It is obvious, from the preceding specimen, that a conventional catechism involving every object can be contrived by two persons, and adapted to every circumstance. The striking performances of the most notorious mesmeric 'patients' in this line prove the possibility of the achievement. The 'agent' who receives the questions in writing or in a whisper thus communicates the answer to the patient, who is laboriously trained in the entire encyclopaedia of 'common things' and things generally known; but it MAY happen that the question proposed by the spectator has been omitted in the scheme. On one occasion, when the famous Prudence was the 'patient,' and was telling the taste of all manner of liquids from a glass of water, I proposed 'Blood' to the 'agent.' He shook his head, said he would try; but it was useless. She said she 'couldn't do it,' and the agent frankly admitted that it was a failure.
