I. " Further Discussion of the Sun-spot Observations made at 

 South Kensington. A Report to the Solar Physics Com- 

 mittee." Communicated to the Royal Society- at the 

 request of the Committee. By J. NORMAN Lockyer, F.R.S. 

 Received June 27, 1889. 



I have previously reported the results of 700 observations of Sun- 

 spot spectra,* extending from November, 1879, to August, 1885. 

 The observations have been carried on continuously since the latter 

 date, but, in consequence of the small number of spots which have 

 been visible, the number of additional observations is only a little 

 over 150. Last year very few observations could be made. The 

 eighth hundred of observations dates from August, 1885, to August, 

 1887, and the first half of the ninth hundred from August, 1887, to 

 February, 1888. 



As on former occasions, I give Tables A, B, C, showing the numbers 

 of lines of iron, nickel, and titanium respectively which have been 

 recorded amongst the most widened. Table D shows the results in 

 the case of the lines which may at present be described as " unknown 

 lines."
