Where the subject-matter of the gifts is not so defined in the will as to be ascertained with reasonable certainty; 25 Pa. 460 ; 12 Gratt. 196; 1 Jarm. Will 317; 1Swanst. 201; the person intended to be benefited may not be so described or named that be can be identified. But, in general, by re- jecting obvious mistakes, this kind of un- certainty is overcome; 1 Jarm. Wills 330- 348, and notes. Determinate meanings have now been assigned to numerous doubt- ful words and phrases, and rules of con- struction adopted by the courts, which render devises void for uncertainty less frequent than formerly; 1 Jarm. Wills 356-383. A will otherwise effective, should not be refused probate because certain be- quests contained therein are void for un- certainty; 74 Cal. 144; 27 Abb. N. C. 499; 4 Misc. Rep. 233; 76 Hun 469; 89 Tenn. 219. By statute in California when the validity of a gift, devise, or trust under a will is involved in an action, the will is admissible as evidence, and the validity of the gift, devise, or trust shall be deter- mined; Laws, 1895, p. 77. The testator's body cannot be disposed of by his will, because the law recognizes no property in a dead body, and it is the duty of the executor to bury it; 21 Am. L. Reg. N. 8. 508. PAROL EVIDENCE, HOW FAR ADMISSIBLE. The rule in regard to the admissibility of parol evidence to vary, control, or to ren- der intelligible the words of a will, is not essentially different from that which ob- tains in regard to contracts. It may be received to show the state of the testator, the nature and condition of his property, his relation to the contestants, and all the sur- rounding circumstances. But this is done to place the court in the condition of the tes- tator, in order as far as practicable to enable them the more fully to understand the sense in which he probably used the lan- guage found in his will; 1 Nev. & M. 524; 15 Pick. 400; 1 Phill. Εν. 532-547; 1 Greenl. Ev. §§ 287-289; 1 Jarm. Wills 349, and notes; 2 Ired. 192. To ascertain the intention of testator, circumstances exist- ing at the date of the execution of a will, but not those subsequent thereto, are ad- missible in evidence; 133 N. Y. 456; 154 Pa. 523; 92 Ga. 216. Letters and oral dec- larations of the testator are not admis- sible to show the intention of the testator; 2 Vern. 625; 14 Johns. 1; 2 W. & S. 455. But see 22 Wend. 148. Parol evidence is not admissible to supply any word or de- fect in the will; 7 Gill & J. 127; 8 Conn. 254; 23 Barb. 285; 27 Ala. N. S. 489. Parol declarations of the testator about the time of making the will are often admitted to show the state of mind, capacity, and un- derstanding of the testator; but they are not to be used to show his intention; that must be learned from the language used; 8 Conn. 254; 156 Mass. 379; id. 265. Parol evidence is inadmissible to prove that a gift to a nephew was really intended for the wife's nephew of the same name; 187 Pa. 118; but see 12 Harv. L. Rev. 210. See, generally, Tud. Lead. Cas. R. P. 918; Wigram, Wills. As to construction of wills see DEVISE ;
