Before he sends the 'Instructions' to the press would like to know if there is any objection to the use that he has made of JH's Admiralty Manual.

Henry Lawson has nominated EL for the R.S.L. and would be grateful if JH would add his name to the certificate. Has just received an 11' refracting telescope from Lawson.

Has had several gifts of books for the Midland Observatory.

Believes that Edward Sabine has brought J. H. Lefroy's paper on the Aurora Borealis to JH's notice. Now presents another report on this subject, with comments.

Has made a globe of J. H. Mädler's lunar observations. Would JH accept one as a gift; if so, how can he send it?

Has received the papers JH sent and values them highly. Can JH advise him on making regular observations of sun spots. Explains his apparatus.

JH's obliging note concerning corrections to the maps in JM's Handbook for France has been sent to him at Knock.
