Calls attention to vol. 3 of Toronto observations, where Edward Sabine, [T. R.] Robinson, and HL expressed their views on continuing magnetic observations. Emphasizes importance of discovering physical and mathematical laws that govern magnetic phenomena. Sufficient data already exist for this. Recommends continuing hourly observations for five more years at seven foreign observatories (listed). [JH note: Routing slip to B.A.A.S. committee, instructing each member to read and forward HL's recommendations.]

R.S.L. committee for considering continuance of magnetic observations has recommended that hourly observations be carried out at Falkland Islands, Newfoundland, and Vancouver Island. Alternate stations are Ceylon and Bermuda. Will not print all observations. Hopes colonial governments will participate. JH and William Whewell will be at [B.A.A.S. meeting in] Leeds.

R.S.L. committee recommends continuing three magnetic observatories at Falkland Islands, Newfoundland, and Vancouver Island.

Forwarded JH's letter of 8 Aug. 1858 to members of magnetic committee, who will respond before B.A.A.S. meeting in Leeds next month. Asks that both committees meet jointly on first day. Edward Sabine is willing to superintend new series of observations proposed by JH.
