Explains efforts at using a makeshift apparatus for 'fixing the spectrum.' Discusses current confusion and ultimate hope surrounding JF's meteorological recommendations. In a postscript, notes observations of meteors in Persei.
JH has given away his sweeping telescope to [Johann] Hausmann and the 5-ft. Newtonian reflector to the R.A.S. to be preserved 'long after I and all the little ones are dead and gone.' The skies have been excellent for JH to observe variable stars and to connect the northern with the southern magnitudes. Proved that Alpha Orionis is both a variable star and a periodical star.
