If, when applying a will, it is found that there is an imperfect description, or that no person or property exactly answers the description, mistakes and omissions must be corrected, if the error appears from the context of the will or from extrinsic evidence; but evidence of the declarations of the testator as to his intention cannot be received. R.L. 1910, Sec. 8404. R.L.1910, § 8404.
