DERIVATIVE. Coming from another; taken from something preceding, secondary; as derivative title, which is that acquired from another person. There is considerable difference between an original and a derivative title. When the acquisition is original, the right thus acquired to the thing becomes property, which must be unqualified and unlimited, and since no one but the occupant has any right to the thing, he must have the whole right of disposing of it. But with regard to derivative acquisition, it may be otherwise, for the person from whom the thing is acquired may not have an unlimited right to it, or he may convey or transfer it with certain reservations of right. Derivative title must always be by contract.
     2. Derivative conveyances are, those which presuppose some other precedent conveyance, and serve only to enlarge, confirm, alter, restrain, restore, or transfer the interest granted by such original conveyance, 3 Bl. Com. 321.

In the case of S-cal however the mean lead levels of retired workers were significantly lower (p less than 0.05) than those who were on job It is known that supra gingival calculus is largely composed of mixed phases of apatite and ss-tri calcium compounds formed from the deposition of calcium and phosphate in saliva [10] In view of the presence of metallic taste due to lead in saliva of lead workers [16] it is reasonable to expect that composition of S-cal is likely to be influenced by oral environment.
