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.]
