Forester dressed himself as fast as he could, and followed Archibald through a long passage, which led to a back staircase. "Do you hear the noise?" said Archibald. "Not I," said Forester. "Well, you'll hear it plain enough presently," said Archibald: "follow me down-stairs." He followed, and was surprised, when he got into the hall, to find all the family assembled. Lady Catherine had been awakened by a noise, which she at first imagined to be the screaming of an infant. Her bedchamber was on the ground floor, and adjoining to Dr. Campbell's laboratory, from which the noise seemed to proceed. She awakened her son Archibald and Mrs. Campbell; and, when she recovered her senses a little, she listened to Dr. Campbell, who assured her, that what her ladyship thought was the screaming of an infant was the noise of a cat: the screams of this cat were terrible; and, when the light approached the door of the laboratory, the animal flew at the door with so much fury, that nobody could venture to open it. Every body looked at Forester, as if they suspected that he had confined the cat, or that he was in some way or other the cause of the disturbance. The cat, which, from his having constantly fed and played with it, had grown extremely fond of him, used to follow him often from room to room; and he now recollected, that it followed him the preceding evening into the laboratory, when he went to replace the skeleton. He had not observed whether it came out of the room again, nor could he now conceive the cause of its yelling in this horrible manner. The animal seemed to be mad with pain. Dr. Campbell asked his son whether all the presses were locked. Henry said he was sure they were all locked. It was his business to lock them every evening; and he was so exact, that nobody doubted his accuracy.
