sin^2 alpha cos^2 phi + sin beta sin^8 phi -------------------------------------------- , tan^2 alpha cos^2 phi + tan^2 beta sin^2 phi then cos^2 beta tan phi = cos^2 alpha tan^2 lambda, unless alpha = beta ± n pi. I am bound to state that I could not answer any one of these interrogations myself, and that my readers must therefore allow for the bias of envy in the expression of my belief that to have been able to answer the sort of questions which the First of May once used to propose to English children,--whether they knew a cowslip from an oxslip, and a blackthorn from a white,--would have been incomparably more to the purpose, both of getting their living, and liking it. NOTES AND CORRESPONDENCE. The following expression of the wounded feelings of the 'Daily News' is perhaps worth preserving:-- "Mr. Ruskin's 'Fors Clavigera' has already become so notorious as a curious magazine of the blunders of a man of genius who has travelled out of his province, that it is perhaps hardly worth while to notice any fresh blunder. No one who writes on financial subjects need be at all surprised that Mr. Ruskin funnily misinterprets what he has said, and we have ourselves just been the victim of a misinterpretation of the sort. Mr. Ruskin quotes a single sentence from an article which appeared in our impression of the 3rd of March, and places on it the interpretation that 'whenever you have reason to think that anybody has charged you threepence for a twopenny article, remember that, according to the "Daily News," the real capital of the community is increased.' We need hardly tell our readers that we wrote no nonsense of that kind. Our object was to show that the most important effect of the high price of coal was to alter the distribution of the proceeds of production in the community, and not to diminish the amount of it; that it was quite possible for real production, which is always the most important matter in a question of material wealth, to increase, even with coal at a high price; and that there was such an increase at the time we were writing, although coal was dear. These are certainly very different propositions from the curious deduction which Mr. Ruskin makes from a single short sentence in a long article, the purport of which was clear enough. There is certainly no cause for astonishment at the blunders which Mr. Ruskin makes in political economy and finance, if his method is to rush at conclusions without patiently studying the drift of what he reads. Oddly enough, it may be added, there is one way in which dear coal may increase the capital of a country like England, though Mr. Ruskin seems to think the thing impossible. We are exporters of coal, and of course the higher the price the more the foreigner has to pay for it. So far, therefore, the increased price is advantageous, although on balance, every one knows, it is better to have cheap coal than dear."
