Note 38 — HARVARD LAW REVIEW

In Morison v. Moat, 9 Hare, 241, 255 (1851), a suit for an injunction to restrain the use of a secret medical compound, Sir George James Turner, V. C., said: "That the court has exercised jurisdiction in cases of this nature does not, I think, admit of any question. Different grounds have indeed been assigned for the exercise of that jurisdiction. In some cases it has been referred to property, in others to contract, and in others, again, it has been treated as founded upon trust or confidence,—meaning, as I conceive, that the court fastens the obligation on the conscience of the party, and enforces it against him in the same manner as it enforces against a party to whom a benefit is given, the obligation of performing a promise on the faith of which the benefit has been conferred; but upon whatever grounds the jurisdiction is founded, the authorities leave no doubt as to the exercise of it."
