Abstract
I SEE that Prof. Hill regards the barometric evidence as favourable to the hypothesis that the sun is most powerful when there are fewest spots on his surface. Perhaps I may therefore be allowed to state the reasons which have induced me to entertain a contrary opinion, which are, I imagine, the same as have also occurred to others. I quite agree with Prof. Hill that the true relation between the variations of sun-spot area and barometric pressure will ultimately be discovered by means of the admirable weather-maps of the United States. Nevertheless, we must wait until these have been produced in sufficient number before we attempt to generalise.
