112 PROCEEDINGS OF SECTION A. 



In the second marked position of the coil one scale division 

 corresponds to '001 amperes. 



The scale was so curved as to give readings directly of the 

 tangent of the angle of deflexion and a table of small corrections 

 depending on the finite size of the winding of the coil was 

 provided. Special features were the damping by clove oil, and the 

 tine adjustment of the controlling magnet. 



[The apparatus referred to in these papers was exhibited and 

 remarks were made by the President, Professor Bragg, Mr. 

 Sutherland, and Mr. McFarlane. 



After a vote of thanks to the authors of the papers, the 

 President, Mr. Ellery, recommended that some steps should be 

 taken with respect to the Meteorological work discussed on the 

 previous day. He proposed that a Committee should be appointed 

 " for the purjDose of reporting on the present state of Meteoro- 

 logical Science, and on the best method of arranging some scheme 

 for concerted action." After some dicussion it was agreed that 

 the appointment of such a Committee should be recommended to 

 the Association, and that the details should be arranged by Mr. 

 Ellery. 



On the motion of Professor Bragg a vote of thanks was 

 tendered to the President of the Section, and the meeting was 

 adjourned till 1889.]
