The general newspaper office, often has handy men in connection therewith who will on the shortest notice write "a highly interesting article" on subjects they know nothing whatever about. A good encyclopaedia and shrewdness to keep from error, is the talent required. But sometimes these sharp fellows get caught, and once in a while they try their hand with professedly scientific magazines. Prof. Gray recently showed up one of these "fancy sketches" in the American Naturalist, and here is a choice bit of the same sort, as translated by the Scientific American from La Nature. "While the orchidaceae indigenous in the temperate zones are generally annual or biennial herbs of from six inches to eighteen inches in height, the tropical zones possess a great many which are perennial." There are a great many funny things in this article, but the "generally annual" orchids of the temperate zone is enough for our pages.
