'"Do you smell anything, Monsieur Mailey?"
Mailey sniffed the air.
"Yes, surely, it reminds me of our London Zoo."
"There is another more ordinary analogy. Have you been in a warm room with a wet dog?"
"Exactly," said Mailey. "That is a perfect description. But where is the dog?"
"It is not a dog. Wait a little! Wait!"
The animal smell became more pronounced. It was overpowering. Then suddenly Malone became conscious of something moving round the table. In the dim red light he was aware of a misshapen figure, crouching, ill-formed, with some resemblance to man. He silhouetted it against the dull radiance. It was bulky, broad, with a bullet-head, a short neck, and heavy, clumsy shoulders. It slouched slowly round the circle. Then it stopped, and a cry of surprise, not unmixed with fear, came from one of the sitters.
"Do not be alarmed," said Dr. Maupuis' quiet voice. "It is the Pithecanthropus. He is harmless." Had it been a cat which had strayed into the room the scientist could not have discussed it more calmly.'
