(381) Elton Copyh. 117.) The Duchy of Cornwall DESCENT, (distinction between "mediate" (q. v.) has a special mode of descent. See, also, and "immediate"). 6 Pet. (U. S.) 102, 119. a peculiar kind of descent mentioned by Coke, by which "the shield, armorie and armes" of a nobleman descend to such of his heirs as are able to bear them. Co. Litt. 27 a. 10. Trust and mortgage ustates. - An anomalous kind of descent takes place on the death of a mortgagee of land, or where a bare trustee dies intestate as to any corporeal or incorporeal hereditament of which he was seized in fee-simple. In the former case the legal personal representative of the mortgagee may, on payment of the mortgage debt, reconvey the land to the mortgagor, and, in the latter case, the hereditament vests like a chattel real in the legal personal representative of the deceased trustee. (Vendor and Purchaser Act, 1874, 24; Land Transfer Act, 1875, 248. See TRUSTEE. The latter provision does not apply to lands registered under the Land Transfer Act.) By the Conveyancing Act, 1881, ? 30, these provisions are repealed as to persons dying after the 31st December, 1881, and a different provision is made, (as to which, see TRUSTEE.) By section 4 of the same act, where a person dies after the 31st December, 1881, leaving an uncompleted contract for the sale of land enforceable against his heir or devisee, his personal representatives have power to convey the land so as to give effect to the contract. 216. (explained). 2 Pet. (U. S.) 58, 94. (in a statute). 18 Ohio. St. 311. (in copyhold custom). L. R. 4 Eq. DESCENT CAST is the same as what the older writers called a "descent which tolls entry." Where a person who had acquired land by disseisin, abatement or intrusion, died seised of the land, the descent of it to his heir took away or "tolled" the real owner's right of entry, so that he could only recover the land by an action. (Litt. § 385 et seq.; Co. Litt. 237 b.) The doctrine of descent cast was abolished by Stat, 3 and 4 Will. IV. c. 27. Shelf. R. P. Stat. 228. 2. The term seems to have originally meant "the happening of any descent," because the Conveylaw casts the land upon the heir. Litt. § 385; Watk. Desc. 33. 11. Descent per formam doni. -If an estate is limited to the heirs of the body of A., a deceased person who has left two sons, B. and C., B. takes by purchase as the first donee in tail, but nevertheless the estate devolves on his death as if he had taken it by descent from A., and, therefore, on B.'s death without issue the estate devolves on C. as the heir of the body of A. This is called a "descent per formam doni," ("according to the form of the gift,") although it is in strictness neither a descent nor a purchase. Fearne Rem. 81; Co. Litt. 26 b. See Wms. Real Prop. 58; Wms. Seis. 65. 12. Ex parte paterna, and materna. -Before the Inheritance Act there were several DESCENT THROUGH AND FROM, (construed). 2 Pet. (U. S.) 58, 90.
