DR. C. CHREE: DISCUSSION OF KEW MAGNETIC DATA 
The eye can recognise in fig. 10 that the sunspot minimum vector is in advance of 
the sunspot maximum vector from 10 a.m. to 10 p.m., the angular difference being 
considerable in the early afternoon. The vector has, however, its maximum near 
I p.m. in both cases.

The year diagram from the eleven years does not show a close resemblance to the 
diagram of any individual month in fig. 8, a suggestive fact in connection with the 
significance of mean diurnal inequalities for the whole year. The equinoctial months 
are those whose diagrams show most resemblance to that for the whole year.
