Reply to GA's letter on Charles Babbage's calculating machine.
Gives GA some accounting of standard weights in Britain, and feels that it would be worth acquiring Robinson estate weight [see GA's 1842-9-22].
A letter of introduction, asking GA to show the observatory to a Mr. Knipping from Hanover, a relative of JH's aunt Caroline.
Arranging a visit for GA to Collingwood.
Final arrangements for GA's visit to JH [see GA's 1842-3-15].
As many Russian observatories are now involved in magnetic observations, JH thinks the British observations should continue [see GA's 1842-1-22].
