A Mark against Denmark.—At the beginning of last week it was midsummer weather, and not to have cast off winter clothing and donned light attire would have been deemed "Midsummer madness." But by Thursday "on a changé tout cela," except the clothes, and we were in midwinter! The Daily Telegraph's weather-clerk observed, that all "this resulted from a deep depression in Denmark." It certainly caused deep depression here; and there must be "something rotten in the State of Denmark" which ought to be looked to immediately. Ere these lines appear we hope—sincerely hope—that we shall have retraced our steps towards summer.
