trade vs. profession

In ascertaining the amount which is so applicable, the plaintiffs contend that one of the learned professions may be taken as the standard, with as much propriety as the trade or art of a mechanic. The Court does not think so. The distinction between a profession and a trade is well understood; and they are seldom, if ever, confounded with each other in ordinary language. If the testatrix had contemplated what in the common intercourse of society is denominated a profession, she would scarcely have used a term which is generally received as denoting one of the mechanical arts.
