Will provide the siren.
Has observed, perhaps erroneously, that certain plants were excited to movement by a prolonged high note on the bassoon. Would now like to try a siren and asks JT to bring one from the Royal Institution.
Returns the siren; the plants "ill luck to them, are not sensitive to aerial vibrations". Is ashamed of his blunder.
