ESTIMATION OF VALUES. As the value of most things is variable, according to circumstances, the law in many cases determines the time at which the value of a thing should be taken; thus, the value of an advancement, is to be taken at the time of the gift. 1 Serg. & R. 425. Of a gift in frank-marriage, at the time of partition between the parceners, and the bringing of the gift in frank-marriage into hotchpot. But this is a case sui generis. Co. Lit. §273; 1 Serg. & R. 426. Of the yearly value of properties; at the time of partition. Tho. Co. Lit. 820. Of a bequest of so pieces of coin; at the time of the will made. Godolph, 0. L. 273, part 3, chap. 1. §3. Of assets to make lineal warranty a bar; at the time of the descent. Co. Lit. 374, b. Of lands warranted; at the time of the warranty. Beames' Glanv. 75 n.; 2 Serg. & Rawle, 444, see Eviction 2. Of a ship lost at sea; her value is to be taken at the port from which she sailed, deducting one-fifth; 2 Serg. & Rawle, 258; 1 Caines, 572; 2 Condy. Marshall, 545; but different rules prevail on this subject in different nations. 2 Serg. & R. 259. Of goods lost at sea; their value is to be taken at the port of delivery. 2 Serg. & R. 257. The comparative value of a life estate, and the remainder in fee, is one-third for the life and two-thirds for the remainder in fee; and moneys due upon a mortgage of lands devised to one for life, and the remainder in fee to another, are to be apportioned by the same rule. 1 Vern. 70; 1 Chit.
