further.

"Giganteo -"

It was not to be done. The unlucky word would not come out. At the Johannæum there would have been a laugh.

"Gigantosteologie," at last the Professor burst out, between two words which I shall not record here.

Then rushing on with renewed vigour, and with great animation:

"Yes, gentlemen, I know all these things, and more. I know that Cuvier and Blumenbach have recognised in these bones nothing more remarkable than the bones of the mammoth and other mammals of the post-tertiary period. But in the presence of this specimen to doubt would be to insult science. There stands the body! You may see it, touch it. It is not a mere skeleton; it is an entire body, preserved for a purely anthropological end and purpose."

I was good enough not to contradict this startling assertion.

"If I could only wash it in a solution of sulphuric acid," pursued my uncle, "I should be able to clear it from all the earthy particles and the shells which are incrusted about it. But I do not possess that valuable solvent. Yet, such as it is, the body shall tell us its own wonderful story."

Here the Professor laid hold of the fossil skeleton, and handled it with the skill of a dexterous showman.

"You see," he said, "that it is not six feet long, and that we are still separated by a long interval from the pretended race of giants. As for the family to which it belongs, it is evidently Caucasian. It is the white race, our own. The skull of this fossil is a regular oval, or rather ovoid. It exhibits no prominent cheekbones, no projecting jaws. It presents no appearance of that prognathism which diminishes the facial angle. [1] Measure that angle. It is nearly ninety degrees. But I will go further in my deductions, and I will affirm that this specimen of the human family is of the Japhetic race, which has since spread from the Indies to the Atlantic. Don't smile, gentlemen."

Nobody was smiling; but the learned Professor was frequently disturbed by the broad smiles provoked by his learned eccentricities.

"Yes," he pursued with animation, "this is a fossil man, the contemporary of the mastodons whose remains fill this amphitheatre. But if you ask me how he came there, how those strata on which he lay slipped down into this enormous hollow in the globe, I confess I cannot answer that question. No doubt in the post-tertiary period considerable commotions were still disturbing the crust of the earth. The long-continued cooling of the globe produced chasms, fissures, clefts, and faults, into which, very probably, portions of the upper earth may have fallen. I make no rash assertions; but there is the man surrounded by his own works, by hatchets, by flint arrow-heads, which are the characteristics of the stone age. And unless he came here, like myself, as a tourist on a visit and as a pioneer of science, I can entertain no doubt of the authenticity of his remote origin."

[1] The facial angle is formed by two lines, one touching the brow and the front teeth, the other from the orifice of the ear to the lower line of the nostrils. The greater this angle, the higher intelligence denoted by the formation of the skull. Prognathism is that projection of the jaw-bones which sharpens or lessons this angle, and which is illustrated in the negro countenance and in the lowest savages.

The Professor ceased to speak, and the audience broke out into loud and unanimous applause. For of course my uncle was right, and wiser men than his nephew would have had some trouble to refute his statements.

Another remarkable thing. This fossil body was not the only one in this immense catacomb. We came upon other bodies at every step amongst this mortal dust, and my uncle might select the most curious of these specimens to demolish the incredulity of sceptics.

In fact it was a wonderful spectacle, that of these generations of men and animals commingled in a common cemetery. Then one very serious question arose presently which we scarcely dared to suggest. Had all those creatures slided through a great fissure in the crust of the earth, down to the shores of the Liedenbrock sea, when they were dead and turning to dust, or had they lived and grown and died here in this subterranean world under a false sky, just like inhabitants of the upper earth? Until the present time we had seen alive only marine monsters and fishes.
