magnetic perturbations, by Selim Lemstrom. 

 ' On the construction of magnets of constant 

 intensity under changes of temperature,' 

 by J. E. Ashworth. ' Antrag auf Massnah- 

 men zur systematischen Erforschung der 

 Secularvariationen der erdmagnetischen 

 Elemente,' von Dr. Ad. Schmidt in Gotha. 

 ' On magnetic observatories at Funafuti,' 

 by Captain Crealj. ' Some remarks on the 

 construction of magnetic observatories,' by 

 Dr. Snellen. 



In joint discussion with Section A there 

 was read a report of the committee on com- 

 paring and reducing magnetic observations, 

 and in joint discussion with Sections A and 

 G on the magnetic and electrolytic actions 

 of electrical railways. Communications on 

 this subject were made by C. A. Schott, 

 Professor A. W. Rilcker, Drs. von Eschen- 

 hagen and von Bezold, W. H. Preece, Sig- 

 ner Palazzo and Professor Fleming. 



The results of the deliberations of the 

 Conference were embodied in the report to 

 be made to the International Meteorological 

 Conference at its next meeting, and publica- 

 tion may be looked for by that organization 

 and in part in the Proceedings of the Bristol 

 Meeting. It is conceded by those who took 

 an active part in the deliberations that 

 this, the first international magnetic con- 

 ference, has been most satisfactory in its 

 results, and it is hoped that its fruits will 

 show that the labor spent at Bristol was 

 well directed. 



Too much praise cannot be bestowed 

 upon the effective manner in which the 

 sessions of the Conference were pi-esided 

 over, which in no small degree contributed 

 to the success of the meeting, nor will the 

 members ever forget the cordiality of recep- 

 tion and generous hospitality extended to 

 them by their President, the British Asso- 

 ciation and the Chamber of Commerce of 

 the city of Bristol.
