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.
Sends W. K. Clifford subscription.
Has been unwell and hardly able to do anything. Has seen Andrew Clark.
