  <dc:title>Letter, from Alexander R. Clarke to Sir John Herschel, dated at Southampton</dc:title>
  <dc:description>Autograph letter signed by sender. Thanks for sending him his essay on the yard, pendulum and metre. Hopes it will engage the attention of the public. A measure of 50 would be very convenient.</dc:description>
