CANCELLING OF DEEDS AND WILLS. The word cancel comes from the Lat. cancelli (latticework), and a deed was formerly said to be cancelled when lines were drawn over it in the form of latticework. The word cancel is now used to signify any sort of obliteration.

The Court of Chancery in England gives relief against the effect of improper cancellation; on the other hand, it may order a deed which has been improperly obtained to be delivered up in order to be cancelled. The effect of the cancellation is to make the deed void. If a deed is given up to be cancelled, and the cancellation does not take place, it remains in force at law. But if an obligee deliver up an obligation to be cancelled, and the obligor do not afterwards cancel it, and the obligee happen to get it again into his hands, and sue the obligor on it, the latter cannot plead its voidance, for the deed still remains in force at lawalthough here, too,

What is really known as to the cure of C., may be stated in a few words. Modern pathological researches render it probable that a complete suspension of the progress of C. sometimes, though rarely, takes place; and individual tumours are found not unfrequently to undergo partial healing, or even to become entirely metamorphosed into inert cicatrices, while others, associated with them, continue to advance. The degree of rapidity of the advance of C. is also, as we have already stated, exceedingly variable. But these observations modify only to a very slight degree the general doctrine, that C. is a disease tending to a fatal issue, and hardly, if at all, under the control of remedies, as to its ultimate result.
