General. 



In several Universities atmospheric electricity, terrestrial mag- 

 netism, geodesy, meteorology, and seismology, or some of these sub- 

 jects, are treated incidentally by professors of astronomy, physics, or 

 geology ; and it was intimated that additional provision could be made 

 for the study of such subjects if there were any demand for it. 



Electroanalysis. — Report of the Committee, consisting of Professor 

 F. S. Kipping {Chairman), Dr. F. M. Perkin {Secretary), Dr. G. T. 

 Beilby, Dr. T. M. Lowry, Professor W. J. Pope, and Dr. 

 H. J. S. Sand. 



The work on electroanalysis has been further elaborated during the 

 year by the publication of papers on the ' Electro-deposition of Metals, ' 

 by Dr. F. Mollwo Perkin and W. E. Hughes, 1 and by Dr. H. J. S. 

 Sand on ' Apparatus for the Rapid Electro-analyFical Separation of 

 Metals,' - and ' The Electro-determination of Lead as Peroxide.' 3 



Perkin and Hughes have devised and experimented with new 

 cathodes for the rapid deposition of metals. One simple, smooth 

 cathode is in the form of an elongated thimble, and with this, when 

 rapidly rotated, very smooth and even deposits can be obtained ; the total 

 active electrode surface is about 16'3 sq. cm. Extended work has shown, 

 however, that a platinum gauze cathode surrounding a spiral anode, 

 which is rapidly rotated, gives the most satisfactory results. For 

 separation of metals by means of graded potentials a funnel-shaped 

 vessel with a tap for running off the electrolyte is used. This vessel has 

 a side tube fused into it at about the centre to take the capillary of 

 the auxiliary electrode. This form of apparatus gave very good results, 

 and is very simple in working. 



The experiments referred to a year ago by Dr. Sand with an anode 

 made partly of glass and a cathode of metals, other than platinum, have 

 been completed by him, and will be published shortly. Satisfactory 

 results for copper were obtained with a cathode of silver, and for zinc 

 with a cathode of nickel. In the former case the electrolyte deposit may
