MAGNETIC AL OBSERVATIONS* 



Resolved, — 1. That the British Association views with high interest 

 the system of Simultaneous Magnetic Observations which have been for 

 some time carrying on in Germany and in various parts of Europe, and 

 the important results towards which they have already led; and that they 

 consider it highly desirable that similar series of observations, to be re- 

 gularly continued in correspondence with and in extension of these, 

 should be instituted in various parts of the British dominions. 



2. That this Association considers the following localities as particu- 

 larly important : 



Canada, Van Diemen's Land, 



Ceylon, Mauritius, or the 



St. Helena, Cape of Good Hope ; 



and that they are willing to supply Instruments for the purpose of obser- 

 vation. 



3. That in these series of observations, the three elements of horizon- 

 tal direction, dip, and intensity, or their theoretical equivalents, be in- 

 sisted on, as also their hourly changes, and on appointed days their 

 momentary fluctuations. 



4. That this Association views it as highly important that the defici- 

 ency yet existing in our knowledge of Terrestrial Magnetism in the 

 Southern Hemisphere should be supplied by observations of the magne- 

 tic direction and intensity, especially in the higher latitudes, between 

 the meridians of New Holland and Cape Horn; and they desire strongly 

 to recommend to Her Majesty's Government the appointment of a naval 

 expedition directed expressly to that object. 



5. That in the event of such expedition being undertaken, it would be 

 desirable that the officer charged with its conduct should prosecute 

 both branches of observations alluded to in Resolution 3, so far as cir- 

 cumstances will permit. 



6. That it would be most desirable that the observations so perform- 

 ed, both in the fixed stations and in the course of the expedition, should 

 be communicated to Prof. Lloyd. 



7. That Sir John Herschel, Mr. Whewell, Mr. Peacock, and Prof. 

 Lloyd be appointed a Committee to represent to Government these re_ 

 commendations. 



8. That the same gentlemen be empowered to act as a Committee,,
