Would like to ask a few more questions regarding JH's method outlined in his last letter. Can UL submit it to the Institute?
Has just received JH's letter giving details of an interesting auroral phenomenon. Has been experimenting with wire insulates. Henry Lawson has observed streams of red light resembling aurora.
Asks JH's opinion about GA's plan not to print a separate volume of magnetic and meteorological observations for 1848.
Will reconsider the proposal about printing observations [see JH's 1849-3-29], and get back to JH.
Sends sample of photographic lenses ground by JJ. Asks JH for formula of curvature to admit more light.
Shall send a catalogue of double stars observed by [W. S.] Jacob. Gives some information about several measurements to establish standards.
Has little advice to offer JH about time calculation [see JH's 1849-3-29], except for fairly standard reminders.
Regarding the 'chilled' casting of a telescope.
It is now time that they speak to John Russell (1st Earl Russell) concerning [Francis?] Ronald[s]. Would next Friday suit him?
Finds that some of the pages from the paper JH recently sent him are missing. Please send if he still has them. H. P. Brougham (Baron Brougham and Vaux) does not mean to attack the undulating theory. Regarding solar spots and the surface of the moon.
Regarding the early history of the calendar. Comments on the various versions.
Has received three packets, dated and initialed. Further comments regarding Julius Caesar and the calendar.
Thanks JH for Cape Results sent through [F. G. W.] Struve. Further grateful for the N. L. Lacaille and Jérôme Lalande works sent to the observatory. Appreciates reduction of the moon results as well as the magnetic observation of 1845. Reveals new development in double star zones[?]. Comments on making magnetic observations.
Delay in printing WK's meteorology paper.
Expresses appreciation for being elected an associate of the R.A.S.
