A reference to practical considerations will be found to run all through the subject. Take another instance. The plaintiff declared on a mutual agreement between himself and the defendant that he would sell, and the defendant would buy, certain Donskoy wool, to be shipped by the plaintiff at Odessa, and delivered in England. Among the stipulations of the contract was one, that the names of the vessels should be declared as soon as the wools were shipped. The defence was, that the wool was bought, with the knowledge of both parties, for the purpose of reselling it in the course of the defendant's business; that it was an article of fluctuating value, and not salable until the names of the vessels in which it was shipped should have been declared according to the contract, but that the plaintiff did not declare the names of the vessels as agreed. The decision of the court was given by one of the greatest technical lawyers that ever lived, Baron Parke; yet he did not dream of giving any technical or merely logical reason for the decision, but, after stating in the above words the facts which were deemed material to the question [339] whether declaring the names of the vessels was a condition to the duty to accept, stated the ground of decision thus: "Looking at the nature of the contract, and the great importance of it to the object with which the contract was entered into with the knowledge of both parties, we think it was a condition precedent." /1/ [340] LECTURE X. -- SUCCESSIONS AFTER DEATH. In the Lecture on Possession, I tried to show that the notion of possessing a right as such was intrinsically absurd. All rights are consequences attached to filling some situation of fact. A right which may be acquired by possession differs from others simply in being attached to a situation of such a nature that it may be filled successively by different persons, or by any one without regard to the lawfulness of his doing so, as is the case where the situation consists in having a tangible object within one's power.
