  <dc:title>Letter, from Sir John Herschel to William Radcliffe Birt, dated at Collingwood</dc:title>
  <dc:description>Autograph letter signed by sender. Fully examined William Radcliffe Birt's report [on barometer observations]. Agrees to combine British and Continental observations. Curves clearly show atmospheric processes. Likes William Radcliffe Birt's suggestion of tracing atmospheric wave beyond 24 hours; will propose this to B.A.A.S. Irregularity of Asiatic and South African data.</dc:description>
