I. MAGNETIC OBSERVATIONS. 



The Magnetographs have worked uninterruptedly throughout the 

 year. 



The curves have been quite free from any large fluctuations, and 

 indeed no unusual disturbance has been registered for a long time 

 past. The most notable perturbations recorded took place on July 3, 

 September 18, and October 2, but the extreme oscillation of the Decli- 

 nation Magnet on any of these days did not exceed 30', while the 

 change of Horizontal Force was less than O02 Gaussian unit.
